Duende IdentityServer with ASP.NET Core Identity and MongoDB as Database [Detailed Guide]

This tutorial shows you how to set up Duende IdentityServer with ASP.NET Core Identity from scratch, using MongoDB as the underlying database. We'll configure ASP.NET Core Identity to store client credentials in MongoDB. When a client requests authentication from IdentityServer, those credentials are validated directly against the MongoDB database through ASP.NET Core Identity.

By the end of this guide, you'll have a fully secured Web API protected by Duende IdentityServer — built entirely from the ground up.

The source codes are given in GitHub repository.
