Dieses mal jedoch nicht über einen Monat gezogen sondern in einer Woche werden 5 Städte besucht und mein Kollege &lt;a href="http://blogs.msdn.com/cbinder"&gt;Christian Binder&lt;/a&gt; wird auch mit von der Partie sein.&lt;/p&gt;  &lt;p&gt;In Visual Studio 2010 kommen so viele neue Elemente dazu das wir einfach in &lt;a href="http://www.microsoft.com/germany/msdn/techtalk/aktuell/default.mspx"&gt;diesem TechTalk&lt;/a&gt; verschiedene Aspekte live im Coding demonstrieren wollen und auf hoffentlich viele Fragen eingehen dürfen. Ganz nach dem Motto: “Keine Slides! Nur Code!”&lt;/p&gt;  &lt;p&gt;Hier der Auszug von der MSDN TechTalk Anmeldeseite:&lt;/p&gt;  &lt;blockquote&gt;   &lt;p&gt;&lt;em&gt;Der letzte MSDN TechTalk in diesem Jahr nimmt Sie mit auf eine Reise zur nächsten Version von Visual Studio: Visual Studio 2010. Dabei werden Christian Binder und Dariusz Parys die interessantesten Aspekte der neuen Entwicklungsumgebung vorstellen: von Verbesserungen in den einzelnen Frameworks bis hin zu neuen Möglichkeiten in den Application Lifecycle Management Tools, die das Testen und die Entwicklung im Team einfacher machen, wird dieser TechTalk die verschiedenen Aspekte mit Hilfe von Live Codings demonstrieren. Das heißt ganz klar: Keine Slides! Nur Code!&lt;/em&gt;&lt;/p&gt; &lt;/blockquote&gt;  &lt;blockquote&gt;   &lt;h4&gt;Die Termine:&lt;/h4&gt; &lt;/blockquote&gt;  &lt;ul&gt;   &lt;ul&gt;     &lt;li&gt;&lt;a href="http://msevents.microsoft.com/CUI/EventDetail.aspx?EventID=1032422667&amp;amp;Culture=de-DE"&gt;30.11.

München&lt;/a&gt;&lt;/li&gt;   &lt;/ul&gt; &lt;/ul&gt;  &lt;p&gt;An manchen Terminen werden wir vermutlich deutlich überziehen, das dürfte Karlsruhe, Berlin und München sein. In Köln und Hamburg sind wir leider an die Öffnungszeiten des Microsoft Office gebunden.&lt;/p&gt;  &lt;p&gt;Ich freue mich schon auf viele Teilnehmer und Fragen, bis dann!&lt;/p&gt;  &lt;p&gt;Link: &lt;a href="http://www.microsoft.com/germany/msdn/techtalk/aktuell/default.mspx"&gt;Offizielle TechTalk Anmeldeseite&lt;/a&gt;&lt;/p&gt;&lt;img src="http://blogs.msdn.com/aggbug.aspx?PostID=9854259" width="1" height="1"&gt;</description><category domain="http://blogs.msdn.com/dparys/archive/tags/Connected+Systems/default.aspx">Connected Systems</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Visual+Studio/default.aspx">Visual Studio</category><category domain="http://blogs.msdn.com/dparys/archive/tags/C_2B002B002F00_CLI/default.aspx">C++/CLI</category><category domain="http://blogs.msdn.com/dparys/archive/tags/WCF/default.aspx">WCF</category><category domain="http://blogs.msdn.com/dparys/archive/tags/WF/default.aspx">WF</category><category domain="http://blogs.msdn.com/dparys/archive/tags/VSTS_2F00_TFS/default.aspx">VSTS/TFS</category><category domain="http://blogs.msdn.com/dparys/archive/tags/C_2300_/default.aspx">C#</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Coding4Fun/default.aspx">Coding4Fun</category><category domain="http://blogs.msdn.com/dparys/archive/tags/ASP.NET/default.aspx">ASP.NET</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Silverlight/default.aspx">Silverlight</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Security/default.aspx">Security</category><category domain="http://blogs.msdn.com/dparys/archive/tags/MSDN/default.aspx">MSDN</category><category domain="http://blogs.msdn.com/dparys/archive/tags/VSTS/default.aspx">VSTS</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Events/default.aspx">Events</category><category domain="http://blogs.msdn.com/dparys/archive/tags/TechTalk/default.aspx">TechTalk</category><category domain="http://blogs.msdn.com/dparys/archive/tags/.NET+Framework/default.aspx">.NET Framework</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Testing/default.aspx">Testing</category><category domain="http://blogs.msdn.com/dparys/archive/tags/PLINQ/default.aspx">PLINQ</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Tools/default.aspx">Tools</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Data+Access/default.aspx">Data Access</category><category domain="http://blogs.msdn.com/dparys/archive/tags/C_2B002B00_/default.aspx">C++</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Services/default.aspx">Services</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Dynamic+Languages/default.aspx">Dynamic Languages</category><category domain="http://blogs.msdn.com/dparys/archive/tags/LINQ/default.aspx">LINQ</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Parallel+Computing/default.aspx">Parallel Computing</category><category domain="http://blogs.msdn.com/dparys/archive/tags/WPF/default.aspx">WPF</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Entity+Framework/default.aspx">Entity Framework</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Community/default.aspx">Community</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Coding/default.aspx">Coding</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Visual+Studio+2010/default.aspx">Visual Studio 2010</category></item><item><title>Wie baue ich einen eigenen LINQ Provider</title><link>http://blogs.msdn.com/dparys/archive/2008/12/10/wie-baue-ich-einen-eigenen-linq-provider.aspx</link><pubDate>Wed, 10 Dec 2008 13:45:36 GMT</pubDate><guid isPermaLink="false">91d46819-8472-40ad-a661-2c78acb4018c:9190470</guid><dc:creator>dparys</dc:creator><slash:comments>0</slash:comments><comments>http://blogs.msdn.com/dparys/comments/9190470.aspx</comments><wfw:commentRss>http://blogs.msdn.com/dparys/commentrss.aspx?PostID=9190470</wfw:commentRss><wfw:comment>http://blogs.msdn.com/dparys/rsscomments.aspx?PostID=9190470</wfw:comment><description>&lt;p&gt;Eigentlich nur eine kurze Notiz für mich, aber auch brauchbar für alle die einen eigenen LINQ Provider schreiben möchten.&lt;/p&gt;

