Networking a .NET MF device previously required calling through to an underlying operating system with sockets support, according to Microsoft. Version 2.5 now provides a stack that is available even when running directly on the hardware. Since device makers need only provide a driver for the network interface, a wider selection of network-capable hardware development platforms will be available, the company says.
Microsoft adds that the new version of .NET MF will also include client and server support for
Web Services on Devices, also known as Device Profile for Web Services (DPWS). Already part of Windows Vista and
Windows CE 6.0 Release 2, this "enables a USB-like level of plug-and-play for networked devices," in the company's words. DPWS-enabled devices on a network can discover one another, then invoke the functionality each device provides.

Microsoft
first released .NET Micro Framework (.NET MF) in 2006, aiming it at wireless remote controls, watches, and other cost-sensitive devices with constrained processor and memory resources. The .NET MF grew out of Microsoft's
Smart Personal Objects Technology (SPOT) initiative, with embryonic versions variously dubbed
.NET Embedded and
TinyCLR.
According to Microsoft, .NET MF supports low-end embedded processors and doesn't require an MMU (memory management unit). A typical runtime image is only about 300 KB in size, the company says.
AvailabilityThe .NET Micro Framework, version 2.5, is available now, according to Microsoft. It is being demonstrated this week at the
Embedded World 2008 show, in Nuremberg, Germany, in the Microsoft Windows Embedded booth (hall 11, stand 318).
