I have Visual Studio 2010 SP1.
I wrongly edit and save the file
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets
and now I can't compile anymore. The error I got is
1>C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.Targets(767,39): error MSB4057: The target "_Xsd" does not exist in the project.
I reinstalled Visual Studio 2010, I copied the file from another computer but nothing works and I still have the same error. What can I do?
