After refactoring some code, my webnodes installation suddenly stopped working (after successfully running all Unit Tests).
I have not touched IIS settings, web.config or global.asax.
I have restarted IIS and Sqlserver. I have also deleted temp asp.net files (in c:\Windows\Microsoft.Net). I have also deleted \WAF\Files\Temp.
Accessing /edit produces the same error.
My entire Solution compiles fine, and the Webnodes site is verified without any problems.
I also get the same error when I attempt to ensure basic data / rebuild code files.
Does anyone have an idea on how to get it working again? :)
