.NET Micro Framework
Una versión aun más reducida que el .NET Compact Framework para desarrollar aplicaciones para una gama más amplia de dispositivos.
The .NET Micro Framework brings a rich, managed-code environment to smaller, less expensive, and more resource-constrained devices. Requiring only a few hundred kilobytes of RAM and an inexpensive processor, the .NET Micro Framework was built from the ground up to let you build applications using familiar Visual Studio development tools.
The .NET Micro Framework extends Microsoft’s offerings for creating embedded systems by providing a managed-code environment focused on small devices. It brings a new level of efficiency and reliability to embedded devices that don’t need the advanced capabilities of Windows® XP Embedded or Windows CE with the .NET Compact Framework.