Den Mehraufwand hat man gerne selbst getragen (oder tragen lassen, Entschuldigung schon mal an dieser Stelle, Ihr wisst wer gemeint ist) um das Projekt / Produkt auf eine neue technische Ebene zu heben. Meist hat sich der Aufwand auch gelohnt.&lt;/P&gt;
&lt;P&gt;Seit ich bei Microsoft bin, liegt hier mein Fokus natürlich verstärkt auf die Microsoft Technologie. Ich möchte mal sagen das ich nicht diesen &lt;A href="http://ralfw.blogspot.com/2008/05/microsoftdmmerung.html" mce_href="http://ralfw.blogspot.com/2008/05/microsoftdmmerung.html"&gt;Bias&lt;/A&gt; habe über den Ralf Westphal geschrieben hat, aber mein "Abdriften" in andere Technologie Welten ist definitiv geringer geworden. &lt;/P&gt;
&lt;P&gt;Warum schreibe ich das eigentlich? Ganz einfach, nach dem Auswerten der Technical Summit Feedbacks ist mir aufgefallen das die Themen kaum Relevanz für die Teilnehmer hatten und ich nicht von mir ausgehen möchte was relevant ist. Was ich wirklich Cool finden würde, wären Kommentare was für &lt;STRONG&gt;&lt;EM&gt;Sie relevante Softwareentwicklungsthemen &lt;/EM&gt;&lt;/STRONG&gt;sind.&lt;/P&gt;&lt;img

den letzten Tagen habe ich öfters über das Thema ADO.NET Entity Framework gesprochen. Eine der häufigsten Fragen war: “Wie kann ich Daten dynamisch abfragen?”. Es gibt verschiedene Möglichkeiten das zu Bewerkstelligen, heute möchte ich eine generische Aufzeigen: Composable Queries.&lt;/p&gt;  &lt;p&gt;LINQ Abfragen gegen Datenbanken liefern in der Regel ein spezialisiertes Query Object zurück, bei LINQ to Entities (ADO.NET Entity Framework) wäre das die Klasse &lt;em&gt;ObjectQuery&amp;lt;T&amp;gt;. &lt;/em&gt;&lt;/p&gt;  &lt;p&gt;Die Abfrage&lt;/p&gt;  &lt;div&gt;   &lt;div style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;     &lt;pre style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; margin: 0em; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;&lt;span style="color: #606060"&gt;   1:&lt;/span&gt; var query = from c &lt;span style="color: #0000ff"&gt;in&lt;/span&gt; context.Customers&lt;/pre&gt;

