C# all the way down to the microcontroller.
.NET nanoFramework™ makes it easy to write C# code for embedded systems. Use the tools and skills you already have – Visual Studio, NuGet, real debugging – on constrained devices from many silicon vendors.
dotnet tool install -g nanoffusing System.Device.Gpio;
using System.Threading;
var gpio = new GpioController();
var led = gpio.OpenPin(2, PinMode.Output);
while (true)
{
led.Toggle();
Thread.Sleep(500); // that's it. blinky.

Why .NET nanoFramework
Embedded development that feels like the rest of your .NET work.
Your C# skills, unchanged
APIs aligned with .NET IoT. Generics, familiar namespaces and NuGet packages – no new language to learn.
Real debugging on real hardware
Breakpoints, stepping and watches on the device, from Visual Studio or VS Code. No printf archaeology.
Connected by default
Wi-Fi, Ethernet and AT modems, TLS 1.3, MQTT, and SDKs for Azure and AWS.
Open, community-driven
Built in the open on GitHub by contributors, partners and silicon vendors. Successor to .NET Micro Framework.
Get started
From unboxing to blinking in three steps.
Grab a supported board, a USB cable and ten minutes. The full walkthrough lives in the docs.
Read the getting-started guideInstall the extension
For Visual Studio or VS Code, from the Marketplace.
Flash the firmware
nanoff installs the right image for your board.
nanoff --target <YOUR_TARGET> --serialport COM3 --updateDeploy and debug
Create a project from the template, press F5, set a breakpoint. You're doing embedded.
Hardware
Runs on the chips you already use.
Reference targets are built, tested and published by the core team on every release. Flash one with nanoff and you're running.

Sponsor the project
.NET nanoFramework is free. Keeping it that way isn't.
The project is built by volunteers and funded entirely by sponsors. Your support pays for build and test infrastructure, hardware for the test lab, documentation and learning materials. If .NET nanoFramework is part of your product, please help keep it healthy.
Both go straight to the project. On Open Collective every contribution and expense is public. Building a product on .NET nanoFramework? Talk to us about partnering.
