The project

From a nanoFramework team member

.NET nanoFrameworkis an open-source platform that brings C# and .NET development to resource-constrained embedded devices — ESP32, STM32, and more. I'm a team member of the project.

CCSWE.nanoFramework covers what mainline won't take: libraries that are too opinionated, out of scope, or take a different architectural position. When work meets mainline's bar, it goes back upstream. The DhcpServer library I wrote was accepted into the nanoFramework project as a direct replacement for the official implementation — the clearest example of how this two-way relationship works.

The audience is .NET developers who want familiar patterns — Generic Host, DI, MEL logging, ASP.NET Core-style routing — on hardware that can't run the full runtime. If you've written .NET server-side code, this ecosystem will feel like home.

Library collection

Libraries across 4 areas.

Application Infrastructure

Generic Host, DI, MEL logging, and pub/sub messaging — the patterns .NET developers already know, running on a microcontroller.

  • CCSWE.nanoFramework.HostingNuGet downloads

    .NET Generic Host on embedded hardware — DeviceHostBuilder, DI container, hosted services, and startup initializers that can abort before services launch.

  • CCSWE.nanoFramework.ConfigurationNuGet downloads

    Pluggable configuration management — swappable storage backends, change events, and validation. In-memory and file-system backends included.

  • CCSWE.nanoFramework.LoggingNuGet downloads

    MEL-backed logging — ConsoleLogger, configurable log levels, standard ILogger interface.

  • CCSWE.nanoFramework.MediatorNuGet downloads

    Async pub/sub event mediator — DI-registered singleton handlers and runtime-registered transient handlers. Decouples publishers and subscribers cleanly.

Networking & Services

Production networking for embedded devices — a web server, DHCP server, and mDNS responder that hold up in real applications.

  • CCSWE.nanoFramework.WebServerNuGet downloads

    Async web server modelled after ASP.NET Core — attribute-based controllers, routing, parameter binding, custom middleware, pluggable auth, and HTTPS.

  • CCSWE.nanoFramework.DhcpServerAccepted upstreamNuGet downloads

    RFC 2131 DHCP server — full message set, lease renewal and rebinding, captive portal URL, extensible options. Accepted into the nanoFramework project as the official implementation.

  • CCSWE.nanoFramework.MdnsServerNuGet downloads

    mDNS responder with DI support — answers A, PTR, SRV, and TXT queries automatically. Integrated via AddMdnsServer().

Core & Utilities

The foundation everything else is built on — thread-safe collections, threading primitives, argument validation, and a faster Math implementation.

  • CCSWE.nanoFramework.CoreNuGet downloads

    Shared utility classes — Ensure/ThrowHelper for argument validation, StringExtensions, and reflection helpers.

  • CCSWE.nanoFramework.ThreadingNuGet downloads

    Thread management — ThreadPool, ConsumerThreadPool (queue-backed with callback), and multi-handle wait utilities.

  • CCSWE.nanoFramework.Collections.ConcurrentNuGet downloads

    Thread-safe collections — ConcurrentList (thread-safe ArrayList) and ConcurrentQueue.

  • CCSWE.nanoFramework.MathNuGet downloads

    Fast System.Math — strips NaN-handling overhead for speed on constrained hardware. Improvements contributed back to nanoFramework/System.Math.

  • CCSWE.nanoFramework.FileStorageNuGet downloads

    IFileStorage abstraction over the device file system — makes storage access testable and swappable.

  • CCSWE.nanoFramework.Threading.TestFrameworkNuGet downloads

    Test helpers for ThreadPool state management in nanoFramework unit tests.

Flagship

NeoPixel — the LED library it should have been.

The most downloaded library in the collection by a wide margin. The official nanoFramework LED library is slow and feature-limited — this is the replacement. NeoPixel uses ESP32's RMT peripheral for significantly faster output, supports a broader API, and integrates directly with the Graphics library for color conversion and animation utilities.
