Error when i'm trying to open VS 2012 project in VS 2010


Tried with the below approach, it worked out. But i'm not sure this is a best way to do.Take a risk, do it..





  • Just open the solution in a text editor 
  • in the second line you can find Microsoft Visual Studio Solution File, 
  • Format Version 12.00 
  • Try to open the solution and it works.
  • change the version to 11.00 and save it.


Keep ur coding aside.. Relax for some time..
