Silverlight 4 support

Microsoft Silverlight 4 Tools for Visual Studio 2010 is included in Visual Studio 2010 SP1. This adds support for targeting Silverlight 4 in the Silverlight designer and project system. This also provides support for the new Silverlight 4 technology improvements. This new technology includes working with implicit styles and Silverlight 4 Out-of-Browser (OOB) applications. You can automatically start and debug your OOB application from inside the IDE, specify XAP signing for trusted OOB applications, and set the OOB window characteristics.

Basic Unit Testing support for the .NET Framework 3.5

In Visual Studio 2010 SP1, you now have the functionality to test your applications that target the .NET Framework 3.5. For more information about how to enable this functionality, see the following MSDN blog:

Amit Chatterjee's .NET 3.5 Unit Testing discussion

Performance Wizard for Silverlight

Visual Studio 2010 SP1 enables you to tune the Silverlight application performance by profiling the code. A traditional code profiler cannot tune the rendering performance for Silverlight applications. Many higher-level profilers are added to Visual Studio 2010 SP1 so that you can better determine which parts of the application consume time.

IntelliTrace for 64-bit and SharePoint

IntelliTrace is the revolutionary new debugging technology in Visual Studio 2010 that enables you to move forward and backward through a debug session. However, because of time constraints and because it is a completely new feature, this technology does not work in all scenarios.

Visual Studio 2010 SP1 enables the IntelliTrace debugging technology on 64-bit solutions and for Microsoft SharePoint farm solutions.

Software rendering

By default, software rendering is enabled on Windows XP and on Windows Server 2003 to help improve the performance and stability of Visual Studio 2010.

Detecting mixed-mode installations

If you install multiple versions of Visual Studio 2010 on the same computer, a combination of program binaries may run in the same instance of Visual Studio. For example, this issue occurs when you have the release version of Visual Studio 2010 Ultimate installed on the same computer where you have Microsoft Visual Basic Express Service Pack 1 installed. This kind of installation may cause stability or functional issues. Visual Studio 2010 SP1 detects whether the installation of SP1 is complete and may prompt you to update it if the installation is incomplete. This makes sure that the installation is in a known, stable state.

IIS Express support

Visual Studio 2010 SP1 enables you to use the Internet Information Services (IIS) 7.5 Express as the local hosting server for the website and Web Application Projects.

Note IIS 7.5 Express is not included in SP1, and you must download it separately. For more information, visit the following blog:

http://weblogs.asp.net/scottgu/archive/2011/01/03/vs-2010-sp1-beta-and-iis-developer-express.aspx

SQL Server CE 4 support

Visual Studio 2010 SP1 enables you to manage Microsoft SQL Server Compact 4.0 SDF files in Solution Explorer and in Server Explorer in the context of web projects. Additionally, Visual Studio 2010 SP1 enables you to use SQL Server Compact 4.0 together with the Microsoft ASP.NET Web Forms in a SQL data source control.

Note SQL Server Compact 4.0 is not included in Visual Studio 2010 SP1, and you must download it separately. For more information, visit the following blog:

VS 2010 SP1 and SQL CE

Razor support

Changes are made to the web project systems and to the HTML editor to support the new Razor syntax. This new syntax is used by ASP.NET Web Pages and by ASP.NET MVC 3.

Note Razor is not included in SP1, and you must download it separately. For more information, visit the following blogs:

Introducing “Razor” – a new view engine for ASP.NET

How to get Razor syntax support in Visual Studio 2010
 

Web PI integration

Support for the Microsoft Web Platform Installer (PI) is added in Visual Studio 2010 SP1 as follows:

• A new toolbar is added that allows for quick access to start the latest version of Web PI. Additionally, if the Web PI was not installed, it is downloaded first.

• When you open web projects that use IIS 7.5 Express, SQL Server Compact 4.0, or ASP.NET Razor syntax, a dialog box appears that offers to download and install these components by using Web PI if the components are not already installed.

Deployable dependencies

Some new technology components that are added in Visual Studio 2010 SP1 can be bin-deployed together with an application. Then, you can use the components even when you deploy the application to a server on which those components are not installed. A new dialog box is added in Visual Studio 2010 SP1 that makes it easier to add these deployable dependencies to the web project. To access the dialog box, right-click the project in Solution Explorer, and then select Add Deployable Dependencies. The following components are supported:

• ASP.NET Web Pages that use Razor Syntax

• SQL Server Compact 4.0

• ASP.NET MVC 3

For more information, visit the following blogs:

HTML5 and CSS3 support

Preliminary support is added for HTML5 to the HTML editor so that you can obtain IntelliSense and validation for HTML elements and attributes. A complete version that brings a fuller HTML5 experience will be provided in a future version of Visual Studio. For more information, visit the following blog:

HTML5 & CSS3 in Visual Studio 2010 SP1

WCF RIA Services V1 SP1 included

The WCF RIA service is now localized in 10 different languages that are supported by Visual Studio 2010 SP1. An entity may now contain members of a complex type. For example, you can use the Customer.Address type where Customer is an entity, but Address is not an entity. An entity type may now be used in multiple DomainService classes in the same application. The restriction on how to use a given entity type inside at most one DomainService is lifted. A code generation extensibility point is now publicly available. It may be used for T4-based and other code-generators that are external to the product. Additionally, DataForm Add/Remove operations are now enabled for the EntitySet class and the EntityCollection class.

Style IntelliSense

Lets you easily modify styles that you already have in XAML. Now you get IntelliSense for properties and their values in a style that is based on the TargetType.

Data source selector

Lets you easily select and modify the data source information directly from the design surface.

Advanced grid commands

Lets you easily add, remove, and reorder grid rows and columns.

New Thickness Editor

Lets you bulk edit specific items such as margins or padding on multiple controls.

Sample data support

Lets you add sample data to see your item templates and bindings light up at design time. Not only does this make hooking up data bindings easier through the Data Binding Picker, it also means that you can design size-to-content and auto layouts much more smoothly. Also, the design time data will flow cleanly between Visual Studio and Expression Blend.

• A test run stops responding when the QTAgent fails to start or the test run stops responding in the Main() function.

• The TestContext output is incorrect for inner tests that are contained inside an Ordered test.

• A performance issue occurs when a test is loaded in test controller.

• Running large amount of tests on a lab environment leaves some tests in the "Not Executed" state.

• Code coloring for code coverage is not working for unmanaged C++ code.

• The TestCaseId property comes out to be the same for all test cases that are associated with the same test method.

TCM Server

• The warehouse rebuild takes longer than expected to finish.

• Resetting automated test results can cause two changes of a point to appear in the warehouse as the current version.

Microsoft Test Manager

• The "Configure Diagnostic Data Adapter-Event Log" page is truncated in different language versions of Microsoft Test Manager.

• Analyzing test results causes the result to become the most recent result in the test point trend.
