Why Bus Filter Framework?

Writing a KMDF driver is much more easier than writing a WDM one. Once you start to do it in the KMDF way, you will never ever want to go back to WDM!

In spite of so many advantages, KMDF has a drawback: It does not support bus filters, officially. The only way to create bus filters was to do it in a WDM manner.

Ever since KMDF was born, people have been asking the question: How can I write a bus filter driver with KMDF? Yet, the answer was disappointing...until now! I present you Bus Filter Framework, or BFF for short! With BFF, you can create bus filters with your beloved KMDF! Say good-bye to WDM from now on!
