Forgot to add: all the app blocks that we are shipping now are EntLib spec compliant, including the Smart Client blocks like Updater. That means the user experience should be far more consistent than it was in the past.
For example, Updater uses the configuration settings, tools, etc. EntLib provides. But also, the block will have the same documentation structure, VS.NET integration, et al. of EntLib.
We expect this to be a big enhancement in the usability of our assets, please send us feedback!
