FireForNet.Firebase.AppCheck

Firebase App Check for the FireForNet Firebase Client SDK for .NET.

About FireForNet

FireForNet is a platform-agnostic, .NET-native Firebase Client SDK developed as part of the Circuids ecosystem. It provides a consistent Firebase client development experience across .NET application environments, while allowing platform-specific implementations where Firebase requires them.

About This Package

This package provides the Firebase App Check implementation for FireForNet:

App Check token exchange
Token caching and auto-refresh
Token-change callbacks
HTTP App Check header propagation through the shared FireForNet interceptor pipeline

Installation

dotnet add package FireForNet.Firebase.AppCheck

Targets net10.0. References FireForNet.Firebase.Core transitively.

Setup

builder.Services.AddFirebaseAppCheck(options =>
{
    options.TokenAutoRefreshEnabled = true;
});

Use debug provider tokens only for local development.

Usage

Resolve IFirebaseAppCheck from DI:

public class AttestationService(IFirebaseAppCheck appCheck)
{
    public async Task<string> GetTokenAsync()
    {
        var result = await appCheck.GetTokenAsync();
        return result.Token;
    }

    public async Task<string> GetLimitedUseTokenAsync()
    {
        var result = await appCheck.GetLimitedUseTokenAsync();
        return result.Token;
    }
}

AppCheckTokenResult exposes Token, ExpiresAt, and IssuedAt. Token changes can be observed with OnTokenChanged, which returns an IAsyncDisposable that unregisters the callback when disposed.

Documentation

Comprehensive FireForNet documentation is being prepared for the Release Candidate stage.

Project Status

FireForNet is currently available as a Preview release and is approaching its Release Candidate milestone. APIs, package structure, and implementation details may continue to evolve before RC and GA.

The RC milestone will be followed by an extensive cross-platform validation and testing phase before the first GA release.

All FireForNet packages are part of a coordinated release train and share the same version number.

Source Availability

FireForNet is currently being developed in a private source repository during the Preview development phase. The source will be made publicly available as the project approaches its open-source phase, with the public repository established from the appropriate release milestone.

Until then, NuGet Preview packages provide the public distribution channel for evaluating and using FireForNet.
