The Microsoft .NET Framework 4 web installer package downloads and
installs the .NET Framework components required to run on the target machine
architecture and OS. An Internet connection is required during the
installation. .NET Framework 4 is required to run and develop applications to
target the .NET Framework 4.
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 .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.
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
SharePoint Server data as an OData feed and access that data feed by using the
WCF Data Services client library. For more information go here.
Enhancements to
ASP.NET
More control over
HTML, element IDs and custom CSS that make it much easier to create
standards-compliant and SEO-friendly web forms.
New dynamic data
features including new query filters, entity templates, richer support for
Entity Framework 4, and validation and templating features that can be easily
applied to existing web forms.
Web forms support for
new AJAX library improvements including built-in support for content delivery
networks (CDNs).

list of enhancements to ASP.NET go here.
Improvements in
Windows Presentation Foundation (WPF)
Added support for
Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
Added support 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.
For a comprehensive
list of enhancements to WPF go here.
Improvements to
Windows Workflow (WF) that enable developers to better host and interact with
workflows. These include an improved activity programming model, an improved
designer experience, a new flowchart modeling style, an expanded activity
palette, workflow-rules integration, and new message correlation features. The
.NET Framework 4 also offers significant performance gains for WF-based
workflows. For a comprehensive list of enhancements to WF go here.
Improvements to
Windows Communication Foundation (WCF) such as support for WCF Workflow
Services enabling workflow programs with messaging activities, correlation
support. Additionally, .NET Framework 4 provides new WCF features such as
service discovery, routing service, REST support, diagnostics, and performance.
For a comprehensive list of enhancements to WCF go here.
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.
