Answer 1

Have you enabled "Unmanaged code debugging"?

See this link:

Did you upgrade to .NET 4.5? It appears that can cause issues.

Unable to launch SOS.dll using VS 2010

I know in WinDBG you can issue this command:

.loadby sos clr

This causes it to load the sos.dll that is in the same directory as the clr.
