Answer 1

I had this same issue but it was the result of copying a solution from my local development computer to a networked drive where we store our projects. I was unable to get the reference to work properly when I opened the solution from a mapped drive and I kept receiving this error. Only temporary workaround I found for my specific issue was to open the solution from its UNC path and not the mapped drive letter.
