Microsoft''s .NET Micro Framework Software Developers Kit (SDK) integrates with Visual Studio 2005, enabling SPOT devices developers to work in C# in a managed code environment.

At Embedded World 2007 in Nuremberg, Germany, Microsoft announced it is shipping a developers' kit for the smallest of its device systems.

The .NET Micro Framework grew out of Microsoft's Smart Personal Objects Technology (SPOT) initiative, which was designed to support very small, embedded devices that do not have the resources to run a more full-function system such as Windows Mobile.

Microsoft's .NET Micro Framework Software Developers Kit (SDK) integrates with Visual Studio 2005, enabling SPOT devices developers to work in C# in a managed code environment, company officials and Microsoft documents said.

The Micro Framework also provides extensible hardware emulation and realtime debugging capabilities, including support for devices built on the ARM7 and ARM9 microprocessors.

Watches, weather stations, and GPS (Global Positioning System) units are among the SPOT devices that have debuted, though Microsoft sees far more uses for such small embedded systems such as in robotics applications (see Resources).

The .NET Micro Framework is not the same as Microsoft's .NET Compact Framework. The Compact edition is designed to support much more powerful devices such as wireless phones running Windows Mobile. Microsoft just announced that it will ship Windows Mobile 6 this spring (see Resources).

A minimum of 256KB RAM and 512KB Flash/ROM is required for development and deployment. Other requirements for development include Windows XP, Windows Vista, or Windows Server 2003 along with Visual Studio 2005 (either Standard or Professional edition). It also requires a 600 MHz Pentium processor (1 GHz Pentium processor recommended) and 6 MB of free hard-disk space.

Microsoft's .NET Micro Framework SDK is available here.

    At the Visual Studio Live! @ Microsoft HQ developer conference set for August, Rockford Lhotka will explain the ins and outs of authentication across Blazor Server, WebAssembly, and .NET MAUI Hybrid apps, and show how to use identity and claims to customize application behavior through fine-grained authorization.

  • Linear Support Vector Regression from Scratch Using C# with Evolutionary Training

    Dr. James McCaffrey from Microsoft Research presents a complete end-to-end demonstration of the linear support vector regression (linear SVR) technique, where the goal is to predict a single numeric value. A linear SVR model uses an unusual error/loss function and cannot be trained using standard simple techniques, and so evolutionary optimization training is used.
