The .NET Framework is Microsoft's comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes.

The Microsoft .NET Framework 4 redistributable package installs the .NET Framework runtime and associated files that are required to run and develop applications to target the .NET Framework 4.

The .NET Framework 4 works side by side with older Framework versions. Applications that are based on earlier versions of the Framework will continue to run on the version targeted by default.

.NET Framework 4 includes the following new features and improvements:
-  Improvements in CLR and BCL
-  Improvements in ADO.NET
-  Enhancements to ASP.NET
-  Improvements in Windows Presentation Foundation
-  Improvements to Windows Workflow Foundation and Windows Communication Foundation
