.NET is a brand name for a set of modern technologies. Microsoft's .NET is a development platform used to create dynamic websites and Web applications. The .NET Framework is used for building applications that have optimal user experiences. It supports numerous Web technologies, including.
Language Integrated Query (LINQ)
Language Integrated Query (LINQ, pronounced "link") is a Microsoft .NET Framework component. LINQ was introduced in .NET version 3.5 to allow a programmer to query data from many kinds of data sources without knowing any external language. Querying is the process of obtaining data from a data source. LINQ makes it very easy for you to query data from different kinds of data sources. LINQ is integrated to both C# and VB, and multiple special keywords and syntax for querying using LINQ have been added. Before the arrival of LINQ, programmers write different set of codes for querying different data sources.
Windows Presentation Foundation (WPF)
The Windows Presentation Foundation is Microsofts next generation User Interface framework to create applications with a rich user experience. It is part of the .NET framework 3.0 and higher.
WPF combines application UIs, 2D graphics, 3D graphics, documents and multimedia into one single framework. Its vector based rendering engine uses hardware acceleration of modern graphic cards. This makes the UI faster, scalable and resolution independent.
Windows Workflow Foundation (WF)
Windows Workflow Foundation (WF) is one of the parts of the .NET 3.0 framework as released by Microsoft. One of the most interesting aspects of Windows Workflow Foundation (WF) is the separation between business process code and the actual implementation, often a requirement in Service Oriented Architecture (SOA). Before Windows Workflow Foundation the typical scenario would be to write both the business logic and the actual implementation in C#, Visual Basic .NET or another .NET language.
The result was no clear separation between business logic and its implementation. With the release of Windows Workflow Foundation (WF) the business logic can be defined in the workflow while the actual underlying implementation is done in C#, Visual Basic .NET or another .NET language. So basically the what is done in the workflow and the how is done in traditional programming code.
Windows Communication Foundation (WC)
Windows Communication Foundation (Code named Indigo) is a programming platform and runtime system for building, configuring and deploying network-distributed services. It is the latest service oriented technology; Interoperability is the fundamental characteristics of WCF. It is unified programming model provided in .Net Framework 3.0. WCF is a combined features of Web Service, Remoting, MSMQ and COM+. WCF provides a common platform for all .NET communication.
Silverlight is a new cross-browser, cross-platform implementation of the .NET Framework for building and delivering the next generation of media experiences and Rich Interactive Applications(RIA) for the web. It runs in all popular browsers, including Microsoft Internet Explorer, Mozilla Firefox, Apple Safari, Opera. The plugin required to run Silverlight is very small in size hence gets installed very quickly.
Silverlight aims to compete with Adobe Flash and the presentation components of Ajax. It also competes with Sun Microsystems' JavaFX, which was launched a few days after Silverlight.
