Multi-threading & Parallelism

Parallel Extensions is a .NET Library that supports declarative and imperative data parallelism, imperative task parallelism, and a set of data structures that make coordination easier.

Protocols - SOAP over UDP, WS-Discovery, WS-BusinessActivity, WS-I BP 1.2Duplex durable messaging

RESTful enhancementsSimplifying the building of REST Singleton & Collection Services, ATOM Feed and Publishing Protocol Services, and HTTP Plain XML Services using WCF WCF REST Starter Kit released on Codeplex to get early feedback

Correlation enhancementsContent and context driven, One-way support

Seemless integration with Workflow Services

Workflow Foundation 4.0XAML-only workflows are the new default

Unified model between WF, WCF, and WPF

Extended base activity libraryMore activities will be present on CodePlex

WF 4.0 simplifies data flow by adding:Arguments, variables, and expressions

Significant improvements in performance and scalabilityNew FlowChart WorkflowImproved WF 4.0 designer / Designer Rehosting

WF 4.0 Basics

demo

WCF and WF

There is great potential in WF + WCF.NET 3.0 didn't provide any integration.NET 3.5 added initial WCF support.NET 4.0 is investing heavily in this area

Workflow Services !!!Think "WCF on the outside, WF on the inside"

WCF exposes external interfaceWF describes internal flow & state transitions
