wpf ribbon control with custom controls -

This control has been in pre-release, so I was thinking:

1) This product For the application or do you buy third parties?
2) How much do you usually do in your ribbon in code vs. xaml?
3) Can you put custom / user controls in it?
4) Any favorite useful links and / or permission?

Cheers, Beryl

I have found it now Sorry if too many duplicates

I'm using it for mixed applications with an internal app. I use a mixture of XAML and code based on the situation. For example, I load in different menus based on user.

There are some bugs in this that make it dangerous for production use. For example, if you do not set the minimum width on the form at a large enough value, then it gets confused. So, unless it is limited delivery, the internal application will wait at least the next beta.

PS If you hear about a good third party option, please let me know.
