We’ve released an update to Prism (v 2.1) that refreshes the bits for SL 3.0. You can find the updated MSDN download here.
Most of the changes to this release are minor:
- Projects refreshed to target SL 3.0
- The DelegateCommand and CompositeCommand no longer hold on to the CanExecuteChange handlers.
- The TabRegionControlAdapter was updated to set the context for the Header item to retain the same behavior as the Prism 2.0 version.
You can find more details on the MSDN page.
