When I try to "Build" a project it says:
The operation could not be completed. Unspecified error
When I try to debug the debugger says:
The debugger cannot continue the process
I really don't understand what is wrong with that? The project is fine and it compiles perfectly on VS 2008.
Holy crap I didn't know that using "Terminal" as your output window font breaks the building/debugging process.
Without more context information it's hard to help. VC10 is in Beta2 state so you should report this problem with context (environement + projects infos) to the Microsoft Connect website.
