Silverlight Tools Must be Updated After Installing Visual Studio 2008 SP1

Today, Visual Studio 2008 Service Pack 1 was released.  This service pack includes support for SQL Server 2008, new ADO.NET features such as the Entity Framework, improvements to the WPF designers, WCF templates for Silverlight projects, debugger support for the .NET Framework public symbols and source release, control improvements such as the DataRepeater for Windows Forms and Office 2007 Ribbons for C++, and several general updates for debugging and IntelliSense. SP1 also enhances the stability, performance, and security of many features.

If you previously had Silverlight Tools Beta 2 installed, after installing SP1, if you open or create a Silverlight project, a dialog will open stating:  Microsoft Silverlight Tools is unable to open the project due to a missing patch for Visual Studio. Please download the latest update from: https://go.microsoft.com/fwlink/?LinkID=120032 .

An updated patch that works with Visual Studio SP1 is included in the Silverlight Tools install at https://go.microsoft.com/fwlink/?LinkID=120032.  Once installed, Visual Studio will once again be able to open and create Silverlight projects.

UPDATED: Some users have experienced issues with downloading a cached version of the tools installer.  The download should be signed on 8/1/2008 and should install KB955214.  I am currently working with our download center to resolve the caching issue.  In the meantime, the correct version of the installer is available here (as with any .exe you download from the Internet, verify that it was digitally signed by a trusted source before installing).  If you continue to see this dialog after the update, please contact me. 

Note For Non-English Users of Silverlight Tools

An updated version of Silverlight Tools available in 8 additional laguages will be published shortly following the English release.  Before installing Visual Studio 2008 SP1, please visit https://go.microsoft.com/fwlink/?LinkID=120032 to confirm that an update for Silverlight Tools is available in your language.

What's Different About This Silverlight Tools Installer?

This installer has been updated to include a new patch that works specifically with the final version of SP1.  Previously, the installer had worked with SP1 Beta.  SP1 Beta is no longer supported by Silverlight Tools. 

Silverlight Tools Beta 2 currently supports Visual Studio 2008 (Standard or higher) RTM and Visual Studio 2008 (Standard or higher) SP1.  The final version of Silverlight Tools will support Visual Studio 2008 SP1 - Express, Standard, Professional, and Team System. 

What Other Issues Might I Encounter with VS 2008 SP1 and Silverlight Tools?

SP1 will not install if you currently have Silverlight Tools Beta 1 installed (instead of Silverlight Tools Beta 2).  For help or more information on removing Silverlight Tools Beta 1, visit: https://blogs.msdn.com/webdevtools/archive/2008/05/12/error-installing-visual-studio-2008-sp1-beta-and-silverlight-tools-beta-1.aspx 

Neither SP1 nor Silverlight Tools will install if previous installations (especially VS 2008 SP1 Beta and Silverlight Tools Beta 1) have resulted in incompatible DLLs.  For more information on this, visit: https://silverlight.net/GetStarted/SP1InstallInfo/ 

The updated installer for Silverlight Tools will not install on Visual Studio SP1 Beta or RC.  You must upgrade to the final version of Visual Studio 2008 SP1 before updating Silverlight Tools.  Visual Studio SP1 can be downloaded at: https://go.microsoft.com/fwlink/?LinkId=122094.

Silverlight Tools is available in 9 languages (English, Japanese, Spanish, French, German, Italian, Korean, Chinese - simplified, and Chinese-traditional).  The language version you select for Silverlight Tools must match the language of your Visual Studio installation.  All language versions for Silverlight Tools can be found at https://go.microsoft.com/fwlink/?LinkId=120319.
