title: Visual Studio 2008 marks solution files as version 10.00
body: <p>After trying out VS2010b2 also my VS2008 installation changes the versions of solution and project files to "Version 10.00". The MSBuild.exe on our CI Server does not support them.
  Is there a way to make VS2008 generate .sln files with version number 9.00 again?</p>
  
  <p>I know I can fix that manually. But each time I open a solution, the version gets changed back, which is annoying.</p>
  
  <p>Cheers,</p>
