PRISM project:

I'm trying to add  views (usercontrols) to a TabGroupPane in XamDocManager. I'm getting errors about the control type, and am guessing that I need a RegionAdapter for this. For doing something similar with XamRibbon, I created a RibbonRegionAdapter (not with NCAL). Now, I want to explore NCAL. Can someone tell me why specifically I should use NCAL. And does NCAL have the other RegionAdapters I will need? Specifically for TabGroupPane.

Is the project on CodePlex the only sample projects available for NCAL? Or does Infragistics provide any? Also, why is NCAL not supported from Infragistics?

Thanks in Advance.
