    I had the error code 8000000A, so it might be different, and I’m not sure if this is any help for your problem. But re-adding references did not work for me. However, what worked for me was removing the .suo file (next to the .sln) and (re)building again.

    (It might have been caused by accidentally opening a Visual Studio 2010 class library in a Visual Studio 2008 comapct project. I am not even going to try reproducing this!)

    Removing the .suo will make you ‘loose’ your open files (and maybe some other settings?), but IMHO that’s just a small sacrifice(?).

    I just hope this will save someone some time…
