01 · What you get

Everything in one archive. Nothing beyond a SQL Server database to run it.

For training companies, academies, schools and course creators who want to sell and deliver courses on their own platform, and for developers who build such platforms for clients.

The whole e-learning cycle, with a full administration panel.

50 screens · 13 public · 13 student · 24 administrator

Student

From catalogue to certificate.

Students browse, pay, learn, take quizzes and receive a certificate with a QR code and a public verification page.

Catalogue

Searchable course catalogue with category, level, rating and price filters, and paging.

Checkout

Buy by card (Stripe), bank transfer or cash; coupons and VAT; order confirmation and invoice.

Course player

Video lessons (upload, YouTube or Vimeo) that resume where you stopped; article lessons; PDF downloads; per-lesson completion and progress bars.

Quizzes

Single-choice, multiple-choice and true/false questions with timers, attempt limits, shuffling, instant feedback and explanations — graded on the server.

Certificates

Issued automatically on completion, printable to PDF, with a QR code and a public verification page.

Account

Registration with email confirmation, password reset, profile and password change, course reviews, my learning, my certificates.

Interface

Responsive Bootstrap 5 design with light and dark themes; currency picker.

04 · Technology

No ORM. No front-end build step. Plain ADO.NET and server-rendered Razor.

.NET 10 LTS C# 13 SQL Server 2019+

Architecture

Four projects, with dependencies pointing inward only. The Application layer has no reference to Microsoft.Data.SqlClient, so the data provider could be swapped without touching business logic.

EduSphere.Web

MVC controllers (28, 112 actions), Admin area, Razor views (60), middleware

Presentation

depends on ↓

EduSphere.Infrastructure

ADO.NET repositories (20) and services

Data access

depends on ↓

EduSphere.Application

Interfaces, DTOs, shared result types

Contracts

depends on ↓

EduSphere.Domain

Entities, enums and constants — no dependencies

Core

Framework

ASP.NET Core 10 MVC (LTS, supported to November 2028), C# 13

Database

SQL Server 2019+ — LocalDB, Express, Standard or Azure SQL

Data access

ADO.NET with parameterised SQL through ISqlExecutor — no ORM

Front end

Bootstrap 5.3, Bootstrap Icons, vanilla JavaScript, jQuery Validation — no build step

Authentication

Cookie authentication, BCrypt password hashing (work factor 11)

Payments

Stripe Checkout over the REST API (no Stripe SDK)

Certificates

Print-optimised HTML saved as PDF by the browser; QR codes by QRCoder

Logging

Serilog (console and file)

NuGet

12 packages, all MIT or Apache 2.0

Design decisions

Security, data integrity and ownership, built in.

Parameterised SQL Server-side pricing Soft deletes

Every query is parameterised

ISqlExecutor has no overload for interpolated strings, so SQL injection is a compile error.

Paid content is not reachable by URL

Videos and PDFs live in App_Data and are streamed by an action that checks enrolment on every request.

Money is never trusted from the browser

Orders are priced server-side on display and again on submit; card payments are confirmed with Stripe directly.

Quizzes are graded on the server

Correct answers are never sent to the browser before submission; answered questions lock.

Deletes are refused, not cascaded

A course with students or a category holding courses refuses deletion with an explanation.

Ownership is enforced in SQL

The signed-in user's id is part of every student query, so a guessed id returns no row.

05 · Deploy

Runs on IIS, Kestrel, Docker or Azure App Service.

Install time: 15–30 minutes. No Node.js, npm or front-end tooling is needed.

.NET SDK

10.0 LTS

SQL Server

2019 or later — Developer, Express, LocalDB or Azure SQL

Server size

Minimum 2 vCPU, 2 GB RAM, 20 GB disk

Hosting cost

About USD 10–25/month on a small VPS with SQL Express

06 · AI-ready

The project can be modified with Claude, Codex and Antigravity.

A CLAUDE.md file in the repository gives AI coding tools their orientation, and the codebase has no hidden layers: one route to the database and no front-end build pipeline.
