c# - A file or folder with the name already exists when unit test project added

Question

Large edit to make this more appropriate than "VS has a bug" complaint.

If I add a unit test project to my VS2012 solution, I can't add any item at all to any project in the solution. VS complains that another file or folder with that name, whatever name I choose, already exists. I also cannot add existing items to projects.

If I remove the unit test project, problem goes away. Does anyone know about some dumb way I set up my solution to trigger this problem?

由于我无法在 VS2013 中重现这一点，而且 VS2012 现在已经完全老了，我会说一个“可接受的”解决方案（希望不是唯一的）是升级。感谢大家的帮助。
