Is it possible to use OneSignal to create a native PushNotification to an iOS device from an asp.Net server? What's the difference between OneSignal and PushSharp? Is the difference that I would have to setup OneSignal on my mobile app instead of just allowing the app to hit endpoints on my server to register/unregister for pushNotifications(Which I was planning to use PushSharp for)
The webapp is currently being hosted on Azure, so the notification hub is an option too. But would the communication hub make me be tied down to azure?(Say I wanted to host my webapp on a different service and maybe change the server code to node)
On mobileApp startup, I'd like to send a request to the server to register the device token. It'd be best if I didn't have to config the app.
edit: I also contacted OneSignal with questions, I'll report back with any findings.
