C # modify the default icon of the winform EXE Application

When using C # For winform development, the app icons that come with DOTNET are really not nice, and it feels like an error file. Now I want to add an image to my application to make it look better.

The method is as follows:

On Solution Explorer, right-click the project name-properties-click the icon and click the button on the right of the List to go To the debug folder and find your own icon. Save the settings.

Press F5 and run it. Then, go to the debug folder to see if your application icon is the one you just selected.
