IdentityServer4Net8

Description

This is a port of the well-known IdentityServer4 library to .NET 8.0. This library provides an implementation of OpenID Connect and OAuth 2.0 server for ASP.NET Core.

Previously, the library worked on .NET Core 3.1 and did not support newer versions of .NET. This project ensures compatibility with the modern .NET 8.0 ecosystem.

Features

• ✅ Full compatibility with .NET 8.0
• ✅ OpenID Connect and OAuth 2.0 support
• ✅ ASP.NET Core Identity integration
• ✅ Entity Framework Core support for data storage
• ✅ Built-in caching support
• ✅ Ready-to-use In-Memory storage providers
• ✅ Mutual TLS (mTLS) support
• ✅ Local API Authentication integration

Components

The project includes the following main components:

Core Libraries

• IdentityServer4 - Main identity server library
• IdentityServer4.Storage - Data storage abstractions
• IdentityServer4.AspNetIdentity - ASP.NET Core Identity integration
• IdentityServer4.EntityFramework - Entity Framework provider
• IdentityServer4.EntityFramework.Storage - EF Core data models

Key Capabilities

• Client and resource management
• User authentication and authorization
• Token issuance and validation
• Support for various grant types
• Token introspection
• Token revocation
• Device Flow for devices with limited interface

Requirements

• .NET 8.0 or higher
• ASP.NET Core 8.0
• Compatible database (when using Entity Framework)

Quick Start

1. Installation

# Clone repository
git clone https://github.com/artistotless/IdentityServer4Net8.git
cd IdentityServer4Net8

2. Build Project

dotnet build

3. Configuration

Add IdentityServer to your ASP.NET Core project:

public void ConfigureServices(IServiceCollection services)
{
    services.AddIdentityServer()
        .AddInMemoryClients(Config.Clients)
        .AddInMemoryApiScopes(Config.ApiScopes)
        .AddInMemoryIdentityResources(Config.IdentityResources)
        .AddDeveloperSigningCredential();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseIdentityServer();
}

Migration from .NET Core 3.1

When migrating from the original IdentityServer4 version on .NET Core 3.1:

1. Update target framework to .NET 8.0
2. Update ASP.NET Core dependencies to version 8.0
3. Check configuration - most settings remain unchanged
4. Test all endpoints and functionality
