  • Blog Post: Parallele Programmierung mit PLINQ und .NET 4.0

    Mit Hilfe der bei .NET 4.0 integrierten Task Parallel Library und deren Erweiterungsmethoden lassen sich auch LINQ-Abfragen einfach parallel ausführen.

  • Blog Post: Composable LINQ to SQL query with dynamic OrderBy

    It is a pretty common need to be able to compose a query with multiple "where" parameters at runtime. There are are scenarios where you want to pass multiple unrelated parameters for your selection that user will chose only at runtime. Lets take an example. In our HOL for Silverlight http://blogs...

  • Blog Post: Parallel Programming

    Zur Frage wo in den nächsten Jahren die grosse Investitionen innerhalb der Software Entwicklung stattfinden werden, denke ich, dass sehr viel im Bereich Parallel Programming gemacht wird. Microsoft ist natürlich auch davon betroffen und wird Parallel-Unterstützung innerhalb dem .NET Framework integrieren...

  • Blog Post: LINQ to Everything …

    Charlie Calvert’s is holding a nice Links to LINQ page where he has grouped a list of useful resources. So, if you are working or planning to work with LINQ have a look at this page where you also get a list of LINQ providers that allow you to use LINQ with a variety of source of information like LINQ...
  • Blog Post: LINQ to SQL and LINQ to Entities providers

    Yesterday, during the TechDays in Geneva, I met quite a lot of people asking about the availability of LINQ to SQL providers for databases other than SQL Server. Unluckily, at least from Microsoft side, nothing has been announced yet (third parties neither) and I don’t think it will happens. On...
  • Blog Post: LINQ to SQL: returning multiple result sets

    As you probably know LINQ to SQL supports stored procedure (SP). You can drag&drop a SP in the LINQ to SQL Designer and the magic happens: a new method inside the DataContext class is generated and a new return type is defined by the designer to represent this result (the name of the type is composed...

  • Blog Post: Using your own defined type in a LINQ query expression

    One of the great features of C# 3.0 are anonymous types. Anonymous Types enable developers to concisely define inline CLR types within code, without having to explicitly define a formal class declaration of the type. In C# the definition of an anonymous type makes use of another C# 3.0 new feature: the...
  • Blog Post: LINQ to SQL: the good, the bad and the ugly

    Let’s start with the good : I was never a big fan of O/R mapping technology nor to do all the work by hand in populating objects. So I tend to chose typed DataSet in project where the speed of development is a key driver. Of course DataSets are big on the wire and .NET only, so it is not the right...

  • Blog Post: From Anonymous Types to Lambda Expression (Sample)

    I decided to post a short sample taken from the C# 3.0 Enhancements & LINQ HOL I hold last week. C# 2.0 introduced the concept of anonymous methods, which allow code blocks to be written “in-line” where delegate values are expected. Lambda Expressions provide a more concise, functional syntax...

  • Blog Post: Worin besteht der Unterschied zwischen LINQ to SQL und LINQ to Entities?

    LINQ to SQL ist im Prinzip eine ORM (Object Relational Mapping) Implementierung, die Ihnen erlaubt eine SQL Server Datenbank als .NET Objekte zu modellieren. Diese Modellierung, die einem Object einer Tabelle entspricht, kann mit Hilfe eines LINQ to SQL Designers (Teil von Visual Studio 2008) gemacht...
