patterns & practices started working on Prism 4.1 which will target Silverlight 5 and items requested on Codeplex. The current plan is to ship the release in January. Additionally, we plan to ship Prism 4.5 after .NET 4.5 is released. Prism 4.5 will address other highly voted on Codeplex issues.
For Prism 4.1, we will timebox the project and get as many of these items completed as can fit in our timeframe. We are considering the following:
5495 – Event to Command 4052 - Change Constraint for CommandBehaviorBase for WPF 7381 - UpdateRegionsException when adding/removing a view with a scoped region manager 3896 - RegionManagerRegistrationBehavior never stop monitoring the RegionManager 8061 - Sync ActiveAware state of views throughout scoped regions 4730 – SL3 caching not working with Modules 5657 - Remove view does not remove all sub-views 2465 - Exception message - RegionAdapterMappings.GetMapping 7224 - Mef and Module Dependencies in Silverlight 3862 - Bug in Default RegionContext Binding Behavior
Let us know if there are other items that you think we need to address now.
