Is an example of Xamarin.Forms Droid & iOS application that authenticates users via Firebase and consuming a protected .NET Core WEB API backend with Firebase OAuthToken.

Beside that you will also find examples of:

• IOC using Autofac
• PropertyChanged.Fody
• Input validation
• IValueConverter
• Dynamically enable/disable Command with ChangeCanExecute
• Styles

• Sign-in and navigate to console
• Create a new project
  • Add application for Android
    • Download google-services.json
  • Add application for iOs
    • Download GoogleService-Info.plist
• Open Authentication section
  • Switch to "Sign-in method" tab
    • Enable "Email/Password"
  • Switch to "Users" tab
    • Add new user

• In Startup.ConfigureServices(..) set the var firebaseProjectId to your firebase id project.

• Add "Xamarin.Firebase.Auth" NuGet package
• Import "google-services.json" and set the building action to "GoogleServicesJson"
  • In other words the .csproj should contain the next line: <GoogleServicesJson Include="google-services.json" />
• Make sure that your package name is identical to the package name inside "google-services.json"
• Add the next line of code in the MainActivity.cs OnCreate before LoadApplication:

FirebaseApp.InitializeApp(Application.Context);

• Implement IFirebaseAuthenticator

• Add "Xamarin.Firebase.iOS.Auth" NuGet package to iOS project
• Import "GoogleService-Info.plist" and set the building action to "BundleResource"
• Make sure that your bundle identifier is identical to the bundle identifier inside "GoogleService-Info.plist"
• Add the next line of code in the AppDelegate.cs FinishedLaunching before LoadApplication:

Firebase.Core.App.Configure();

• Implement IFirebaseAuthenticator
• Please note that if you want to test on the iOS simulator you will have to do one extra step as described here due to a bug.
