GamePad.SetVibration Not working

Any idea how I can get rumble to work on an XBox 360 controller in a Windows game? This same code below works when it was the XNA version, maybe Rumble is a feature MonoGame doesn’t support or maybe support has been added in a more recent version than what I have (i hope!).

GamePad.SetVibration(playerIndex.Value, 1f, 1f);

In my test example, playerIndex.Value was equal to the PlayerIndex.One which is the controller I’m currently using.
