我将ASP.NET Web应用程序更改为使用本地IIS,而不是IIS Express.现在重新打开解决方案后,加载应用程序时会出现以下错误：
error : Project ‘Atlas2’ could not be opened because the Visual C# 2015 compiler could not be created. ‘Atlas2’ is already part of the workspace.
error : Project ‘Atlas2’ could not be opened because the Visual C#
2015 compiler could not be created. An item with the same key has
already been added.
有人可以帮助我如何重新加载项目？
我正在使用Visual Studio Team Services(TFS Online),如果有帮助的话.
