This Home repository is the starting point for developers that want to learn about nanoFramework, contribute to it or opening issues. It contains links to the various GitHub repositories used by nanoFramework.
nanoFramework goal is to be a platform that enables the writing of managed code applications for constrained embedded devices. Developers can harness the familiar IDE Visual Studio and their .NET (C#) knowledge to quickly write applications without having to worry about the low level hardware intricacies of a micro-controller.
Being a developer you'll probably will fit in one (or maybe both 😉) of the following profiles:
- Developer: if your goal is to develop C# applications for micro-controllers.
- Contributor: if you are interested in actively contributing by coding (native, managed, C, C++, CMake), writing documentation or participating in the overall project organization.
Each of the following ZIP files contains the image files for nanoBooter and nanoCLR in various formats (HEX, BIN and DFU). They should be flashed in the target boards using an appropriate software utility.
The stable versions are RTM builds with the smallest possible size. They include the latest stable version. The debugging feature is disabled and only minimal (or none) error messages.
The preview versions are continuous builds of the reference targets. They include the latest version of all features and bug corrections. They also have the debugging feature enabled along with detailed error messages.

Some of the best ways to contribute are to try things out, file bugs, and join in design conversations. If you are having issues or need a clarification about something, instead of opening an issue the best way is to start a conversation in one of our Slack channels. Please select the one that's most appropriate to the matter you are facing.
If you've find a bug or can't use Slack, please open an issue at Issues. We ask you to open an issue only when you have a real and confirmed one. Don't open an issue for support requests or to start a discussion. For that you'll get a better (and quicker!) support/feedback in one of the Slack channels. You can request an invitation for the Slack workspace in this form.
Looking for something to work on? Check the list of up-for-grabs issues on the Home repo, that's a great place to start.

The project documentation is a great place to find information about nanoFramework, no matter if you are newcomer or a veteran. It's organized in the following categories:
- API reference documentation for the various class libraries.
- Developing C# applications using nanoFramework.
- Building an image to load on a target board.
- nanoFramework architecture and how the different pieces fit together.
- Contributing to nanoFramework includes an overview on how you can contribute to the project.
There is a blog where we try to post detailed updates about the development status, technical posts about a particular feature ou a design option.
There are a number of people behind this project. We are mostly embedded systems enthusiasts, passionate about coding and people that like challenges. All of us have our daily jobs and we work on this project in our free time. That is to say that you can always expect an answer from us. Maybe not instantly but in a - hopefully - timely fashion 😉 !
This project has adopted the code of conduct defined by the Contributor Covenant to clarify expected behavior in our community.