    &lt;pre style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; margin: 0em; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;&lt;span style="color: #606060"&gt;   2:&lt;/span&gt;             select c;&lt;/pre&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;liefert somit als Resultat das Objekt &lt;em&gt;ObjectQuery&amp;lt;Customers&amp;gt;&lt;/em&gt; zurück (&lt;em&gt;Anm.: Wenn es sich um ein Default Mapping der Northwind Datenbank handelt&lt;/em&gt;). Schaut man sich die Schnittstellen an, die &lt;em&gt;ObjectQuery&amp;lt;T&amp;gt;&lt;/em&gt; implementiert, entdeckt man die Schnittstellen &lt;em&gt;IQueryable&lt;/em&gt; und &lt;em&gt;IQueryable&amp;lt;T&amp;gt;&lt;/em&gt;. Die Grundlage um Abfragen miteinander flexibel zu kombinieren.&lt;/p&gt;

&lt;p&gt;&lt;a href="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot1_4.png"&gt;&lt;img style="border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px" title="shot1" border="0" alt="shot1" src="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot1_thumb_1.png" width="348" height="278" /&gt;&lt;/a&gt; &lt;/p&gt;

&lt;p&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;

&lt;p&gt;Die obige Abfage ist definiert aber nicht ausgeführt. Der entsprechend visualisierte T-SQL Code des Providers sieht bisher wie folgt aus:&lt;/p&gt;

&lt;div&gt;
  &lt;div style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;
    &lt;pre style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; margin: 0em; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;&lt;span style="color: #606060"&gt;   1:&lt;/span&gt; &lt;span style="color: #0000ff"&gt;SELECT&lt;/span&gt;&lt;/pre&gt;

  &lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;&lt;em&gt;Anm.: Den T-SQL Code kann man sich über eine ToTraceString() Methode von ObjectQuery anzeigen lassen.&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;Die Abfrage lässt sich noch erweitern, zum Beispiel möchte ich nur alle Kunden aus Deutschland angezeigt bekommen.&lt;/p&gt;

&lt;div&gt;
  &lt;div style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;
    &lt;pre style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; margin: 0em; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;&lt;span style="color: #606060"&gt;   1:&lt;/span&gt; var query2 = query.Where( customer =&amp;gt; customer.Country == &lt;span style="color: #006080"&gt;&amp;quot;Germany&amp;quot;&lt;/span&gt; );&lt;/pre&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;Damit wird die bestehende Abfrage um die Where Bedingung ergänzt und der T-SQL Code enthält die entsprechende Bedingung:&lt;/p&gt;

&lt;div&gt;
  &lt;div style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;

    &lt;pre style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; margin: 0em; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;&lt;span style="color: #606060"&gt;  14:&lt;/span&gt; &lt;span style="color: #0000ff"&gt;FROM&lt;/span&gt; [dbo].[Customers] &lt;span style="color: #0000ff"&gt;AS&lt;/span&gt; [Extent1]&lt;/pre&gt;

    &lt;pre style="border-bottom-style: none; padding-bottom: 0px; line-height: 12pt; border-right-style: none; background-color: #f4f4f4; margin: 0em; padding-left: 0px; width: 100%; padding-right: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-top-style: none; color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px"&gt;&lt;span style="color: #606060"&gt;  15:&lt;/span&gt; &lt;span style="color: #0000ff"&gt;WHERE&lt;/span&gt; N&lt;span style="color: #006080"&gt;'Germany'&lt;/span&gt; = [Extent1].[Country]&lt;/pre&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;Und so lässt sich das ganze fortsetzen. &lt;/p&gt;

&lt;p&gt;Damit lassen sich dynamische Abfragefilter in einer Anwendung erstellen, die dem Benutzer die Möglichkeit geben, Spalten auszuwählen, Bedingungen anzugeben und Sortierungskriterien zu bestimmen. In einer kleinen Beispielanwendung hat der Benutzer die Möglichkeit die Kunden Tabelle der Northwind Datenbank entsprechend einzuschränken. &lt;/p&gt;

&lt;p&gt;&lt;a href="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot2_2.png"&gt;&lt;img style="border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px" title="shot2" border="0" alt="shot2" src="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot2_thumb.png" width="358" height="203" /&gt;&lt;/a&gt; &lt;/p&gt;

&lt;p&gt;Der Benutzer kann die Anzahl der Spalten minimieren, einen Filter auf das anzuzeigende Land zu setzen und auch eine Sortierung wählen. &lt;/p&gt;

&lt;p&gt;Selektiert man keinen Filter wird die Abfrage entsprechend 1:1 im GridView angezeigt.&lt;/p&gt;

