PowerCommands 1.1

ccBoy — Fri, 25 Apr 2008 08:57:22 GMT

如果你已经习惯了Coderush或Refactor! Pro的复杂和庞大，到时可以尝试一下 PowerCommands 1.1 for Visual Studio 2008
1.1版本包括下面的功能：

Enable/Disable PowerCommands in Options dialog
This feature allows you to select which commands to enable in the Visual Studio IDE. Point to the Tools menu, then click Options. Expand the PowerCommands options, then click Commands. Check the commands you would like to enable.
Note: All power commands are initially defaulted Enabled.
Format document on save / Remove and Sort Usings on save
The Format document on save option formats the tabs, spaces, and so on of the document being saved. It is equivalent to pointing to the Edit menu, clicking Advanced, and then clicking Format Document. The Remove and sort usings option removes unused using statements and sorts the remaining using statements in the document being saved.
Note: The Remove and sort usings option is only available for C# documents.
Note: Format document on save and Remove and sort usings both are initially defaulted OFF.
Clear All Panes
This command clears all output panes. It can be executed from the button on the toolbar of the Output window.
Copy Path
This command copies the full path of the currently selected item to the clipboard. It can be executed by right-clicking one of these nodes in the Solution Explorer:
The solution node; A project node; Any project item node; Any folder.
Email CodeSnippet
To email the lines of text you select in the code editor, right-click anywhere in the editor and then click Email CodeSnippet.
Insert Guid Attribute
This command adds a Guid attribute to a selected class. From the code editor, right-click anywhere within the class definition, then click Insert Guid Attribute.
Show All Files
This command shows the hidden files in all projects displayed in the Solution Explorer when the solution node is selected. It enhances the Show All Files button, which normally shows only the hidden files in the selected project node.
Undo Close
This command reopens a closed document , returning the cursor to its last position. To reopen the most recently closed document, point to the Edit menu, then click Undo Close. Alternately, you can use the CtrlShiftZ shortcut.
To reopen any other recently closed document, point to the View menu, click Other Windows, and then click Undo Close Window. The Undo Close window appears, typically next to the Output window. Double-click any document in the list to reopen it.
Collapse Projects
This command collapses a project or projects in the Solution Explorer starting from the root selected node. Collapsing a project can increase the readability of the solution. This command can be executed from three different places: solution, solution folders and project nodes respectively.
Copy Class
This command copies a selected class entire content to the clipboard, renaming the class. This command is normally followed by a Paste Class command, which renames the class to avoid a compilation error. It can be executed from a single project item or a project item with dependent sub items.
Paste Class
This command pastes a class entire content from the clipboard, renaming the class to avoid a compilation error. This command is normally preceded by a Copy Class command. It can be executed from a project or folder node.
Copy References
This command copies a reference or set of references to the clipboard. It can be executed from the references node, a single reference node or set of reference nodes.
Paste References
This command pastes a reference or set of references from the clipboard. It can be executed from different places depending on the type of project. For CSharp projects it can be executed from the references node. For Visual Basic and Website projects it can be executed from the project node.
Copy As Project Reference
This command copies a project as a project reference to the clipboard. It can be executed from a project node.
Edit Project File
This command opens the MSBuild project file for a selected project inside Visual Studio. It combines the existing Unload Project and Edit Project commands.
Open Containing Folder
This command opens a Windows Explorer window pointing to the physical path of a selected item. It can be executed from a project item node
Open Command Prompt
This command opens a Visual Studio command prompt pointing to the physical path of a selected item. It can be executed from four different places: solution, project, folder and project item nodes respectively.
Unload Projects
This command unloads all projects in a solution. This can be useful in MSBuild scenarios when multiple projects are being edited. This command can be executed from the solution node.
Reload Projects
This command reloads all unloaded projects in a solution. It can be executed from the solution node.
Remove and Sort Usings
This command removes and sort using statements for all classes given a project. It is useful, for example, in removing or organizing the using statements generated by a wizard. This command can be executed from a solution node or a single project node.
Extract Constant
This command creates a constant definition statement for a selected text. Extracting a constant effectively names a literal value, which can improve readability. This command can be executed from the code editor by right-clicking selected text.
Clear Recent File List
This command clears the Visual Studio recent file list. The Clear Recent File List command brings up a Clear File dialog which allows any or all recent files to be selected.
Clear Recent Project List
This command clears the Visual Studio recent project list. The Clear Recent Project List command brings up a Clear File dialog which allows any or all recent projects to be selected.
Transform Templates
This command executes a custom tool with associated text templates items. It can be executed from a DSL project node or a DSL folder node.
Close All
This command closes all documents. It can be executed from a document tab.

下一代技术平台-Oslo-- .NET FX 4.0, Biztalk 6, System Center 5,Visual Stuido 10.....

ccBoy — Wed, 31 Oct 2007 16:03:44 GMT

What is “Oslo”? What are the product and technology components that will be delivered?

“Oslo” is the latest in a series of long term investments in SOA and BPM technologies, enabling the development of distributed applications. At the conference, we will disclose the targeted investment areas and the associated priorities. These product investments are part of a multi-release investment that will help advance the Dynamic IT initiative – specifically in the areas of ‘services-enabled’ and ‘model-driven’.

