Developers often see .NET Framework, .NET Core, and Modern .NET (.NET 5/6/7/8) as three different worlds.
But deep inside, all three follow the exact same architectural philosophy and execute code through the same core stages.
The outer packaging changed.
The OS support changed.
Performance improved dramatically.
But the internal engine — the idea of how .NET runs code — is consistent across all of them.
Let’s open that engine and walk through every component, slowly and clearly, like a guided museum tour.
