FirebaseAuthentication.net is a powerful library that integrates Firebase Authentication into .NET applications. This guide will walk you through the installation and usage of this library in a user-friendly manner, ensuring you can effectively implement authentication flows in your applications.

Installation Steps

To get started with FirebaseAuthentication.net, you need to install the library. You can do this either through Visual Studio’s NuGet package manager or from the command line. Here’s how:

• For the base package, run the following command:

dotnet add package FirebaseAuthentication.net

• For platform-specific packages, use these commands as well:

dotnet add package FirebaseAuthentication.WPF
dotnet add package FirebaseAuthentication.UWP
dotnet add package FirebaseAuthentication.WinUI3
dotnet add package FirebaseAuthentication.Maui

• You can specify a preview version using the –version option.
• For daily preview builds, add the following Package Source to your Visual Studio: Feedz.io Package Source.

Usage Guide

Once your installation is complete, it’s time to integrate FirebaseAuthentication.net into your application. Here’s a simple analogy to help you understand its usage:

Imagine you are building a house (your application) that needs security (authentication). The FirebaseAuthentication.net library serves as your security system. You need to install the system (configuration) and then set up door access for different users (sign in methods).

Basic Configuration

Start by creating your configuration, here’s how:

var config = new FirebaseAuthConfig
{
    ApiKey = "YOUR_API_KEY",
    AuthDomain = "YOUR_AUTH_DOMAIN.firebaseapp.com",
    Providers = new FirebaseAuthProvider[]
    {
        new GoogleProvider().AddScopes("email"),
        new EmailProvider()
    }
};

Creating the Firebase Auth Client

With your configuration established, you can now create a Firebase Auth Client, which is like setting up your security panel to monitor activity:

var client = new FirebaseAuthClient(config);

Sign-In Methods

Just like granting different access levels to visitors, you can use various methods to sign in users:

• Anonymous Sign-In:

  var user = await client.SignInAnonymouslyAsync();

• Email & Password Sign-In/Sign-Up:

  var userCredential = await client.CreateUserWithEmailAndPasswordAsync(email, password, "Display Name");
  var userCredential = await client.SignInWithEmailAndPasswordAsync(email, password);

• Sign-In with Provider:

  var credential = TwitterProvider.GetCredential(access_token, oauth_token_secret);
  var userCredential = await client.SignInWithCredentialAsync(credential);

Storing User Credentials

To preserve user credentials between sessions, you can use a UserRepository like a secure vault where you store all access keys:

UserRepository = new FileUserRepository("FirebaseSample");

Troubleshooting Tips

If you encounter issues during installation or usage, consider these troubleshooting steps:

• Ensure that all dependencies are properly installed.
• Check your API keys and Firebase configuration for correctness.
• Review the output logs for any specific error messages that could provide insight.
• If the problem persists, consult the official documentation for further guidance.
