Answer 1

Right click in Solution Explorer on your Project's References entry and click on Add Reference...

Make sure you're looking under Assemblies --> Framework, then find and check the checkbox for System.Drawing , then click OK.

From here, you can use System.Drawing.Point in your code.

Answer 2

As others have indicated, you are missing a reference to System.Drawing in your project. The reason this works in some project types and not others is that some project types, specifically Windows Forms projects, will automatically add the reference to System.Drawing for you. While other project types like Console App, Class Library, or WPF Application do not automatically have that reference, so you have to manually add it.
