New features and improvements




The .NET Framework 3.5 introduces some new features and improvements that enhance the functionality and usability of the .NET Framework. Some of these features and improvements are:


  • LINQ (Language Integrated Query): LINQ is a set of extensions to the .NET languages that enable you to query data from various sources, such as arrays, collections, databases, XML, and more, using a common syntax and a unified programming model.



  • Lambda expressions: Lambda expressions are anonymous functions that can be used as arguments to methods that take delegates, such as LINQ operators. Lambda expressions make your code more concise and expressive.



  • Extension methods: Extension methods are static methods that can be called as if they were instance methods of a certain type. Extension methods allow you to add new functionality to existing types without modifying them or creating derived types.



  • Anonymous types: Anonymous types are compiler-generated types that have no explicit name and are inferred from the initialization expression. Anonymous types are useful for creating temporary objects that hold a set of properties.



  • Partial methods: Partial methods are methods that have their declaration in one part of a partial class and their implementation in another part of the same partial class or in another partial class. Partial methods allow you to customize the behavior of generated code without modifying it.



  • WCF (Windows Communication Foundation): WCF is a framework for building service-oriented applications that communicate across different platforms and protocols. WCF simplifies the development and deployment of distributed applications by providing a unified programming model and a rich set of features.



  • WPF (Windows Presentation Foundation): WPF is a framework for building rich user interfaces for Windows applications. WPF leverages the power of DirectX and XAML to provide a declarative and flexible way of creating stunning graphics, animations, media, and documents.



  • WF (Windows Workflow Foundation): WF is a framework for building workflow-based applications that orchestrate the execution of tasks and activities. WF provides a graphical designer, a runtime engine, and a set of predefined activities that enable you to model, execute, and monitor workflows.



  • Cardspace: Cardspace is a framework for managing digital identities and providing secure access to online services. Cardspace allows you to create and store personal identity cards on your computer or on a trusted provider, and use them to authenticate yourself to websites that support Cardspace.



  • AJAX (Asynchronous JavaScript and XML): AJAX is a technique for creating dynamic web pages that update parts of the page without reloading the whole page. AJAX enables you to create responsive and interactive web applications that enhance the user experience.



Compatibility and performance




The .NET Framework 3.5 is compatible with most Windows operating systems, including Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10.

The .NET Framework 3.5 also improves the performance of the .NET Framework by optimizing the CLR, reducing memory usage, enhancing startup time, improving garbage collection, and supporting multicore processors.


Support for various platforms and technologies




The .NET Framework 3.5 supports various platforms and technologies that enable you to develop and run applications for different scenarios and devices. Some of these platforms and technologies are:


  • Silverlight: Silverlight is a cross-platform and cross-browser plugin that enables you to create rich web applications that run on Windows, Mac OS X, Linux, and mobile devices. Silverlight uses a subset of the .NET Framework 3.5 called the Silverlight CoreCLR.
