.NET Micro Framework
Overview
The original .NET for embedded systems. Works as expected on the GHI Electronics hardware you know and love.
- Visual Studio 2013
- NETMF 4.3
- NRND
NETMF history
.NET Micro Framework (NETMF) is a subset of the full .NET Framework. This framework is no longer active — it’s been replaced by the more modern and more secure TinyCLR OS.
Longevity Commitment
While the NETMF operating system is no longer active, the GHI Electronics NETMF SoMs and SoCs are still in production in accordance with our longevity promise. Customers should consider upgrading to the SITCore (Secure IoT Core) product family.
