Answer 1

I believe that is related to:
Add iPhone push notification using ASP.NET server
Read through the linked project in there. It is pretty comprehensive. You can actually just use that library... it is pretty good.
Unless I misunderstood the question?

Use following snippet to send Push Notification
public void PendingNotification(string DeviceToken,string message)
{
try
{
int port = 2195;
//Developer
String hostname = "gateway.sandbox.push.apple.com";
//Production
//String hostname = "gateway.push.apple.com";
String certificatePassword = "XXXXXXX";
string certificatePath = Server.MapPath("~/cer.p12");
TcpClient client = new TcpClient(hostname, port);
X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), certificatePassword);
X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Tls, false);
//String DeviceToken = "XXXXXXXXXXXX";
String LoginName = "Name";
int Counter = 1; //Badge Count;
String Message = message;
String UID = "your choice UID";
string payload = "{\"aps\":{\"alert\":\"" + Message + "\",\"badge\":" + Counter + ",\"sound\":\"default\"},\"UID\":\"" + UID + "\",\"LoginName\":\"" + LoginName + "\"}";
MemoryStream memoryStream = new MemoryStream();
BinaryWriter writer = new BinaryWriter(memoryStream);
writer.Write((byte)0);
writer.Write((byte)0);
writer.Write((byte)32);
writer.Write(HexStringToByteArray(DeviceToken.ToUpper()));
writer.Write((byte)0);
writer.Write((byte)payload.Length);
byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
writer.Write(b1);
writer.Flush();
byte[] array = memoryStream.ToArray();
sslStream.Write(array);
}
catch (Exception ex)
{
//Response.Write(ex.Message);
}
}
public static byte[] HexStringToByteArray(string hex)
{
return Enumerable.Range(0, hex.Length)
.Where(x => x % 2 == 0)
.Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
.ToArray();
}
public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
return true;
Console.WriteLine("Certificate error: {0}", sslPolicyErrors);
return false;
}
