How to send batch notifications in GCM using PushSharp

Question

As the title says, I have a list of all my registration IDs, and I want to send the same message to all of them at once.

I was told that GCM can handle approximately 1000 notifications at once, but I'm really confused as to how to do this in PushSharp (other than actually sending them individually, using a for loop). If anyone is familiar with this I would really appreciate some assistance.

He's some generic code

push.RegisterGcmService(new GcmPushChannelSettings(ApiKey));

push.QueueNotification(new GcmNotification().ForDeviceRegistrationId(RegistrationID)
                                  .WithJson(json));

Instead of having 1 registration ID i'd like to send in a list of them. References to FAQ's but no actual answer on how to do so.

I've never used Push Sharp, but based on this code :

You are currently using this method, which accepts a single Registration ID :

public static GcmNotification ForDeviceRegistrationId(this GcmNotification n, string deviceRegistrationId)
{
    n.RegistrationIds.Add(deviceRegistrationId);
    return n;
}

Use this method instead, which accepts multiple Registration IDs :

public static GcmNotification ForDeviceRegistrationId(this GcmNotification n, IEnumerable<string> deviceRegistrationIds)
{
    n.RegistrationIds.AddRange(deviceRegistrationIds);
    return n;
}

You need to use that using to get extended methods

using PushSharp;
using PushSharp.Android;
using PushSharp.Core;

Then you can use

GcmNotification notification = new GcmNotification().ForDeviceRegistrationId(pRegistrationIds)
                                              .WithJson(pMessage);
