Starting work on Prism 4.1

  • Article

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.

    We finished development and are currently testing the fixes. we should finish by the end of the month and hopefully sooner.For those of you that need to Prism earlier, have you recompile the library with Silverlight 5? It should work fine for you. If not let me know.

    Yesterday Bob Brumfied posted our current Prism for SL5 source code to codeplex. For those that need to get started with SL5 this is a good starting point. This code includes support for SL5 and some of the bugs listed above. We have not finished testing all of the bugs which should be done by the end of January.

    Prism 4.1 will out be next week. We had some delays in getting our test team to test the bits which is why it is not out yet. We are going through our final tests this week and will publish it next week. Sorry about the delays.

    Seems Prism 4.1 share same documents with 4.0. You can find some additional document content form the 4.1 Readme file.

    mp, the binaries are not going to be available on codeplex. I updated the home and download pages to provide a link to where you can download the binaries. I just blogged about Prism 4.1 which confirms Timothy Liu's point above on the documentation. Thanks Timothy.

    Could you add 8927 to the list? It takes only 4 lines of code to fix scoped region limitation for navigation and view discovery. Please see the comments in the work item.

    When Prism 4.5 arrives, will code that has been developed on 4.1 still work? We are new to Prism, and are wondering about Prism's track record in upwards compatibility.The subtext for this question is really this: for applications built on Prism (and in our case, we're talking HUGE scale engineering apps), how much impact can we expect as subsequent Prism versions are rolled out? Barely a ripple (complete upward compatibility) or major breakage?

    Very concerned that the latest this forum has been update is Feb 2012. Is this development framework still supported? January is a long way away.  Anyone know of alternatives? We're considering jumping ship to something with support for .Net 4.5 now.
