It is not possible using the .NET BCL. However if you really want it you can 
use native SetCursorPos inUser32.dll.
[DllImport("User32.dll")]
private static extern bool SetCursorPos(int x, int y);
As others will most likely point out, you can achieve the same using 
System.Windows.Forms, however when developing a WPF application 
prefer use DllImport.
