System.Drawing.Point represents a GDI point and is used in Windows Forms. It can only hold integer values.

WPF doesn't use GDI anymore, so it has its own System.Windows.Point type to represents a point, which can have non integer values.

One is used with the classes in System.Drawing namespaces, and one is used with WPF.

The System.Drawing.Point is not so surprisingly used with the classes in the System.Drawing namespaces. The System.Windows.Point is used with WPF.
