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).
- For a comprehensive 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.
