Chapter 2. Windows Driver Foundation (WDF) Architecture > Driver Frameworks
2.9. Driver Frameworks
The WDF driver model is implemented through the KMDF, which supports Kernel Mode Driver development, and the UMDF, which supports User Mode Driver development. The frameworks provide the basic driver infrastructure and perform the following services for WDF Drivers:
Define WDF objects that drivers can instantiate.
Manage object lifetimes.
Expose a basic set of DDIs that drivers call to manipulate the objects.
Provide a common implementation of features that drivers typically require, such as Plug and Play, power management, synchronization, I/O queues, and access to the registry.
Manage the flow of I/O requests and Plug and Play and power notifications from the operating system to the driver.
