Hi,
<Then, if you "navigate away" from your views in that type of region, the views would still be active and the RegionMemberLifetimeBehavior will not try to check their KeepAlive property.

I will try this.
My App has Regions for SubMenu(depending on Module), Toolbar's, and 3 Regions for Menu's so that every Module can have it's own Toolbar's and menu's etc
Now, i try to handle all this stuff of adding and removing Toolbars and Menu's from Regions by using the INavigationAware and IRegionMemberLivetime Interfaces.
The reason for this is, i think that i have now trouble with cleaning up my Regions when a Module is changed.
