2. Performance and Scalability of WCF and WF are expected to increase by minimum 10X.


3. New workflow models.


4. Seamless integration between WCF and WF including a new Visual Designer.


5. Parallel Programming framework using PLINQ, Task Parallel Library and Coordination Data Structures to better utilize power of multi-processor and multi-core machines.


6. Build declarative applications with WF, WCF and WPF using XAML. So, XAML is no more only for WPF and WF.


7. WCF enhancements:


1. RESTful enhancements
