Aeon Registry API .NET 10 Minimal API Course with C#

Welcome to the Aeon Registry, the official reference project for the Minimal API Course by Coder Foundry. This repository contains the completed codebase used throughout the course and serves as a guide for students learning how to build production-ready APIs using .NET 10, Entity Framework Core, ASP.NET Core Identity, and modern API design techniques.

Course Access

Live Demo Application

A fully deployed example of the Aeon Registry API is available for public viewing:

Live Demo (Railway Deployment): https://aeonregistryapi-production.up.railway.app/index.html

Features included in the live demo:

• Public map viewer

• Seeded sites and artifacts

• Public artifact/media endpoints

• Static UI hosted from wwwroot

• Deployed with Railway’s container-based hosting

Development Environment Used in the Course

All coding in the course videos is demonstrated using Visual Studio 2026.

Visual Studio 2026 is used for:

• Project creation

• EF Core migrations

• Debugging

• Identity configuration

• Minimal API scaffolding

• Swagger/OpenAPI customization

• Deployment walkthroughs

You may still use VS Code or JetBrains Rider …but Visual Studio 2026 will match the course experience exactly.

About This Project

The Aeon Registry is a full-featured Minimal API backend built throughout the course. It demonstrates:

• Minimal API architecture and route grouping

• Clean separation of public, private, and admin endpoints

• DTO modeling and projection

• Entity Framework Core with PostgreSQL

• Identity API endpoints

• Custom middleware (BlockIdentityEndpoints)

• Custom exception filter

• Image upload and binary image retrieval

• Data seeding from JSON + image assets

• Swagger customization with HTML-based descriptions

• Public-facing site map viewer using Leaflet.js

Technologies and Features

• Visual Studio 2026

• .NET 10 Minimal APIs

• Entity Framework Core (Npgsql)

• ASP.NET Core Identity

• Swagger / Swashbuckle

• PostgreSQL

• Custom Middleware

• Minimal API Validation

• Leaflet.js & Bootstrap 5

• Railway Deployment

Running the Project Locally

1. Install Prerequisites

• Visual Studio 2026

• .NET 10 SDK

• PostgreSQL

2. Configure Database

• Set your PostgreSQL connection string in one of the following:

• appsettings.json

• User Secrets

• Railway environment variable DATABASE_URL

3. Run the Application

• Start the solution in Visual Studio. On first run, the application will:

• Apply EF Core migrations

• Seed database content (sites, artifacts, records, media, users)

• Host Swagger

• Serve static frontend files

Local Access URLs

Swagger (API Documentation):

• localhost:port/swagger

Public Map Viewer:

• localhost:port/site/sites-map.html

Course Companion Documents

Throughout the course, you’ll work with:

• Step-by-step endpoint build guides

• Student challenges

• Full solution documents

• DTO modeling walkthroughs

• Validation + exception handling modules

• Identity customization guides

-Deployment documentation

This repository contains the final completed version used in all instructional videos.