There are five primary areas of investment targeted by “Oslo” development efforts:

Framework: The .NET Framework “4” release will make further investments in model-driven development as part of our Windows Communication Foundation (WCF) and Workflow Foundation (WF) technologies. This will be the logical successor to the .NET Framework 3.5 release happening later this calendar year.

Server: This release will continue to evolve our BizTalk family of products as the distributed platform for highly scalable SOA and BPM solutions. BizTalk Server “6” will build deeply on top of both WCF and WF as its core foundation, and deliver the capability to develop, manage and deploy composite applications.

Services: Extending the early BizTalk Services incubation (currently available at labs.biztalk.net), the BizTalk Services “1” release will deliver a commercial release of hosted services that enable cross-organizational composite application scenarios. This includes expanded capabilities around hosted messaging, identity and workflow capabilities.

Tools: These investments will advance the application lifecycle management capabilities of Visual Studio Team System and provide support for an expanded range of roles. Furthermore, Visual Studio “10” will provide deep support for model-driven design and deployment of composite applications.

Repository: There will also be investments aligning the metadata repositories across the Server and Tools product sets. System Center “5”, Visual Studio “10” and BizTalk Server “6” will utilize a common repository technology for managing, versioning, and deploying models.

The Vision: Significantly simplify the effort required to design, build, deploy and manage distributed applications within and across organizations.

从Oslo的Vision来看,这将是一个比较长期和穿越多个产品的技术组合和演进，也再次表明.NET技术和微软的产品从纵向开始交织，试图形成1+1>2的技术力量，更加切实的解决技术和平台如何穿越企业的流程、人员和组织。

另外这也将是一个非常不错的和最领先的视图，可以从中看到微软和.NET产品最新发展的计划和策略。

Messaging, Workflow Roadmap Announced

StockTrader - .NET 3.0 vs. Websphere 6.1

ccBoy — Sun, 12 Aug 2007 16:49:40 GMT

如果还记得2001年11月Microsoft .NET Pet Shop vs. Sun’s J2EE PetShop的例子和对比报表，今天微软又发布了一个示范案例.NET 3.0 的StockTrader应用，它相对应于IBM Trade 6.1示范应用，提供给.NET的开发人员示范和学习。

IBM Trade 6.1也是WebSphere 6.1性能测试的示范程序，用于证明WebSphere的性能，具体的信息和代码IBM也是公开的，你可以到IBM的网站下载

用.NET实现的StockTrader应用主要使用了ADO.NET 2.0, ASP.NET 2.0, WCF 和MSMQ 3.5/4.0等技术，而这次测试和性能评测集中在三个方面：

1. Web Services的性能

2. 消息处理的底层基础架构的性能

3. 数据访问和存取的速度

另外也从软硬件成本、代码行数、单位事务花费，配置文件和配置复杂性等进行了评估和对比。

这次测试的一个更重要的目的也验证了一种不同平台的互交互性，虽然双方平台不同，但因为都遵循目前开放和流行的Web Services协议，所以IBM Trade 6.1 Jsp前端也可以调用.NET StockTrader的中间层，同样.NET ASP.NET的前端也可以调用IBM Trade 6.1后端的EJB中间层。其操作只需要修改配置文件，而不用修改代码。

所以从这个角度上来说，.NET StockTrader没有使用所有的.NET 3.0的新技术，比如WF，WPF，AJAX….等技术。

有关事务的花费方面的对比，也是惊人的，每TPS的花费($/Cost per TPS )对比:

	.NET	WebSphere
Persistent Message Queue	$ 6.53	$ 134.69
Non-Persistent Message Queue	$ 5.24	$ 90.78

下面是有关Web Service的性能对比结论(报告的21页)

1. Both the ASMX and WCF SOAP/HTTP configurations are significantly faster than IBM WebSphere 6.1 for hosting Web Services. .NET WCF hosted in IIS offers 46% better throughput than the JDBC WebSphere configuration in this test; and 124% better throughput than the EJB implementation.

2. Self-hosting WCF services can lead to performance advantages over hosting .NET Web Services in IIS—even when operating over an HTTP-XML basicHttpBinding. Self hosted WCF HTTP Web Services offer 56% better throughout than the ASMX equivalent services hosted in IIS for this test. They offer 45% better throughput than the equivalent WCF IIS-hosted service operating over Http-XML.

3. Self hosted Web Services using WCF significantly outperform IBM WebSphere Web Services. The self-hosted WCF services operating over Http-XML (full SOAP compliance) offer 113% better throughput than the fastest WebSphere Web Service results (JDBC data access). They offer 225% better throughout than the WebSphere Web Services using EJB entity bean database access.

4. The self-hosted WCF services can also support, simultaneously, the netTcp WCF binding, with binary encoding. This can lead to significant performance boosts for remote calls. The WCF netTcpBinding replaces .NET Binary Remoting (used with .NET 1.1 and 2.0) as the preferred way for remote calls between .NET clients and remote .NET services. Supporting both HTTP/XML and TCP/Binary requires no extra development, as WCF unifies the programming model for HTTP-based Web Services and .NET Binary-remoted components, and service hosts will listen simultaneously on all configured endpoints to support any different type of client on any platform.

5. The Tcp-Binary binding (netTcpBinding) between the ASP.NET clients and the Web Service host offer 81% better throughput than the WCF basicHttpBinding used in the same self-host .NET executable. The Tcp-Binary remote mode offers 284% better throughput than the fastest WebSphere Web Service configuration (JDBC data access).
