I'm trying to build a project that wasn't created by me. VS gives me the error:
Could not write lines to file "obj\Debug\C:\...". The given path's format is not supported.
I've replaced the full path with "...". Note that the path is interrupted with "C:\...".
Does anyone know what VS uses to form this path and where I might be able to change it? The file type that it is trying to write is .csprojccrefgen.rsp.
It turns out it was due to an invalid installation of the Code Contracts for .NET plugin for VS. I had to install the latest version from here, which resolved the issue.
