The Microsoft .NET Framework is a software framework that can be installed on computers running Microsoft Windows operating systems. It includes a large library of coded solutions to common programming problems and a virtual machine that manages the execution of programs written specifically for the framework. The .NET Framework is a Microsoft offering and is intended to be used by most new applications created for the Windows platform.

In this articles we talk about Microsoft .NET Framework 4.0

What’s new in .NET Framework 4.0?

1. Next versions of Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF) will provide better support for Web 2.0 technologies like REST, POX, and ATOM.

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

1. Simplifying the building of REST Singleton & Collection Services, ATOM Feed and Publishing Protocol Services, and HTTP Plain XML Services using WCF
