Hi,
I've been following this thread with great interest, and I seem to have found a possible answer.
I too, have this problem, and I have narrowed it down to the fact, that the solution contains setup-projects.
When removing the setup project(s), the WMDebugger runs as expected.
If the setup projects are included in the solution, the beformentioned error occors.
Hope this helps.
