How do you access podcasts in WP7?

How can you access the list of podcasts on the phone and play them in WP7?

Thanks

Solution

Currently there is no way you can query podcasts. The Genre won't tell you whether the content you are working with is a podcast or not - MediaLibrary will access the regular songs only and not additional content.

Hopefully the Mango update will carry some extensions for the Media Access API.
