Sample Code:

//==========C# Only

//========SET WINDOWS CURSOR========================================

        IntPtr cursor = LoadCursorFromFile("example.cur");
        bool ret_val = SetSystemCursor(cursor, OCR_NORMAL);

//========SET WINDOWS CURSOR========================================

        ColoredCursor = new Cursor(cursor);
        this.Cursor = ColoredCursor;

//========SET FORM CURSOR========================================

        if (button != null)
        {
        width = button.Size.Width;
        height = button.Size.Height;

        }

//========SET FORM CURSOR FROM IMAGE========================================

        Bitmap hh = (Bitmap)System.Drawing.Bitmap.FromFile("example.png");
        IntPtr ptr = hh.GetHicon();
        Cursor c = new Cursor(ptr);
        this.Cursor = c;

//========SET FORM CURSOR FROM IMAGE========================================

        if ((width > 0) && (height > 0))
        {
        point = new Point();
        x = (width / 2);

//========CONVERT System.Windows.Forms.Cursor TO System.Windows.Input.Cursor FOR WPF ========

        using System.Drawing;

        coordinatesFound = ClientToScreen(handle, ref point);

        if (coordinatesFound == true)
        {
          point.X += x;
          point.Y += y;
          System.Windows.Forms.Cursor.Position = point;
        }
        public static Cursor CursorFromImage()  // this returns a System.Windows.Input.Cursor
        {
            Bitmap image = (Bitmap)Bitmap.FromFile(@"c:\cursorImage.bmp");

            SafeFileHandle handle = new SafeFileHandle(c.Handle, false);
            return yourCursor = System.Windows.Interop.CursorInteropHelper.Create(handle);
        }
    }

//===========================================================================================

Alternative Managed API:

System.Windows.Forms.Cursor.Position

//========USE AN IMAGE AS A RESOURCE IN WPF FROM AN "IMAGES" FOLDER (casts a PNG file to a Bitmap) =========================

        using System.Drawing;
        using Microsoft.Win32.SafeHandles;
        using System.Windows.Resources;

        public static Cursor CursorFromImage()  // this returns a System.Windows.Input.Cursor
        {
            StreamResourceInfo sri = Application.GetResourceStream(new Uri("pack://application:,,,/Images/cursorImage.png"));
            Bitmap image = (Bitmap)Bitmap.FromStream(sri.Stream);
            IntPtr ptr = image.GetHicon();
            System.Windows.Forms.Cursor c = new System.Windows.Forms.Cursor(ptr);
            SafeFileHandle handle = new SafeFileHandle(c.Handle, false);
            return yourCursor = System.Windows.Interop.CursorInteropHelper.Create(handle);
        }

//=============================================================================================================================

Apply a custom cursor using the WPF examples like this:

this.Cursor = CursorFromImage(); // whole page

txtMyTextBox.Cursor = CursorFromImage(); // individual controls on mouse over

Alternative Managed API:

System.Windows.Forms.Cursor.Current
