Fireship’s ‘.NET in 100 Seconds’ covers the history, architecture, and ecosystem of Microsoft’s unified cross-platform runtime.

  • .NET was originally Windows-only (early 2000s), rebooted as .NET Core in 2016, then unified into modern .NET in 2020 with yearly releases.
  • Targets Linux, macOS, cloud, and Windows — a significant shift from its origins.
  • The Common Language Runtime (CLR) handles memory management, garbage collection, and security across C#, F#, and Visual Basic.
  • All supported languages compile to Common Intermediate Language (CIL), then JIT or AOT compiled to native machine code.
  • Key ecosystem components: ASP.NET (web), Blazor (WebAssembly), Entity Framework Core (ORM), MAUI (cross-platform mobile), Polly (fault tolerance).
  • Third-party embeds include Unity (games), QuantConnect (algo trading), and AutoCAD (CAD/engineering).
  • NuGet is the package manager covering virtually every use case in the ecosystem.
