Я решаю проблему следующим образом;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://android.clients.google.com/c2dm/send");
request.Method = "POST";
request.KeepAlive = false;
NameValueCollection postFieldNameValue = new NameValueCollection();
postFieldNameValue.Add("registration_id", registrationId);
postFieldNameValue.Add("collapse_key", "1");
postFieldNameValue.Add("delay_while_idle", "0");
postFieldNameValue.Add("data.message", message);
string postData = GetPostStringFrom(postFieldNameValue);
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
request.ContentLength = byteArray.Length;
request.Headers.Add(HttpRequestHeader.Authorization, "GoogleLogin auth=" + authTokenString);
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

sender,
System.Security.Cryptography.X509Certificates.X509Certificate
pCertificate,
System.Security.Cryptography.X509Certificates.X509Chain pChain,

{
return true;
};

WebResponse response = request.GetResponse();
HttpStatusCode responseCode = ((HttpWebResponse)response).StatusCode;
if (responseCode.Equals(HttpStatusCode.Unauthorized) || responseCode.Equals(HttpStatusCode.Forbidden))
{
Console.WriteLine("Unauthorized - need new token");
}
else if (!responseCode.Equals(HttpStatusCode.OK))
{
Console.WriteLine("Response from web service not OK :");
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
}
StreamReader reader = new StreamReader(response.GetResponseStream());
string responseLine = reader.ReadLine();
reader.Close();
