ESC - Code Problem

Hello, i am having problems with controlling my ESC. I dont even hear the beep!!!!!

here is the code

namespace lets_start
{
    public class Program
    {
        public static void Main()
        {           
             
            while (true)
            {
                motorOnThenOff();
              //  motorTest();
                
            }  
        }

        static void motorOnThenOff()
        {
            OutputPort motor = new OutputPort(Pins.GPIO_PIN_D5, false);

            int onTime = 2500;  //the number of milliseconds for the motor to turn on for
            int offTime = 1000; //the number of milliseconds for the motor to turn off for

            motor.Write(true);       // turns the motor On
            Thread.Sleep(onTime);    // waits for onTime milliseconds
          //  motor.Write(false);      // turns the motor Off
          //  Thread.Sleep(offTime);   // waits for offTime milliseconds

            motor.Dispose();
        }

        static void motorTest()
        {
        
            PWM Motor = new PWM(Pins.GPIO_PIN_D5);
            
            while (true)
                
                Motor.SetDutyCycle(100);
                Thread.Sleep(500);
                Motor.SetDutyCycle(50);
                
                //Thread.Sleep(800);
                //Motor.SetDutyCycle(0);
            } 
            
          

        }

    }

Thanks!! Well i have seen that code but i still got problems :/ using an arduino of a friend of me i hear the beeps!! but using the netduino nothing. Of course am a beginer!!

Hey the other tread is from me in my case you had first to set the throttle of the esc to 100% and then connect the esc and motor (esc and motor should not get any power input before), then set throttle to 0%. After that your esc should sound correct and you can control your motor then set throtte to 20% to begin ^^

Don't know which motor you have, but start only with 20%, else this can happen:

Oh dear! That did hurt I suppose?

Oh dear! That did hurt I suppose?

Thanks guys for ur help i will try it out i will let you now about my progress!!!!

Well i am always be carefull with this things coz am using a jet motor!!!! (i saw similar motor working)

           **** SpeedController xl5 = new SpeedController(Pins.GPIO_PIN_D5, new TRAXXAS_XL5());

Well my ESC in not a TRAXXAS one. I have seen similar code and i thing so that need a another one class in order to instansiate
SpeedController() .

Yeah I know, I also have no Traxxas one but works I really didn't understand the whole code yet, so I used this at the moment.

What is the pin configuration? I assume the D5 pin is the pin to the ESC. But where do D0 and D1 get connected to?