&lt;p&gt;&lt;a href="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot3_2.png"&gt;&lt;img style="border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px" title="shot3" border="0" alt="shot3" src="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot3_thumb.png" width="538" height="148" /&gt;&lt;/a&gt; &lt;/p&gt;

&lt;p&gt;Eine Auswahl einiger Filterkriterien erzeugt ein anderes Ergebnis:&lt;/p&gt;

&lt;p&gt;&lt;a href="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot4_2.png"&gt;&lt;img style="border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px" title="shot4" border="0" alt="shot4" src="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/DynamischeAbfragenmitLINQ_71FB/shot4_thumb.png" width="348" height="413" /&gt;&lt;/a&gt; &lt;/p&gt;

&lt;p&gt;Im Anwendungscode wird die gleiche Query als Grundlage genommen. Diese wird in der Methode &lt;em&gt;ConstructBaseQuery&lt;/em&gt; erzeugt. Annhand der Selektion der Kriterien wird diese Abfrage im Code modifiziert. Hier der entsprechende Sourcecode:&lt;/p&gt;

&lt;p&gt;Für die Projektion des Anonymen Typen (Zeile 52-57) musste ich allerdings ein einfaches &lt;em&gt;IQueryable&lt;/em&gt; zurückliefern, deshalb die Variable &lt;em&gt;q2 &lt;/em&gt;(Zeile 20).&lt;/p&gt;

&lt;p&gt;Dies ist eine Möglichkeit dynamische Abfragen mit LINQ zu erstellen und hat den Charme das dies mit jedem &lt;em&gt;IQueryable&lt;/em&gt; / &lt;em&gt;IQueryable&amp;lt;T&amp;gt;&lt;/em&gt; funktioniert und somit bei LINQ to SQL wie auch bei LINQ to Entities und LINQ to “was weiß ich was für ein Provider eingesetzt wird” funktioniert.&lt;/p&gt;&lt;img src="http://blogs.msdn.com/aggbug.aspx?PostID=8999091" width="1" height="1"&gt;</description><category domain="http://blogs.msdn.com/dparys/archive/tags/C_2300_/default.aspx">C#</category><category domain="http://blogs.msdn.com/dparys/archive/tags/.NET+Framework/default.aspx">.NET Framework</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Data+Access/default.aspx">Data Access</category><category domain="http://blogs.msdn.com/dparys/archive/tags/LINQ/default.aspx">LINQ</category></item><item><title>Silverlight 2 Beta 2 und ADO.NET Data Services</title><link>http://blogs.msdn.com/dparys/archive/2008/06/13/silverlight-2-beta-2-und-ado-net-data-services.aspx</link><pubDate>Fri, 13 Jun 2008 10:23:47 GMT</pubDate><guid isPermaLink="false">91d46819-8472-40ad-a661-2c78acb4018c:8594190</guid><dc:creator>dparys</dc:creator><slash:comments>0</slash:comments><comments>http://blogs.msdn.com/dparys/comments/8594190.aspx</comments><wfw:commentRss>http://blogs.msdn.com/dparys/commentrss.aspx?PostID=8594190</wfw:commentRss><wfw:comment>http://blogs.msdn.com/dparys/rsscomments.aspx?PostID=8594190</wfw:comment><description>&lt;p&gt;Seit Silverlight 2 Beta 2 draußen ist, kann ich endlich wieder an meinem Projekt weiterarbeiten. Ich schreibe eine kleine Anwendung die auf einen Datendienst zugreift, den ich mit den ADO.NET Data Services erstellt habe. Ich mußte feststellen das es drei wichtige Dinge zu beachten gilt:&lt;/p&gt;  &lt;p&gt;&lt;strong&gt;System.Data.Services.Client&lt;/strong&gt;&lt;/p&gt;  &lt;p&gt;Dieses Assembly ist verantwortlich für die Integration des Proxy Codes in das Silverlight Projekt. Es muß referenziert werden damit der erstellte Proxy mittels DataSvcUtil entsprechend funktioniert.&lt;/p&gt;  &lt;p&gt;&lt;strong&gt;Asynchrone Aufrufe&lt;/strong&gt;&lt;/p&gt;  &lt;p&gt;Möchte man nun auf Daten zugreifen, so muss dies immer asynchron geschehen. Synchrone Aufrufe werden in der aktuellen Beta nicht unterstützt.&lt;/p&gt;  &lt;p&gt;Versucht man synchron eine Abfrage gegen den Data Service mittels eines Proxies abzusetzen&lt;/p&gt;  &lt;div&gt;   &lt;div style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"&gt;     &lt;pre style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; margin: 0em; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"&gt;&lt;span style="color: #606060"&gt;   1:&lt;/span&gt; var query = from p &lt;span style="color: #0000ff"&gt;in&lt;/span&gt; ctx.Products&lt;/pre&gt;

