Firebase Cloud Messaging only supports delivering messages to iOS, Android, and Web clients. There is no support for delivering messages to macOS apps at the moment.

In my Xamarin forms application I want to handle some functionality while bluetooth state change state. Is there any event which will fire when bluetooth is on/off. Please help me.
Xamarin Forms doesn't have the capacity built-in so you will need to use a 3rd party package or create your own native handlers for each platform and use dependency injection to access it from forms. Some good links to get you started are
https://forums.xamarin.com/discussion/15794/ble-bluetooth-low-energy-cross-platform-support
And this is an open source project with example code on interacting with Bluetooh on 2 platforms. Bluetooth and BLE are different with WP8 not supporting BLE but I believe UWP does, though thats only in preview.

I have a few questions for building apps.
Can u make apps using c++?
How do I get an app from my testing environment onto my windows phone 8?
Do I have to worry about cross phone compatibility?
paying $200 to put apps on the marketplace is extremely out of the question. I just want to test my app on my actual phone.
I assume you are trying to develop windows phone 8 apps, and yes you can develop using c++, but you have to read up on async await, as the sdk have tons of it in order to give the fluid user experience.
And the last time I checked, the developer account only costs $25 now
Well Yes!
You need to unlock your Windows Phone to actually test in on a Hardware Device.
You don't need to worry about the compatibility, but you should take note of the High-Res Phones that are in the Market too.

Can someone please help me to better understand how NFC-enabled smartphones work? Is it controlled by an app on the smartphone or by the device itself?
Thanks!
NFC stands for Near Field Communication. Apps control the NFC chip/antenna that is built in the phone. So a phone without the NFC hardware, could never have an NFC app work on it. So you do need both in order for it to work.
Basically think of NFC just like bluetooth, only that NFC has an effective range of around 4-5cm and not any further.
I think this like might help: http://www.androidauthority.com/how-it-works-nfc-near-field-communication-97144/
If there is anything else specifically that you don't understand, please say so.

I've seen a great deal of games on windows phone featuring the xbox mark and a lot not featuring it. I have some questions about that:
1) What is the difference between the 2 types of games? As i see it, i think that the xbox versions can award achievements for some tasks on the users xbox profile. Is there more?
2) How can one add a game to the marketplace and make it xbox-able?
Any tutorial or web source could be of great use!
To get Xbox live approved, I think you have to work with Microsoft - you have to get your company approved - see http://www.xbox.com/en-US/developers/wp7 for more details.
