Microsoft announced that parts of the MFtoolkit  will be available in the first service pack for .NET Micro Framework 3.0. Missing http support (currently we have only simple WebServices) is one of the most requested features. Support for hardware devices / modules like XBee or common sensors are following right after. .NET MF 3.0 SP1 will be available around June 2009.
Until then the MFtoolkit  will be still available at CodePlex . This week we got some new features like NetBIOS lookup, C6820 camera driver, SHA1 and SHA256 support as well as more improvements for XBee and http server classes.
