Nedo.AspNet.Authentication

The core of the modular auth platform: JWT Bearer middleware, the DI engine that wires every provider together, the AuthContext that fronts HttpContext.User for clean DI, and the authorization plumbing every other package builds on.

Install

dotnet add package Nedo.AspNet.Authentication

This package is referenced transitively by every provider package — install it directly only when you want to consume the framework without a specific identity provider (e.g. you're issuing JWTs from another service and just want this app to validate them as a resource server).

Quickstart — resource-server mode (validate someone else's JWTs)

using Nedo.AspNet.Authentication;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddAuthentication("Bearer")
    .AddJwtBearer(opts =>
    {
        opts.Authority = "https://your-issuer.example.com";
        opts.Audience  = "your-api";
    });

builder.Services.AddAuthorization();
builder.Services.AddHttpContextAccessor();
builder.Services.AddScoped<IAuthContext, AuthContext>();

var app = builder.Build();
app.UseAuthentication();
app.UseNedoAuthContext();   // populates IAuthContext from HttpContext.User
app.UseAuthorization();

app.MapGet("/me", (IAuthContext auth) => new { auth.UserId, auth.Email });
app.Run();

Quickstart — issue your own JWTs

For username/password + refresh tokens, use Nedo.AspNet.Authentication.Local (which references this package and adds the issuer + EF persistence).

For social providers (Google, Microsoft, Apple, GitHub, Facebook, Keycloak), pair this with one of the Nedo.AspNet.Authentication.{Provider} packages.

What's in here

Type Purpose
AuthContext Default IAuthContext implementation reading HttpContext.User.
AuthContextMiddleware Populates IAuthContext after authentication runs. Wire with app.UseNedoAuthContext().
NedoAuthorizationPolicy Helpers for the [Authorize] policy surface.
Extension methods AddNedoAuth*, MapNedo* — surfaced by every provider package.
