• Localization improvements include two-way text, right-to-left support, and more than 30 new languages with complex texts such as Arabic, Hebrew, and Thai.
• . Net universal Runtime (CLR) now enables the same compiled code to run on the desktop and Silverlight without any changes.
• Improved data binding improves flexibility and productivity through Data grouping/editing and string formatting.
• Managed extensibility framework (MEF) supports creating large and complex applications.
• The extension tool that supports Silverlight is added in Visual Studio 2010. This includes a complete editable design interface, drag-and-drop Data Binding, automatic control binding, data source selection, integration with expression blend style resources, Silverlight project support, and complete smart sensing.

Development tools have also been improved:

• A fully editable design interface that depicts controls and la S.
• A grid control with rich attributes and a new editor for values.
• Supports data binding and automatic creation of binding controls, such as ListBox and DataGrid. A new data source window and Selector are available.

• Built-in project support for Silverlight applications.
• Fully intelligent editor for XAML, C #, and VB.

The list of new features provided to create truly rich applications is quite long:

• The smooth interface improves the availability of applications through animation effects.
• Supports network cameras and microphones to allow video and audio sharing, such as for chat or customer service applications.
• The local recording capability of audio and video allows you to capture raw videos without requiring interaction with the server. This allows a wide range of end-user interaction and communication scenarios, such as video conferencing.
• Add data with copy, paste, or drag to your application.
• Now you can scroll the long list easily with the mouse scroll.
• Supports regular desktop interaction with new features such as right-click environment menu.
• Support for Google Chrome.
• Performance optimization, which means that the Silverlight 4 Application can be started faster and run twice as fast as the Silverlight 3 application.
• Improved deep scaling, including hardware acceleration to support larger datasets and faster animations.
• Multi-touch support to support some gestures and touch interactions, which will bring a better user experience.
• Multicast Network (Multicast networking) allows enterprises to reduce the cost of stream broadcast events, such as corporate meetings and training.
• Uses the Silverlight DRM provided by playready to provide content protection for H.264 media.
