Expo.io Push Notifications Send Through C#

Expo_Push_Notifications_Helper.cs

public class ExpoPushHelper
{
    public static dynamic SendPushNotification(string ExpoToken)
    {
        dynamic body = new
        {
            to = ExpoToken,
            title = "hello",
            body = "world",
            sound = "default",
            data = new { some = "daaaata" }
        };
        string response = null;
        using (WebClient client = new WebClient())
        {
            client.Headers.Add("accept", "application/json");
            client.Headers.Add("accept-encoding", "gzip, deflate");
            client.Headers.Add("Content-Type", "application/json");
            response = client.UploadString("https://exp.host/--/api/v2/push/send", JsonExtensions.ToJson(body));
        }
        var json = JsonExtensions.FromJson<dynamic>(response);
        return json;
    }
}

I had an error which wasn't decoded with webclient like this because expo sent back as gzip.
I added this override of webclient and it worked to get the correct response
From here: https://stackoverflow.com/questions/2973208/automatically-decompress-gzip-response-via-webclient-downloaddata

` class MyWebClient : WebClient

{

    protected override WebRequest GetWebRequest(Uri address)

    {

        HttpWebRequest request = base.GetWebRequest(address) as HttpWebRequest;

        request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip;

        return request;

    }

}`

Also, another thing I found I had to do was add this for emojis
client.Encoding = System.Text.Encoding.UTF8;

after you create the client
