Overview
The Microsoft .NET Framework 4 Client Profile provides a subset of features from the .NET Framework 4. The Client Profile is designed to run just client applications and to enable the fastest possible deployment for Windows Presentation Foundation (WPF) client applications and Windows Forms client applications. Application developers who require features that are not included in the Client Profile should target the full .NET Framework 4 instead of the Client Profile.
The .NET Framework 4 works side by side with the Framework version 3.5 SP1. Applications that are based on earlier versions of the Framework will continue to run on that version. Just a subset of functionality is shared by all versions of the Framework.
The ADO.NET Entity Framework, which simplifies how developers program against relational databases by raising the level of abstraction, has many new features. These includes persistence ignorance and POCO support, lazy loading, test-driven development support, functions in model, and new LINQ operators.
Improvements in WPF:
Added support in Windows Presentation Foundation (WPF) for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
Added support in WPF for Surface 2.0 SDK.
New line-of-business controls including charting control, smart edit, data grid, and others that improve the experience for developers who build data centric applications.
Improvements in performance and scalability.
Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.
Limited support for communicating using Windows Communication Foundation (WCF).
Innovative new parallel-programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordination data structures which let developers harness the power of multi-core processors.
