After years of waiting, planning, and deep engine work — the moment is here: generics are officially supported in .NET nanoFramework, and the public preview is live!

This is a huge milestone for the platform — one of the most requested features since the beginning — and it fundamentally expands the kind of C# code you can write and reuse on constrained devices. We’ve aligned with the CLI/ECMA spec, extended our metadata model, updated the type system, upgraded the toolchain, and reimagined parts of the runtime to make this real.

If you’ve ever wondered what goes into bringing a core .NET language feature from desktop CLR into an embedded runtime — from TypeSpec/MethodSpec support to generic context propagation, stackalloc, and beyond — we’re sharing a deep technical walkthrough that explains it all. It’s dense, it’s fun (for us, anyway 😄), and it’s a real look under the hood at how .NET nanoFramework continues to evolve.

Massive thanks to everyone who contributed, tested, broke things and helped fix them. Join the generics public preview via the Discord channel or GitHub Discussions, and let us know how it goes!

A new era of code reuse and expressiveness on microcontrollers starts now!
