MFW 4.2 Beta Problem - HashAlgorithm not supported?

Hi,

I’m using the 4.2 Beta on EMX and attempting to use the HashAlgorithm class.
This is the code:

using System;
using Microsoft.SPOT;
using System.Security.Cryptography;
using System.Text;

namespace HashTest
{
    public class Program
    {
        public static void Main()
        {
            Debug.Print(
                Resources.GetString(Resources.StringResources.String1));

            HashAlgorithm ha = new HashAlgorithm(HashAlgorithmType.SHA1);
            byte[] toBeHashed = Encoding.UTF8.GetBytes("A String to Be Hashed");
            byte[] hashCode = ha.ComputeHash(toBeHashed);
            Debug.Print(hashCode.ToString());
        }

    }
}

This works on the Emulator, but not EMX (UN_SUPORTED Exception).
Any ideas?

Thanks,
John

We gave not added or devided on any of the crypto libs. Next release is days away.
