Visual Studio 2008 doesn’t know a BizTalk project

If you have a new Visual Studio 2008 installation, or updated it in any way, you may find that adding a new BizTalk project will fail. The solution is simple: in the registry, change key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Projects\{FAE04EC0-301F-11d3-BF4B-00C04F79EFBC}] from ‘csproj’ to ‘csproj;btproj’. Somehow this key gets reset every time the Visual Studio installation is changed...


  1. I just did a repair with the BizTalk Setup, but this way would be much easier :), thanks.

  2. For the 64 bit version this would be following key by the way: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0\Projects\{FAE04EC0-301F-11d3-BF4B-00C04F79EFBC}
