Prism 2.1 (Composite Application Guidance for WPF & Silverlight 3) just released (updated version for Silverlight 3)
November 2nd, 2009
The patterns & practices team has just released Prism-v2.1, an updated version of the Composite Application Guidance for WPF & Silverlight, which has some breaking changes, mostly related to Silverlight 3 (from the “New in this release” article):
- All Visual Studio projects (Composite Application Library, reference implementation, and Quickstarts) were migrated to use Silverlight 3.
- TabRegionControlAdapter was modified to support binding in the TabItem’s control header in Silverlight 3.
- CreateXap.bat file was modified to search for Silverlight 3 assemblies if the Silverlight 2 reference assemblies cannot be found.
- Implemented the WeakEvent Pattern for the DelegateCommand’s and CompositeComand’s (more on this below).
If you were using Prism 2.0, either for WPF or Silverlight development, I would recommend you to start using this new version, as there is also an implementation “of the WeakEvent Pattern for the DelegateCommand’s and CompositeComand’s CanExecuteChanged event to fix a possible memory leak in the applications using the Composite Application Library commands”.
You can download the latest version of the guidance from here.
Kudos to the Prism team!!!
