Some of the most important areas focused in .NET Framework 4.0 are as below

Parallel Computing

- For parallel computing Parallel Extensions are provided. which target multi-core or distributed systems.

- The plan is also to include technologies like PLINQ (Parallel LINQ). which is the parallel implementation of the LINQ engine,

- Task Parallel Library, which exposes parallel constructs via method calls

Apart from this

- Full support for IronPython, IronRuby,

- Support for a subset of the .NET Framework and ASP.NET with the “Server Core” variant of Windows Server 2008 R2

- Support for Code Contracts.

- Oslo modeling platform, along with the M programming language.

In conjunction with .NET Framework 4.0, Microsoft will offer a set of enhancements, codenamed Dublin, for Windows Server 2008 application server capabilities.
Work Flow (WF) Improvements:

Explicit data model and fully declarative experience for authoring activities,
A new Flowchart modeling style
Deeper integration with Windows Communication Foundation (WCF)
High performance runtime engine

Significant improvements in performance and scalability

Ten-fold improvement in performance

New workflow flow-control models and pre-built activities

Flowcharts, rules
Expanded built-in activities – PowerShell, database, messaging, etc.

Enhancements in workflow modeling

Persistence control, transaction flow, compensation support, data binding and scoping
Rules compos sable and seamlessly integrated with workflow engine

Updated visual designer

visual designer is easier to use by end-users
visual designer is easier to re host by ISVs
visual designer has ability to debug XAML

WCF introduced support for REST-style communications in .NET Framework 3.5. The features involved were

Developers can specify URL Templates on Operation Contracts, to allow methods to be invoked when requests on specific URLs are received.
Parameters from the URLs can be automatically extracted and passed to the method. JSON and plain-old-XML data serialization is supported;
Alternative mechanisms for binary return types.

Current Enhancements

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

Messaging enhancements

Transports – UDP, MQ, Local in-process
Protocols – SOAP over UDP, WS-Discovery, WS BusinessActivity, WS-I BP 1.2
Duplex durable messaging
Content and context driven, One-way support

Declarative Workflow Services

Seamless integration between WF and WCF and unified XAML model
Build entire application in XAML, from presentation to data to services to workflow

Multi-Targetting

Using multi-targeting gives user a benefit to use the current version of Visual Studio to create and develop projects that target earlier versions of the .NET Framework. For applications that use either WCF or WF, they will also extend IIS to be the “standard host”
