I found this utility in sourceforge.DescriptionCVSVC is Windows utility for converting between Visual Studio 2010 Forms Project to 2008 version İts supports only Visual Studio 2010Visual Studio Converter 2010 to 2008[^]
alternatively you can use the SolutionConverter here from code project. The tool converts 2008 to 2010 and vice versa. The only limitation is that it don't support C++ projects.
Another very simple way is to use SharpDevelop which will downgrade/upgrade and sidegrade (change between .NET versions).
Instead, you can create a new project in VS2008 and add the source code files to it.
