Your project is a user control library project. You are running that project in debug mode. As a user control library project cannot actually run as an application it opens the screen you see. This allows you to test the user controls in your project. You select your user controls from the drop down and can change properties from the property grid.

If you look at your solution explorer you will see that your user control project is listed in Bold text:

This means that the control library is the default project that will run when you press the debug button.

To change this, right click on your windows forms application project and select Set as StartUp Project from the list.

Your windows forms project will now be shown in Bold text:

Now, when you start debugging the solution it will run the Windows Forms Application instead of the User Control Library.
