I'm using VS2008 SP1 - don't know if this would have happened before I applied SP1 as I never tried it before yesterday. I attempted to debug a fairly simple XSLT file using VS2008 SP1 and got this crash from VS2008 SP1:
Microsoft Visual Studio
Unexpected error encountered. It is recommended that you restart the application as soon as possible.
Error: Unspecified error
File: vsee\pkgs\vssprovider\sccprj.cpp
We have reproduced this issue and will fix it in the next release of Visual Studio.
