Dynamic Push Notifications

Hi guys,

I've created a SignalR Server in ASP.NET for my Xamarin.Forms application to handle realtimed actions.

What would be the best way to submit Push Notifications through my ASP.NET SignalR server to specific devices?

My app handles emergencies. When someone sends an emergency through my application, the server broadcasts an emergency to each device in radius of 500 metres. This works so far fine, now I'd like to submit also a push notification to each device in radius of 500 metres.

Is there any library for push notifications, that allows me to send push notifications to specific devices registered for this app?

Thanks a lot!
