I am working with C# Windows application . I've recently converted a Visual Studio 2008 project to the new Visual Studio 2012 project . Now I have to downgrade this project to Visual Studio 2008 . Is there any way to downgrade this project?

Well 2012 is compatible with 2010, i am not sure this would work but i found this on how to go back from 2010 to 2008, hope it works for you with 2012 (Original Link):

1. Make back up of your .sln file

2. Open your VS 2010 .sln in notepad.

   It should look something like this:

   Microsoft Visual Studio Solution File, Format Version 11.00 
   # Visual Studio 2010  Project("{FAE04EC0-3 ......
   

3. Change the Version 11.0 to Version 10.0 and the Visual Studio 2010 to 2008

   It should look something like this:

   Microsoft Visual Studio Solution File, Format Version 10.00 
   # Visual Studio 2008  Project("{FAE04EC0-3 .....
