I am running with a fresh installation of Visual Studio 2010 and Silverlight 4 in which Visual Studio tools are also involved. However, are running with the issues converting the Silverlight 3 projects into Silverlight 4. Visual Studio upgrades the Visual Studio 2008 solution and .NET3.5 projects without any issues but will not interchange the Silverlight Projects. It states that it is searching for "C:\Program Files\MSBuild\Microsoft\Silverlight v3.0\Microsoft.Silverlight.OurSolutionName.targets".
Followed that I don't have Silverlight 3 installed on such type of box and don't need to, how are we assumes to do this very conversion operation....NET4.0 conversion does not require for the .NET3.5 installation, so why does Silverlight 4 conversion?