&lt;/div&gt;

&lt;div&gt;&amp;#160;&lt;/div&gt;

&lt;div&gt;bekommt man eine &lt;em&gt;NotImplementedMethodException&lt;/em&gt; . Man muss auf jeden Fall asynchron arbeiten. Die eigentliche Abfrage muss explizit in ein &lt;em&gt;DataServiceQuery&amp;lt;T&amp;gt;&lt;/em&gt; umgewandelt werden. Folgender Code demonstriert die asynchrone Abfrage:&lt;/div&gt;

  &lt;/div&gt;
&lt;/div&gt;

&lt;div&gt;&amp;#160;&lt;/div&gt;

&lt;div&gt;&lt;strong&gt;ADO.NET Data Service im gleichen Projekt&lt;/strong&gt;&lt;/div&gt;

&lt;div&gt;&amp;#160;&lt;/div&gt;

&lt;div&gt;Was nirgends dokumentiert ist und vermutlich ein Bug ist (ich konnte es noch nicht genauer verifizieren), ist die Tatsache, dass in der jetzigen Beta der Data Service relativ angesprochen werden muss. Sprich, dieser sollte im gleichen Projekt wie das Silverlight Web Projekt liegen. Alles andere hat bei mir auf der Maschine nur einen Fehler beim Aufruf vom Invoke des Proxies ergeben (callOpen error). Um den Proxy mit der relativen URI zu instanzieren nutzt man einen entsprechenden Konstruktor:&lt;/div&gt;

&lt;div&gt;&amp;#160;&lt;/div&gt;

&lt;div&gt;
  &lt;div style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"&gt;
    &lt;pre style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; margin: 0em; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, &amp;#39;Courier New&amp;#39;, courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"&gt;&lt;span style="color: #606060"&gt;   1:&lt;/span&gt; var ctx = &lt;span style="color: #0000ff"&gt;new&lt;/span&gt; ModelEntitiesProxy( &lt;span style="color: #0000ff"&gt;new&lt;/span&gt; Uri( &lt;span style="color: #006080"&gt;&amp;quot;test.svc&amp;quot;&lt;/span&gt;, UriKind.Relative ) );&lt;/pre&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;div&gt;&amp;#160;&lt;/div&gt;

&lt;div&gt;Vielleicht gibt es ein Workaround für die absolute Adressierung, ausserhalb des Silverlight Web Projektes. Wenn jemand hier einen Link hat, ich wäre dankbar.&lt;/div&gt;

&lt;div&gt;&amp;#160;&lt;/div&gt;

