hi friends,
The difference between framework 3.0 and framework 4.0 are given below.


.NET Framework 3.0

The only update to this version (from 2.0) is the inclusion of the following technologies:
Windows Communication Foundation (WCF). Important to follow this technology if you are into developing service-oriented applications.
Windows Presentation Foundation (WPF) . If you are mostly developing web applications, you probably will not be needing this.
Windows Workflow Foundation (WF).
Windows Cardspace.
.NET Framework 3.0 did not come with any version of Visual Studio. But .NET Framework 2.0 did and it came with Visual Studio 2005



.NET Framework 4.0

The following are what’s new in this version:
In-Process Side-by-Side Execution which allows you in your application to load and start multiple versions of .NET Framework in the same process.
Application Domain Diagnostics and Performance Monitoring which allows you to monitor all application domains in the process, not just the process itself.
Parallel Computing which allows you to write efficient, fine-grained, and scalable parallel code in a natural idiom without having to work directly with threads and thread pool.
The rest of the changes are mostly improvements on .NET Framework 3.5.
.NET Framework 4.0 was released with Visual Studio 2010.
For a complete list of what’s new in 4.0, go to this link.
