I am entirely new to WPF . Though I am going thru the tutorials and articles from net but I am having doubts . Some of the questions which have striked out so far are

a) What is routed events and what extra thing it does server?

b) What are dependency properties and it's benefits.

c) How dependency properties differ from attached properties.

d) Why does first bubbling happens follwed by tunneling? And what is the purpose of this?

e.g.

<canvas>

       <button canvas.left=10/>

    </canvas>

Is it a dependency property or attached property?

Thanks
