What is the .NET Micro Framework?

.NET Micro Framework is an open source platform that enables you to write managed code C# applications using Visual Studio for resource constrained embedded devices. .NET Micro Framework is open sourced by Microsoft Open Technologies.

What is .NET Micro Framework used for?

.NET Micro Framework can be used to build embedded devices on resourced constrained devices running on a microcontroller with just a few hundred kilobytes of RAM and storage. Developers can use Visual Studio, C# and .NET knowledge to quickly write embedded applications without having to worry about the intricacies of each microcontroller. A developer can purchase a .NET Micro Framework compatible board, connect the board to their development computer running Visual Studio and start writing applications for physical devices. No extensive knowledge of hardware design is needed to get started writing code for physical devices.

Why .NET Micro Framework?

Great Developer Experience

Use best in-class development and debugging tools of Visual Studio to easily create micro intelligent devices.

Rapid prototyping

Bring your ideas to life in hours instead of days or weeks with the .NET Gadgeteer platform. Quickly and easily develop your inventions to show people your creative designs.

Leverage .NET and C#

Harness your existing C# and .NET knowledge base to bring cool and innovative devices to life.

  • .NET Micro Framework 4.4 is now available! October 20, 2015
    The .NET Micro Framework team is pleased to announce the release of .NET Micro Framework 4.4. We fixed several long outstanding issues as well as improved the reliability of lwIP network stack and debugging experience through Visual Studio 2015. The 4.4 version also features several types from Windows.Devices namespace in the UWP API and experimental...
  • LLILUM roadmap and latest additions October 3, 2015
    We just finished pushing several changes that enable multi-threaded applications to work on M3 and M4 Cortex processors, including FP support. We are now supporting System.Threading namespace, on par with NET MF, and also System.Threading.Tasks. We will shortly add cancellation to Tasks and interrupt dispatching for peripherals. Please take a look at our roadmap and...
  • LLILUM SDK is now available for Visual Studio 2015 August 4, 2015
    We published today the first cut of the Llilum SDK for Visual Studio 2015. The build and installation experience is still a bit cumbersome, but you can now build and debug Llium code entirely in Visual Studio 2015. We also started cleaning up the LLVM bitcode generation by providing a managed wrapper for LLVM3.6.1, fixed...
  • AOT Proof of Concept available for comments July 8, 2015
    We published this morning a Proof of Concept (POC) for applying Ahead of Time (AOT) compilation techniques to MSIL and target MCUs. We will grow this project side by side with .NET Micro Framework 4.4 and eventually integrate the .NET MF stack into the LLILUM tool chain to achieve both a smaller code size and higher execution speed....
  • 4.4 Beta 2 is here! July 6, 2015
    We just released 4.4. Beta, please find it on our Github repo.  With this release we provide major improvements in reliability for the lwIP TCP/IP stack as well as lots of bug fixes. Please check our backlog on the older Codeplex issues list, and if you find that any issue you care about has not been...
