Did you resolved?

you must use :

using System.Runtime.InteropServices;

and declare :

C#

[DllImport("user32.dll")]
static extern IntPtr SetCapture(long hWnd);

[DllImport("user32.dll")]
static extern long ReleaseCapture();

inside class declaration, where you will use or use like

GenericClass.SetCapture(Control.Handle)

if used as shared function (must be public ofcourse) and use like you write above.

Regards!
