在 Visual Studio 2019 中找不到“开始操作”

Question

I am a freshman at VS.

When I try to write a class library and find the debug configurations to change the "Start Action" but I can not find it.

So, somebody can teach me how can I do to make it visible.

Thank you all so much

Answer 1

You cannot start a class library because it is just a collection of functions. There is no starting point for the compiler to find.

Typically, to test a class library you would build a simple console application or even WinForms UI. These projects have a main method that can actually be run, and they can call methods in your library.

Just don't forget to add your library as a project reference. (Add -> Project Reference -> Library -> Ok)
