Not able to build C# 2010 .sln using VBP

[saurabh]

Hi,


I have configured the build for a .net C# 2010 project using VBP.
It was working fine till yesterday. But today I'm not able to build the project from Visual Build Pro (It works fine when I build from the VS2010 IDE). I get an error:

The selected file is a solution file, but was created by a newer version of this application and cannot be opened.

Please help me.

Thanks!
