我今天刚遇到此错误.我通过使用基础代码分支查看解决方案文件中的更改来修复此错误，并发现了一些原本不应该存在的旧行.我认为它们是错误合并的结果，应该在解决冲突时将其删除.

I just had this error today. I fixed this error by reviewing the changes in my solution file with our base code branch and found some old lines that weren't supposed to be there. I think they were a result of a bad merge and should have been removed during a conflict resolve.

要解决此问题，我只是删除了旧的引用，并且一切正常.

To fix the issue I simply removed the references that were old and everything built just fine.
