If you don t want to reference Forms you can use interop to get the cursor position  using System Runtime InteropServices  using System Windows     Or use whatever point class you like for the implicit cast operator       lt summary gt      Struct representing a point       lt  summary gt   StructLayout LayoutKind Sequential   public struct POINT       public int X      public int Y       public static implicit operator Point POINT point                return new Point point X  point Y                 lt summary gt      Retrieves the cursor s position  in screen coordinates       lt  summary gt       lt see gt See MSDN documentation for further information  lt  see gt   DllImport  quot user32 dll quot    public static extern bool GetCursorPos out POINT lpPoint    public static Point GetCursorPosition         POINT lpPoint      GetCursorPos out lpPoint          NOTE  If you need error handling        bool success   GetCursorPos out lpPoint          if   success               return lpPoint
