I'm glad I got into this just two weeks ago instead of earlier. I came in at an exciting time.
I like how you can extend existing xaml objects and created new ones.
I was looking for an RSSView button that would tie into the common feeds list that I can set sizing, etc attribs for. I haven't decided whether to extend an existing object or create a new one, the great thing is I can and it's not difficult.
Is the IxFeedsManager and IFeedsManager going to change or does it look like it's make it into the final .NET 3.0?
