不知道出了什么问题，但是要修复它，我不得不删除.sln文件和.csproj文件，然后再次从TFS中获取它们，以使其正常工作.不知道他们出了什么问题，但这是可行的.感谢您的帮助！

原来，该方法只能使用少量时间.似乎使它起作用(至少在最后一个小时内)的原因是，将IIS中的最大工作进程"的数目改回了1.

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 :/