&lt;div&gt;So, nun konnte ich das Projekt an den Service anbinden und mit den Daten arbeiten. Subjektiv gesehen ist die Performance nicht optimal zwischen dem Silverlight Projekt und dem Data Service. Es kommt mir träge vor, ist allerdings nur ein Subjektiver Eindruck, nicht durch Zahlen belegt. Abschliessend bleibt noch zu sagen, das die Beta durchaus für eine Evaluation eingesetzt werden kann, wobei man die Performance mal ausser Acht lassen sollte. Hier wird sich mit Sicherheit im Hinblick auf das Release noch was tun.&lt;/div&gt;&lt;img src="http://blogs.msdn.com/aggbug.aspx?PostID=8594190" width="1" height="1"&gt;</description><category domain="http://blogs.msdn.com/dparys/archive/tags/C_2300_/default.aspx">C#</category><category domain="http://blogs.msdn.com/dparys/archive/tags/.NET+Framework/default.aspx">.NET Framework</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Data+Access/default.aspx">Data Access</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Services/default.aspx">Services</category><category domain="http://blogs.msdn.com/dparys/archive/tags/LINQ/default.aspx">LINQ</category></item><item><title>Objekte mittels ADO.NET Data Services publizieren</title><link>http://blogs.msdn.com/dparys/archive/2008/06/06/objekte-mittels-ado-net-data-services-publizieren.aspx</link><pubDate>Fri, 06 Jun 2008 12:39:04 GMT</pubDate><guid isPermaLink="false">91d46819-8472-40ad-a661-2c78acb4018c:8577348</guid><dc:creator>dparys</dc:creator><slash:comments>2</slash:comments><comments>http://blogs.msdn.com/dparys/comments/8577348.aspx</comments><wfw:commentRss>http://blogs.msdn.com/dparys/commentrss.aspx?PostID=8577348</wfw:commentRss><wfw:comment>http://blogs.msdn.com/dparys/rsscomments.aspx?PostID=8577348</wfw:comment><description>&lt;p&gt;Die ADO.NET Data Services (ehemals Astoria) ist ein REST basierter Zugriffsdienst auf Daten. Daten werden im Form von ATOM oder JSON zur Verfügung gestellt und könen mit den HTTP Verben entsprechend modifziert und bearbeitet werden.&lt;/p&gt; &lt;p&gt;Ein Haupteinsatzszenario ist die Nutzung der ADO.NET Data Services um ein Entity Modell zu publizieren.&lt;/p&gt; &lt;div&gt; &lt;div style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, 'Courier New', courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"&gt;&lt;pre style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; margin: 0em; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, 'Courier New', courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"&gt;&lt;span style="color: #606060"&gt;   1:&lt;/span&gt; &lt;span style="color: #0000ff"&gt;public&lt;/span&gt; &lt;span style="color: #0000ff"&gt;class&lt;/span&gt; MyDataService : DataService&amp;lt; EntityModel &amp;gt;&lt;/pre&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;Doch was muss man eigentlich tun, um ein eigenes Objektmodell als ADO.NET Data Service zu veröffentlichen? Die Dokumentationen hierzu muss man sich mühselig aus verschiedenen Quellen zusammensuchen. Gerade die Dokumentation zu den ADO.NET Data Services in der VS 2008 SP1 Beta 1 ist wirklich nicht einfach zu finden. Googlen oder Liven bringt nichts, findet man nicht. Deshalb hier der Link:&lt;/p&gt;
&lt;p&gt;&lt;a title="http://vs2008sp1docs.msdn.microsoft.com/en-us/ms452029.aspx" href="http://vs2008sp1docs.msdn.microsoft.com/en-us/ms452029.aspx"&gt;http://vs2008sp1docs.msdn.microsoft.com/en-us/ms452029.aspx&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Auf MSDN Online gibt es noch zwei &lt;a href="http://msdn.microsoft.com/en-us/data/bb931106.aspx"&gt;weitere Dokumente&lt;/a&gt; für die ADO.NET Data Services, die allerdings noch mit den alten Objektmodell Namen arbeiten. Die Inhalte sind jedoch auch für das neue Release gültig. Um aber ein eigenes Datenmodell nicht nur lesend, sondern auch modifizierbar, über die Data Services zu publizieren muss man noch ein wichtiges Interface implementieren: &lt;em&gt;IUpdatable&lt;/em&gt;. Die Dokumentation hierzu ist in den folgendem Satz zusammengefasst:&lt;/p&gt;&lt;pre&gt;&lt;/pre&gt;
&lt;blockquote&gt;
&lt;h5&gt;&lt;em&gt;Write/Update Support&lt;/em&gt;&lt;/h5&gt;
&lt;p&gt;&lt;em&gt;To enable create, update, and delete support on a CLR data model, the class that models the top-level resource sets must implement the &lt;b&gt;IUpdatable&lt;/b&gt; interface. In reference to Example 2, CLR Objects to Astoria resources above, the &lt;b&gt;Accounting.DataModel&lt;/b&gt; class would be required to implement the &lt;b&gt;IUpdatable&lt;/b&gt; interface.&lt;/em&gt;&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&amp;lt;Sarkasmus&amp;gt;Exzellente Dokumtation!&amp;lt;/Sarkasmus&amp;gt;&lt;/p&gt;
&lt;p&gt;Ein bißchen mehr findet man dann doch noch auf dem &lt;a href="http://blogs.msdn.com/astoriateam/default.aspx"&gt;Astoria Blog&lt;/a&gt; – hier ist wenigstens noch die Interface Deklaration mit Kommentaren &lt;a href="http://blogs.msdn.com/astoriateam/archive/2008/04/10/iupdatable-ado-net-data-services-framework.aspx"&gt;gepostet&lt;/a&gt;. Nach Beispielen habe ich dann auch gar nicht mehr gesucht, wäre wohl auch Hoffnungslos.&lt;/p&gt;
&lt;p&gt;Trotz all dieser Probleme (wir sind ja in der Beta Phase) habe ich es dann doch noch geschafft mein kleines Beispiel-Objektmodell als Data Service mit Update Semantik zu publizieren. Im folgenden möchte ich einfach die Schritte zeigen, die ich durchlaufen bin, um das zu erreichen.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Das Objektmodell&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Mein Objektmodell bildet Spiele der kommenden Europameisterschaft 2008 ab. Es besteht aus einer Klasse (kann man dann überhaupt schon von einem Modell sprechen?), diese hat nur ein kleine Besonderheit:&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;DataServiceKey&lt;/em&gt;! Der &lt;em&gt;DataServiceKey&lt;/em&gt; deklariert einfach die Felder, an welchem das Objekt eindeutig zu identifizieren ist. In meinem Beispiel habe ich die Eigenschaft &lt;em&gt;MatchID &lt;/em&gt;als Schlüssel genommen. Genauso gut hätte ich auch die Spielpaarung selbst als Schlüssel wählen können, wie zum Beispiel &lt;em&gt;[DataServiceKey( “Home”, “Away” )]&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Allerdings muss man kombinierte Schlüssel auch dementsprechend in der URI angeben, insofern habe ich mich für eine kürzere Variante entschieden.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Zugriff auf Resourcen mittels URI&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Genau dieses Objekt möchte ich nun über dei ADO.NET Data Services addressierbar machen. Die URI sollte folgendermaßen aussehen:&lt;/p&gt;
&lt;p&gt;&lt;a href="http://localhost/Euro2008DataService.svc/Matches"&gt;http://localhost/Euro2008DataService.svc/Matches&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Um nun ein bestimmtes Match zu laden, gibt man nun einfach die Schlüssel des Objektes, in dem Beispiel also die &lt;em&gt;MatchID&lt;/em&gt; an. &lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="http://localhost/Euro2008DataService.svc/Matches(1"&gt;http://localhost/Euro2008DataService.svc/Matches(1&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Hätte ich nun als Schlüssel &lt;em&gt;Home&lt;/em&gt; und &lt;em&gt;Away&lt;/em&gt; definiert und möchte das Spiel Deutschland gegen Pole suchen, so würde der Zugriff folgendermaßen aussehen:&lt;/p&gt;
&lt;p&gt;&lt;a href="http://localhost/Euro2008DataService.svc/Matches(Away=&amp;rsquo;Poland&amp;rsquo;,Home=&amp;rsquo;Germany&amp;rsquo;"&gt;http://localhost/Euro2008DataService.svc/Matches(Away=’Poland’,Home=’Germany’&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Das eigene Data Model&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Die Defintion des Datenmodells fehlt uns, um das Match Objekt als Data Service Resource zur Verfügung zu stellen.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;IUpdatable implementieren&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Ein simpler WPF Client ist nun in der Lage die Daten zu visualisieren&lt;/p&gt;
&lt;p&gt;&lt;a href="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/Objektemittel.NETDataServicespublizieren_9C96/shot1_2.png"&gt;&lt;img title="shot1" style="border-right: 0px; border-top: 0px; border-left: 0px; border-bottom: 0px" height="355" alt="shot1" src="http://blogs.msdn.com/blogfiles/dparys/WindowsLiveWriter/Objektemittel.NETDataServicespublizieren_9C96/shot1_thumb.png" width="641" border="0"&gt;&lt;/a&gt; &lt;/p&gt;
&lt;p&gt;Damit der WPF Client nun auch die Ergebnisse nicht nur anzeigen, sondern auch anpassen kann, muss die Klasse &lt;em&gt;Euro2008DataModel&lt;/em&gt; noch das Interface &lt;em&gt;IUpdatable&lt;/em&gt; implementieren. Das Interface selbst hat einige Methoden, doch um nur die Aktualisierung der Ergebnisse für diese kleine Beispiel zu ermöglichen langen die folgenden:&lt;/p&gt;

