Final Release of Silverlight 4 Tools for Visual Studio 2010 is Now Available

We are delighted to announce that the final release of Silverlight 4 Tools for Visual Studio 2010 is now available!

What is in the Silverlight 4 Tools for Visual Studio 2010?

Silverlight 4 Tools for VS 2010 includes many essential features to help you work with your Silverlight 4 application:

  • Support for targeting Silverlight 4 in the Silverlight designer and project system

  • RIA Services application templates and libraries to simplify access to your data services (check out this video and whitepaper giving full details)

  • Support for Silverlight 4 elevated trust and out-of-browser applications

  • Go To Value Definition lets you navigate directly from controls on your page to the styles that are applied to them. This means you can quickly and easily figure out and work with the style and resource structures in your application, and finally understand for sure "why that button on your app is red":



    The command will take you right to the XAML where the Style is defined, and you can easily navigate onward from there to any referenced resources, as long as the design pane is activated. This works for all kinds of Style.

  • Style Intellisense lets you easily modify styles you already have in XAML; now you get intellisense for properties and their values within a style based on the TargetType:

  • Drag and drop from the data source window and see the Data Source Selector, from which you can easily select and modify your data source information:

  • Add, remove, and re-sort DSW outputs using the Grid Row and Column context menu

    This feature works well for re-ordering and making space for new features in any Grid-based layout too.

  • Move your controls around the form and change alignments in bulk using the Thickness Editor for editing Margins, Padding etc

  • 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 via the Data Binding Picker, it also means you can design size-to-content/auto layouts much more smoothly. The design time data will flow cleanly between Visual Studio and Expression Blend too.


  • Working with Silverlight 4 Out-of-browser applications

    • Automatically launch and debug your OOB app from inside the IDE
    • Specify XAP signing for trusted OOB apps
    • Set the OOB window characteristics
