We get the above error message on our build server, when we build the solution or the specific project that the error refers to.
We can build the solution without any problem using visual studio (also on the build server), however it fails with the above error when running msbuild.
Any Ideas?
I found the solution.
There is a "bug" in msbuild, that results in it failing when there are not source files in the project. For example Filename.cs.
Our project only had xml and other file types.
Just added an empty cs file and it worked.
