SOA
Without a doubt the message I heard yesterday was Service Oriented Architecture. Granted 3 out of 4 sessions I attended were part of the Connected Services Track. Although even the Developer Session (Software Reuse with .NET: Best Practices) hyped it up the whole talk too. It makes me think how much my shop needs to adapt.
Clemens Vaster takes my vote for the best session of the day with his presentation on Best Practices for Dealing with State at Multiple Layers within Your .NET Applications.
Other Highlights:
1. WSE 2.0 is available. WS-Policy, WS-SecureConversation, WS-ReliableMessage, etc.
2. MTOM is the future of DIME.
3. ASMX
4. System.Messaging
5. JITA Proxy Pooling --> See Clemens Vasters blog
