Help getting a debug environment setup.

[ChrisG]

Rainer, thanks for the reply. Based on your suggestion I started 
yanking extensions our of Visual Studio until I thought I'd 
broken it totally. I have a ton of stuff installed (...you don't 
want to know). Looks like I had a bad extension 
"Microsoft.DriverKit.DriverTestPackage" (from the WDK... I 
think?) that was interacting poorly with the Visual D plugin.

BTW, if anyone else experiences the same problem, I couldn't seem 
to fix it by just uninstalling the WDK. I ended up having to 
manually delete this registry key to fix it: 
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\Packages\{18B934DB-9F52-4F48-A988-B3325DD23A4B}

Debugging hot-keys work now. Thanks.
