Developing Drivers with the Windows Driver Foundation (Pro Developer)

Overview

To create a UMDF driver, you must use a number of COM objects that belong to the UMDF runtime and implement a number of COM-based callback objects. Although COM-based applications have a reputation for being large, complex, and difficult to implement, much of this complexity is imposed by the COM runtime and the requirements of applications; it is not intrinsic to COM.

UMDF uses only the essential core of the COM programming model-and does not use the COM runtime-which keeps UMDF drivers lightweight and relatively easy to implement. This chapter provides a basic introduction to using and implementing COM objects, as required by UMDF. It is especially intended for kernel-mode driver developers with limited COM experience.
