Chapter 4: Overview of the Driver Frameworks

Overview

WDF consists of two frameworks-UMDF and KMDF-to support user-mode and kernel-mode drivers. Although both frameworks share fundamental design principles, the implementation details for the two frameworks and the associated drivers are quite different. With two frameworks to choose from, driver developers must decide which framework to use to implement a driver for a particular device. This chapter discusses how the two frameworks are implemented, how drivers work within each framework, and the types of devices that each framework supports, including some guidelines for choosing the best solution for each device type.
