The Microsoft. NET Framework 4 provides the following new features and improvements Improvements in Common Language Runtime ( CLR) and Base Class Library ( BCL)- Performance improvement including better multicore support, background garbage collection, and profiler attach on server.- New memory mapped file and numeric types.- Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.- For a comprehensive list of enhancements to CLR and BCL go here.* Innovations in the Visual Basic and C languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.* Improvements in Data Access and Modeling- The Entity Framework enables developers to program against relational databases using. NET objects and Language Integrated Query ( LINQ). It has many new features, including persistence ignorance and POCO support, foreign key associations, lazy loading, test-driven development support, functions in the model, and new LINQ operators. Additional features include better n-tier support with self-tracking entities, customizable code generation using T4 templates, model first development, an improved designer experience, better performance, and pluralization of entity sets. For more information go here.- WCF Data Services is a component of the. NET Framework that enables you to create REST-based services and applications that use the Open Data Protocol ( OData) to expose and consume data over the Web. WCF Data Services has many new features, including enhanced BLOB support, data binding, row count, feed customization, projections, and request pipeline improvements. Built-in integration with Microsoft Office 2010 now makes it possible to expose Microsoft Office Share Point Server data as an OData feed and access that data feed by using the WCF Data Services client library.

A redistributable package which installs the. NET Framework runtime and associated files that are required to run most client applications Microsoft. NET Framework 4 Client Profile is a redistributable package which provides only a few features of the. NET Framework 4, and it has been developed specifically to enable fast deployment for WPF ( Windows Presentation Foundation) and Windows Forms apps. Setup process and support for 64 bit systems It comes in the form of an EXE which you have to run, just like any other utility. However, if Microsoft. NET Framework 4 is already part of your operating system, the installation process will not run. In addition to that, you should know that unlike older versions, this. NET Client Profile can be installed on both 86 and 64 bit architectures. Better garbage collection and debugging This package comes with improvements in a lot of areas, including CLR ( Common Language Runtime BCL ( Base Class Library Data Access and Modeling, WPF and Windows Workflow, and the list goes on. To be more precise, now the concurrent garbage collection method is replaced with a background one, while debugging is much easier, including dump debugging, Watson minidumps and mixed mode debugging for 64 bit and code contracts. Improvements in multi-core support, WCF and WPF Better multicore support is provided, as well as better n-tier support with self-tracking entities, customizable code generation (with T4 templates foreign key associations and test-driven development support. When it comes to WCF Data Services ( Windows Communication Foundation) has also received some improvements, such as data binding, row count, feed customization and a better request pipeline. Windows 7 multi-touch, ribbon controls, taskbar extensibility features and support for Surface 2.0 SDK are some of the enhancements Windows Presentation Foundation has received. Bottom line.
