Creating a virtual directory failed with the error

Question

I can\'t solve this problem

I suggest I have to change c:\\Windo

Answer 1

More often than not, at least in my case, this happens is when a *.csproj.user file is in the project directory and has true in it.

Alternatively, as mentioned by Zachary Cutler you can also simply: close Visual Studio, delete the *.csproj.user file and reopen Visual Studio. This will force VS to rebuild the file.
