What is this?
ASP.NET Framework runs only on Windows and IIS, tied to .NET Framework. ASP.NET Core runs on Windows, Linux, and macOS with Kestrel or IIS, on modern .NET.
Why should you care?
Job postings and new products use Core. Framework is maintenance mode — fine for legacy apps, not for learning greenfield MVC in 2026.
See it live — copy this example
Create an MVC project (dotnet new mvc), add the code, and run dotnet run.
// Framework MVC 5 — Startup in Global.asax / RouteConfig
// ASP.NET Core MVC — Program.cs
builder.Services.AddControllersWithViews();
app.UseStaticFiles();
app.MapDefaultControllerRoute();
Run Example »
This lesson uses terminal or setup steps. Run commands on your computer — the live editor appears on coding lessons.
What happened?
- Core has built-in DI, unified configuration (appsettings.json), and better performance.
- Framework apps often use packages that Core replaces with first-class features.
Try it yourself
- List three differences: OS support, startup file, web server.
- Deploy a Core app with dotnet publish — output runs with dotnet ShopNest.dll.
- Read Microsoft docs "Choose between .NET and .NET Framework" for your scenario.
- Change text or labels in the example and run again — watch the browser update.
- Break the code on purpose (remove a semicolon), read the error message, then fix it.
Remember
Framework = Windows + legacy .NET. Core = modern, cross-platform, faster. Learn and build on ASP.NET Core MVC.
