SimulateKeyPress isn't working

[TristanMann17]

    public void pressTab()
             {
                 sim.SimulateKeyPress(VirtualKeyCode.TAB);
             }

//simulate key press is giving the error "InputSimulator does not contain a definition for SimulateKeyPress", I'm not sure what it is, /i'm using WindowsInput.native and WindowsInput.

[UsefullProgrammer]

is
sim.Keyboard.KeyPress

sim.SimulateKeyPress
