Hi Paulo,
When Netduino first boots, all of its pins are in "input, pullup" state. This will provide a weak current (at 3.3V) which may cause your LEDs to light up very weakly. When you create an OutputPort as set it to True, that will drive current.
If you are setting the OutputPort to False and still have voltage on the pin, that shouldn't happen. If that's the case, please create a simple project (4-5 lines of code) and post the full code sample here so we can help take a look.

Chiris all digital pins has about 3.23 Voltage.
I tryed sent the fallow code to board:
OutputPort motor = new OutputPort(Pins.GPIO_PIN_D1, false);
motor.Write(true);
Thread.Sleep(10000);
motor.Write(false);
motor.Dispose();
but aways all pins show me 2.23v in low and when motor is on voltage go to 3.3v and led lights strong.
when motor is of voltage from pin 1 go to 2.3V.
Looks lime only tension change....not voltage....
