Nethereum EthECKey no funciona. Los scripts no están compilados.

Si agrego esta línea a mi código, se niega a compilar. (Esto sucede con todos los scripts en Unity, incluso los vacíos)

string publicKey = Nethereum.Signer.EthECKey.GetPublicAddress(privatekey);

Código:

    string privatekey = CreateAccount();
    string publicKey = Nethereum.Signer.EthECKey.GetPublicAddress(privatekey);
    Debug.Log("\nPrivate: " + privatekey + "\nPublicKey: " + publicKey);
}


public byte[] CalculateHash(byte[] value)
{
    var digest = new KeccakDigest(256);
    var output = new byte[digest.GetDigestSize()];
    digest.BlockUpdate(value, 0, value.Length);
    digest.DoFinal(output, 0);
    return output;
}
public async Task<string> GetBalance(string chain1, string network1, string address1)
{
    string balance = await EVM.BalanceOf(chain1, network1, address1);
    return balance;
}
public static string CreateAccount()
{
    System.Random random = new System.Random();
    var bytes = new Byte[32];
    random.NextBytes(bytes);

    var hexArray = Array.ConvertAll(bytes, x => x.ToString("X2"));
    var hexStr = String.Concat(hexArray);
    return Convert.ToString(hexStr.ToLower());
}

}

¡Ayuda por favor!