&lt;p&gt;Die Methode &lt;em&gt;GetResource()&lt;/em&gt; gibt den Parameter &lt;em&gt;query&lt;/em&gt; vom Typ &lt;em&gt;IQueryable&lt;/em&gt; hinein. Hier würde unter Umständen noch ein Mapping auf einen anderen Queryprovider durchgeführt werden, in diesem Fall muss ich nichts tun. Der übergebene Query Provider ist genau der gleiche den ich für die interne Implementierung benutze um auf die Daten zuzugreifen. Ich kann hier folgende &lt;a href="http://msdn.microsoft.com/en-us/library/bb546158.aspx"&gt;Doku empfehlen&lt;/a&gt; die Erläutert wie man einen Provider implementiert und diesen entsprechend anpasst.&lt;/p&gt;
&lt;p&gt;Die Methode &lt;em&gt;SaveChanges()&lt;/em&gt; muss nichts machen, da bereits bei &lt;em&gt;SetValue()&lt;/em&gt; die Werte direkt in das Repository geschieben werden. Und wir erinnern uns, die Liste der Spiele wird im Speicher gehalten. Dementsprechend werden Properties auch gleich in das Original Objekt gesetzt. Hat man einen Datenbereich der Transaktionorientiert arbeitet oder mit einem Original – New-Value Ansatz, so würde man erst bei &lt;em&gt;SaveChanges()&lt;/em&gt; letztlich den Commit machen.&lt;/p&gt;
&lt;p&gt;Ist das neue Datenmodell publiziert, so kann man auch per WPF Client die Ergebnisse ein wenig anpassen, vielleicht ist das dann doch ein wenig realistischer…&lt;/p&gt;

