Master WPF is for software developers looking to take their WPF skills to the next level. It is packed with 500 questions designed by WPF expert Josh Smith to provide a broad and deep knowledge of Microsoft's Windows Presentation Foundation.

Master WPF displays questions and answers in a flashcard-like format. The questions are organized by topic. Answer questions at random, or drill into a specific topic that you want to master.

The app tracks your answer history and shows which questions you got right or wrong, haven't answered yet, and the ones marked favorite.

The questions are real-world

Our WPF app had a bug that we were trying to fix for a long time. One of the questions in this app about routed events showed me that we were doing something wrong. I fixed the bug! My team is going to freak out on Monday morning. If that isn't worth five bucks, what is?

Great tool with a good interface

The interface makes me wish I were studying for a test, this would take the edge off. The questions are a great mix, with a combination of accessibility and depth that lets you deepen your current strengths and expand to areas you might not even know exist.

Which WPF app should you download right now?

This app. It's a great way to brush up on things if your rusty, or if you just wanna stay sharp. The most surprising thing about this app? The urge it gives me to press "next question!"
