“OpenNETCF.org Bluetooth is a managed Bluetooth networking library for Windows Mobile, Windows CE and Windows XP devices running the Microsoft Bluetooth stack. Supports client and server connections and device discovery using an object model which will be familiar to developers who have used the IrDA and Tcp equivalent. The package contains the full source of the project, a number of sample apps covering the different target platforms and help files which integrate into Visual Studio. You must have either Visual Studio 2003 or Visual Studio 2005 Beta2 to access the help and make full use of the library.”
