Hi,

Receive push ok,
Iam need help
Send message problems, see:

FirebaseApp.Create(new AppOptions()
{ Credential = GoogleCredential.FromJson(jsonContent) });

{
var registrationToken = "cB0E5BH-RyO..blabla";

var message = new Message()
{
Data = new Dictionary()
{
{ "score", "850" },
{ "time", "2:45" },
},
Token = registrationToken,
};

try
{
string response = await FirebaseMessaging.DefaultInstance.SendAsync(message);
Console.WriteLine("Successfully sent message: " + response);
}
catch (Exception ex)
{
Console.WriteLine("SendAsync-error: \n" + ex.ToString() + "\n\n");
}
}
