visual-studio - Visual Studio 2015 : An equivalent project is already present in the project collection

Question

尝试将现有项目重新添加到 Visual Studio 2015 解决方案时，VS 会提供以下错误消息。我已确认我尚未添加对要添加的项目的引用。是否有我需要在某处删除或清理的设置或缓存文件？

An equivalent project (a project with the same global properties and tools version) is already present in the project collection, with the path "D:\My\Path\MyProject.csproj". To load an equivalent into this project collection, unload this project first.

简单的“清洁解决方案”对我有用。
