## Overview

This repository contains two ASP.NET Core MVC teaching applications. The main app’s core workflow is an HTTP request routed to a controller, which validates/maps product or visitor input, reads or writes through EF Core, and returns a view or redirect; filters add cross-cutting behavior. The second app isolates IP-whitelist middleware. The README documents additional category, cookie, AJAX, configuration, session, and Razor capabilities, but their detailed wiring is not established by the sampled source. Dashed links mark those documentation-level or unverified integrations.

Main entry points: [`MyAspNetCoreApp.Web/Program.cs`](https://github.com/fcakiroglu16/aspnetcore-mvc-course/blob/master/MyAspNetCoreApp.Web/Program.cs) (MVC request pipeline), [`MyAspNetCoreApp.Web/Models/AppDbContext.cs`](https://github.com/fcakiroglu16/aspnetcore-mvc-course/blob/master/MyAspNetCoreApp.Web/Models/AppDbContext.cs) (EF context), [`MyAspNetCoreApp.Web/Controllers/ProductsController.cs`](https://github.com/fcakiroglu16/aspnetcore-mvc-course/blob/master/MyAspNetCoreApp.Web/Controllers/ProductsController.cs) (Product actions), [`MyAspNetCoreApp.Web/Controllers/HomeController.cs`](https://github.com/fcakiroglu16/aspnetcore-mvc-course/blob/master/MyAspNetCoreApp.Web/Controllers/HomeController.cs) (Home actions)
