History and Evolution of .NET
Lesson 2: History and Evolution of .NET
In this lesson, you will learn how .NET has evolved over time, from its early beginnings to the modern unified platform we have today.
📜 The Beginning
Microsoft started working on .NET in the late 1990s to modernize software development for Windows. The first official release was:
- .NET Framework 1.0 in 2002
This version included the Common Language Runtime (CLR) and Base Class Library (BCL).
🔄 .NET Framework Growth
Over the years, .NET Framework received many updates and improvements:
- ASP.NET: For building web applications.
- Windows Forms: For building desktop apps.
- WPF: Rich desktop applications with modern UI.
- WCF: Services and communication.
- Entity Framework: Object-relational mapping (ORM).
🌐 The Cross-Platform Revolution
With the rise of Linux, macOS, and open-source development, Microsoft introduced:
- .NET Core 1.0 in 2016: Lightweight, modular, and cross-platform.
- .NET Core 2.0: More APIs and compatibility with existing .NET libraries.
- .NET Core 3.0: Added support for Windows Desktop (WPF and Windows Forms).
🔗 The Unification: .NET 5 and Beyond
In 2020, Microsoft launched .NET 5, a major milestone that combined:
- .NET Core
- Xamarin (for mobile development)
- Mono (for lightweight environments)
This unification made it easier to build any kind of app with one platform.
- .NET 6 (2021): Long-Term Support (LTS) release with performance improvements.
- .NET 7 (2022): Continued improvements and new features.
- .NET 8 (2023): Focus on cloud-native and AI workloads.
