This is a really old post, but since It's not answered and I just came across same problem, what I did was the next: 

WindowManagerLayoutParams windowManagerLayoutParams = new WindowManagerLayoutParams();
windowManagerLayoutParams.CopyFrom(Window.Attributes);
windowManagerLayoutParams.ScreenBrightness = 1f; //set screen to full brightness
Window.Attributes = windowManagerLayoutParams;

To set it back to auto: 

WindowManagerLayoutParams windowManagerLayoutParams = new WindowManagerLayoutParams();
windowManagerLayoutParams.CopyFrom(Window.Attributes);
windowManagerLayoutParams.ScreenBrightness = -1;
Window.Attributes = windowManagerLayoutParams;

In case you want to save the old brightness and set it back to what it was, you can just store it in a variable and use it again.
