Hi all,
I would like to send push notifications to all users using my asp.net application, via browser (Chrome/FireFox).

My understanding is, user need to subscribe to FCM (like registering the device to get the token), and google will push messages to those registered devices.

Base on my research there are few 3rd party API will help us to push messages with same menthod.

But i m trying to link direct to google, and allow google to push to my devices.

My first thing i m trying to is to register my devices. I have no idea & the resources are limited for .NET.

If anyone ever tried or have knowledge, feel free to share.

Thanks!

What I have tried:

Third party API (onesignal) to push messages and its working.
