Description

After installing the VS11 Developer Preview and .NET 4.5 on my developer machine that has VS 2010, my Error List is clogged with bogus compilation errors. I can build with no errors, but a fraction of a second later my error window fills with bogus errors related to types that are being imported via project references.

I believe this can be closed. I think what happened is that the newer versions of msbuild.exe and csc.exe exposed a problem in our .sln file where we had not called out some explicit dependencies between projects. For example project B taking a binary reference to project A, but our .sln didn't have the explicit dependency captured in the the "Project Dependencies... " dialog. Somehow we were getting lucky with the .Net 4.0 version of the tools, but the flaw is clearly ours.

I apologize for the noise. Thanks for looking into this.

I missed the first request for a sample, sorry. I will work on a smaller repo, currently seeing it in a .sln file with 45+ projects.
