Our partners in crime over in the p&p smart client program have just released the October Community Technology Preview (CTP) of the Composite UI Application Block. For those EntLib fans in the audience (especially those who like to get "down and dirty" in the internals), one piece of the new CTP that you may want to start looking at is ObjectBuilder. This is a new shared component that will also be appearing in the final release of Enterprise Library for .NET 2.0 - it provides dependency injection services that we're using to make our configuration system more flexible. If you don't know (or care) about dependency injection, don't worry - it will still be possible to use EntLib in the same way you do today. But if you're into that kind of thing, ObjectBuilder should be a fun new toy to play with. And of course, the rest of the Composite UI block is well worth a look too!
