Differences between XP and Vista WPF?

First, hello everyone!

This is my first post here, so please be gentle.

On to my question;

Does anyone know how deep the differences are between XP WPF and Vista WPF implementations?

For instance, I know that 3D in XP WPF does not implement anti aliasing, yet Visa does. Is there anything else?

At the moment, I have no agenda or software I want to produce using WPF. I just want to know if there are any caveats I should avoid.

Thanks in advance to taking the time to post,
