More open-source goodness. A managed wrapper for the BTObex library. The source includes the BTObexWrapper.h header file which contains the wrapper code (shown below) and a compiled managed DLL, for those who just want to include it into their projects and use it ASAP.

// Managed C++/CLI wrapper for the BTObex Library
// Include the BTObex library files into the project (BTOBEX sub-directory) and compile as a managed DLL
