Hi Jason,
Thanks for the post. Just had the same problem with VS2013.
Seemed to be caused by running VS2013 when Windows had only done a partial update (without telling me).
Unfortunately, it looks like an Uninstall/reinstall is needed. And a days worth of work lost.
Hello,
My case happened when I installed Microsoft Windows Azure SDK. The install went well except Azure Storage Emulator.
I cleared the cache the problem went out. Delete all files in the folder and reopen the VS
For VS2012:
%LOCALAPPDATA%\Microsoft\VisualStudio\11.0\ComponentModelCache
For VS2013:
%LOCALAPPDATA%\Microsoft\VisualStudio\12.0\ComponentModelCache
Nice day,
