Earlier Versions of Windows Mobile
On devices running versions of Windows Mobile earlier than version 5.0, these managed class libraries are not available. To include some of the functionality, you can PInvoke the native APIs or use a third-party wrapper. Mobile In The Hand (www.inthehand.com/WindowsMobile.aspx) provides a subset of the Windows Mobile 5.0 managed APIs that works on devices running Windows Mobile 2003 and later. This library can make it easier to write a single set of code across a wider range of devices. A free community edition that provides the basic functionality from the Configuration, PocketOutlook, Status, and Telephony namespaces is available.
