推荐答案

您无法将任何生成类库的项目设置为VS中的启动项目：产品DLL文件而不是EXE，并且不包含系统运行应用程序所需的Main方法。



通过右键单击解决方案资源管理器中的名称，将可执行项目设置为启动项目。

You cannot set any project that generates a class library as the Startup Project in VS: the produce DLL files rather than EXE and do not contain a Main method which the system needs in order to run an application.

Set an executable project as your Startup Project by right clicking it's name in the Solution Explorer.
