I post a question in StackOverflow, but still no answer. http://stackoverflow.com/questions/25654538/after-git-vs2013-cannot-find-references-project-builds-and-runs-normally
After using git checkout several times, VS2013 cannot find references to other projects in same solution.
ReSharper shows many errors. However the project builds and runs normally.
I cloned the project again, but no changes. Clean and rebuild do not help.
How to fix it?
