✅ 1. .NET (formerly .NET Framework / now .NET 5+)

.NET is the overall software development platform from Microsoft.
It provides:

• A runtime (CLR — Common Language Runtime)
• A base class library (BCL)
• Languages like C#, VB.NET, F#
• Tools for building many types of apps:
  • Desktop (WPF, WinForms)
  • Mobile (MAUI/Xamarin)
  • Web (ASP.NET)
  • Cloud
  • Games (Unity uses C#)

Key note:

Originally there was .NET Framework (Windows-only).
Now there is .NET (Core-based) — cross-platform.
