If you were at the Professional Developer Conference in L.A. this week, then you're probably exhausted, suffering from a bit of information overload, and either on your way home or getting ready to head that way. There was a ton of information on so many topics, and thankfully even if you weren't in L.A., you can still watch the sessions online.
I wanted to call out a few sessions that might be of interest to Messaging Developers:
Exchange Web Services Managed API: Unified Communications Development for Exchange - If you use EWS, are thinking about using EWS, or got scared away from EWS by terms like SOAP and WS-*, then you have to watch this session. Jason Henderson lays out the details of a new managed API that will greatly simplify developing code that integrates with Exchange.
Office Business Applications: Enhanced Deployment - The title of this one doesn't capture all of the interesting topics that Saurabh covered. In the process of covering the deployment scenario, he also hit on a lot of the changes that are coming to Office Business Application development (AKA: VSTO) in the next version of Visual Studio, including the removal of runtime dependencies on Primary Interop Assemblies (PIA's).
Microsoft Office Communications Server and Exchange: Platform Futures - This session talked about the future of extensibility for Office Communications Server and Office Communicator as well as the UC functionality of Exchange Server.
