Every time I try to debug one of my apps I get the below error message. Anyone have any ideas? I tried running Visual Studio in safe mode but I get the same thing. I also tried to repair the install and completely reinstall it with no luck :(. The full Problem Signature is this:

Not sure what was wrong but to fix it I had to delete the .sln files and the .csproj files and get them from TFS again for it to work. Don't know what was wrong with them but that worked. Thanks for your help guys!

Edit:

Above turned out to only work for a small amount of time. What seems to have made it work (for the last hour at least) was changing the number of Maximum Worker Processes in IIS back down to 1. Completely lost on why this worked :/
