Shared source for bluetooth developers
The Microsoft Shared Source Program has released a free, managed-class library for building Bluetooth enabled applications and services for Windows CE and Windows Mobile-based devices. The new library reduces the native Bluetooth code from hundreds of lines to just a few, making development faster and easier, and giving developers more time to create new and innovative applications.
