I’m running into a similar issue in the Reunion 0.5 release. When pressing Debug in Visual Studio I get the UAC dialog, but after allowing that nothing happens (the debugger still seems to be attached though). But if I press “Break All” button it says “No processes are currently being debugged”, so it’s most likely crashed.
