Hello, did you check Brenden's answer on stackoverflow thread you've started?
I've added a suggestion for you there as well.
This is typically caused by your .sln file having an unsupported path reference to your project files. Your best bet is to open up your .sln with a text editor and check those paths. They need to be physical directory paths and not other kinds. I've had this happen a lot.
