• • Microsoft .NET Framework 4
  • Microsoft Visual Studio 2010 or Microsoft Visual Web Developer 2010 Express Edition
  • Microsoft Silverlight 4 SDK and Microsoft Silverlight Tools for Visual Studio 2010 (both optional)

• Download and run the installer to put WCF Data Services 5.0 on your computer.
  
  • Please make sure Visual Studio is closed before running the installer.
  • This is a side-by-side release with the assemblies shipped with .NET Framework 4 and Silverlight 4.
  • The WCF Data Services 5.0 installer will update the "Add Service Reference" tooling integration in Visual Studio 2010 if it’s already installed, hence it will generate code based on WCF Data Services 5.0.
  • The KB2502836 update for Visual Studio 2010 and Visual Web Developer (that gets delivered as a part of this update for Silverlight 5 development) reverts the "Add Service Reference" behavior to generate code based on the assemblies that shipped in the .NET Framework 4. Running the WCF Data Services Installer and repairing the installation fixes this problem.