Seit heute ist auch der &lt;a href="http://www.microsoft.com/germany/msdn/webcasts/library.aspx?id=1032372945"&gt;Webcast zu LINQ to Entities&lt;/a&gt; verf&amp;#252;gbar. LINQ to Entities ist noch der alte Name f&amp;#252;r diese Technologie, korrekterweise sollte ich das ganze ADO.NET Entity Framework nennen. Trotzdem habe ich es bei dem Titel belassen. Das ADO.NET Entity Framework ist momentan noch nicht final ver&amp;#246;ffentlicht und befindet sich noch in der Entwicklung. Ich habe diese &lt;a href="http://blogs.msdn.com/dparys/archive/2008/01/31/installation-des-ado-net-entity-framework-beta-3.aspx"&gt;Version&lt;/a&gt; f&amp;#252;r diesen Webcast benutzt. &lt;/p&gt;  &lt;p&gt;&lt;a href="http://www.microsoft.com/germany/msdn/webcasts/library.aspx?id=1032372945"&gt;Webcast LINQ to Entities&lt;/a&gt;&lt;/p&gt;&lt;img src="http://blogs.msdn.com/aggbug.aspx?PostID=8416060" width="1" height="1"&gt;</description><category domain="http://blogs.msdn.com/dparys/archive/tags/Webcasts/default.aspx">Webcasts</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Data+Access/default.aspx">Data Access</category><category domain="http://blogs.msdn.com/dparys/archive/tags/LINQ/default.aspx">LINQ</category></item><item><title>Webcast: LINQ to XML</title><link>http://blogs.msdn.com/dparys/archive/2008/04/22/webcast-linq-to-xml.aspx</link><pubDate>Tue, 22 Apr 2008 11:00:39 GMT</pubDate><guid isPermaLink="false">91d46819-8472-40ad-a661-2c78acb4018c:8416056</guid><dc:creator>dparys</dc:creator><slash:comments>1</slash:comments><comments>http://blogs.msdn.com/dparys/comments/8416056.aspx</comments><wfw:commentRss>http://blogs.msdn.com/dparys/commentrss.aspx?PostID=8416056</wfw:commentRss><wfw:comment>http://blogs.msdn.com/dparys/rsscomments.aspx?PostID=8416056</wfw:comment><description>&lt;p&gt;In der Reihe LINQ und Konsorten ist nun LINQ to XML verf&amp;#252;gbar.

W&amp;#228;hrend der Aufnahme zum dritten Teil habe ich nun auch endlich den Grund f&amp;#252;r die schlechte Audioqualit&amp;#228;t gefunden. Ich hatte den Codec vermutet, es war aber das Tool das ich zur Aufnahme und zum Encoden verwende: &lt;a href="http://www.techsmith.com/camtasia.asp"&gt;Camtasia&lt;/a&gt;. Camtasia ist ein gutes Produkt, leider werden einige Funktionen, darunter auch die Audiolevel Funktion, nur korrekt in ein Flash Video reinkodiert. Da ich es zu sp&amp;#228;t gemerkt habe, hat es eine Weile gedauert um die Qualit&amp;#228;t des Audios in der 3. Folge aufzuwerten, f&amp;#252;r Teil 4 bin ich nun gewappnet.&lt;/p&gt;&lt;img src="http://blogs.msdn.com/aggbug.aspx?PostID=8398791" width="1" height="1"&gt;</description><category domain="http://blogs.msdn.com/dparys/archive/tags/Webcasts/default.aspx">Webcasts</category><category domain="http://blogs.msdn.com/dparys/archive/tags/Data+Access/default.aspx">Data Access</category><category domain="http://blogs.msdn.com/dparys/archive/tags/LINQ/default.aspx">LINQ</category></item></channel></rss>
