I have one project with .net framework 3.5, now i need to downgrade the framework version to 2.0.
But i can not find how to do this in Visual Studio 2008.
So i found this:
find your projectname.csproj, open it with text editor and find:
change it to 2.0 and open the project, fix the compile error. Easy.....
About how to roll back from VS2008 project to VS2005 project, refer to please:
