Send Message to All Users at once

[masoudamidi]

Hello,
First of all thank you for your best library.
I wanted to send push notification to all users at once. But SendNotification method just gets 1 Subscription at a time. can you develope it to get list of Subscriptions ?

This is likely something that can be done in your calling code like so (needs to be adapted to this library):

public async Task MyOuterMethod()
{
    // let's say there is a list of 1000+ URLs
    var urls = { "http://google.com", "http://yahoo.com", ... };

    // now let's send HTTP requests to each of these URLs in parallel
    var allTasks = new List<Task>();
    var throttler = new SemaphoreSlim(initialCount: 20);
    foreach (var url in urls)
    {
        // do an async wait until we can schedule again
        await throttler.WaitAsync();

        // using Task.Run(...) to run the lambda in its own parallel
        // flow on the threadpool
        allTasks.Add(
            Task.Run(async () =>
            {
                try
                {
                    var client = new HttpClient();
                    var html = await client.GetStringAsync(url);
                }
                finally
                {
                    throttler.Release();
                }
            }));
    }

    // won't get here until all urls have been put into tasks
    await Task.WhenAll(allTasks);

    // won't get here until all tasks have completed in some way
    // (either success or exception)
}
