Implementing Exponential Backoff in RestSharp for Execute<T> Method

KRestClient.cs

    public class KRestClient : RestClient
    {
        public Int32 RequestRetryCount = 5; // Attempt Types
        public Int32 BackoffRate = 100; // Milliseconds

        public KRestClient(string baseUrl) : base(baseUrl)
        {
        }

        public override IRestResponse<T> Execute<T>(IRestRequest request)
        {
            IRestResponse<T> rs;
            int count = 0;
            rs = base.Execute<T>(request);

            if ((int)rs.StatusCode == 429)
            {
                while (count <= RequestRetryCount  && (int)rs.StatusCode == 429 )
                {
                    count++;
                    Debug.WriteLine("Attempting Request. Count: " + count);
                    Thread.Sleep((count ^ 2)* BackoffRate ); // Exponential Backoff
                    rs = base.Execute<T>(request);
                }
            }
            return rs;
        }
    }
