New command for SetRange?

Hello, I just got my Netduino plus 2 and the Getting started with Netduino book.  I am a beginner and have been reading the forums a bit and have seen that old code from the Netduino plus sometimes won't work on the plus 2.  I am in need of some help updating the potentiometer example used in the book which can be seen below:

        public static void Main()        {            // write your code here            OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);            AnalogInput pot = new AnalogInput(Pins.GPIO_PIN_A0);            pot.SetRange(100, 250);            int potValue = 0;            while (true)            {                //read the value of the pot                potValue = pot.Read();                //blink the led based on the pot's value                led.Write(true);                Thread.Sleep(potValue);                led.Write(false);                Thread.Sleep(potValue);            }        }

The problems I am having are with AnalogInput which I fixed below, the [font="'courier new', courier, monospace;"]SetRange()[/font] command, and the pots value is different from the 0 to 1023 range used in the book.  I did some debugging and with [font="'courier new', courier, monospace;"]pot.Read()[/font] it gives me values from 0 to 1, and with [font="'courier new', courier, monospace;"]pot.ReadRaw()[/font] it gives me a range of 0 to 4095.  I fixed the AnalogInput from looking at other posts on the forum, and fixed reading the pots value with [font="'courier new', courier, monospace;"]pot.ReadRaw()[/font] but can't find an equivalent command for [font="'courier new', courier, monospace;"]SetRange. [font="arial, helvetica, sans-serif;"] Here is my code:[/font][/font]

        public static void Main()        {            // write your code here            OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);            AnalogInput pot = new AnalogInput(AnalogChannels.ANALOG_PIN_A0);            int potValue = 0;            while (true)            {                potValue = pot.ReadRaw();                //read the value of the potentiometer                //blink the led based on the potentiometer's value                led.Write(true);                Thread.Sleep(potValue);                led.Write(false);                Thread.Sleep(potValue);            }        }

I got the led to blink based on the pot and now just need to set the range between 100ms delay and 250ms delay.  Any help would be great.

Thanks!

Awesome, thanks for the help!  I got it all working now using the new firmware.  Here's the code that I used in case someone else has the same problem:

using System.Net;using System.Net.Sockets;using System.Threading;using Microsoft.SPOT;using Microsoft.SPOT.Hardware;using SecretLabs.NETMF.Hardware;using SecretLabs.NETMF.Hardware.Netduino;//Make sure to add the 4.2.2 assemblies to your references if you're not on the 4.2.2 sdk.namespace Light_Pot{    public class Program    {        public static void Main()        {            // write your code here            OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);            SecretLabs.NETMF.Hardware.AnalogInput pot = new SecretLabs.NETMF.Hardware.AnalogInput(Pins.GPIO_PIN_A0);            pot.SetRange(100, 250);            int potValue = 0;            while (true)            {                potValue = pot.Read();                //read the value of the potentiometer                //blink the led based on the potentiometer's value                led.Write(true);                Thread.Sleep(potValue);                led.Write(false);                Thread.Sleep(potValue);            }        }    }}

I have a NetDuino plus 2, which I just updated to the 4.2.2.0 firmware.  I tried to run the code above and got the following error message:

How do I "grab an assembly?"   Sorry for the noob questions.
