推荐答案

这是因为您的应用程序将其命名为Windows服务。此应用程序类型不是交互式的。但有些奇怪的原因，你决定可以使用UI，但你根本不能。它没有任何意义：服务应该在您注销时运行，此时桌面在哪里。



忘掉用户界面。

This is because your application type it the Windows Service. This application type is not interactive. But some weird reason, you decided that you can use UI with it, but you simply cannot. And it would not make any sense: the service should be running when you log out, and where is the desktop at this time.

Just forget about UI.
