When was wpf released

Resolution Independent Another feature of WPF is Resolution Independence which allows text and graphical elements to be resized without affecting the layout or clarity of the items.

This means that elements can be made larger and therefore accessible to people with visual impairment. Large items, such as buttons, icons and menus, are also easier for people with physical difficulties to target using their trackball, joystick or other pointing device. Animations and timelines Windows Presentation Foundation WPF provides a powerful set of graphics and layout features Animation that enables you to create attractive user interfaces and appealing documents.

Animation can make an attractive user interface even more spectacular and usable. By just animating a background color or applying an animated Transform, you can create dramatic screen transitions or provide helpful visual cues. WPF supports time-based animations, in contrast to the frame-based approach.

This decouples the speed of the animation from how the system is performing. It also supports low level animation via timers and higher level abstractions of animations via the Animation classes. WPF has a built-in set of data services to enable application developers to bind and manipulate data within applications. It supports three types of data binding: One time: Where the client ignores updates on the server.

One way: Where the client has read-only access to data. Two way: Where client can read from and write data to the server. You can define almost any type of control as content of another. Although this flexibility sounds horrible to designers, it's a very powerful feature if you use it appropriately.

Put an image into a button to create an image button, or put a list of videos into a combo box to choose a video file. XPS Document Windows Presentation Foundation WPF offers a wide range of document features that enable the creation of high-fidelity content that is designed to be more easily accessed and read than in previous generations of Windows.

One type of a new featured document is XPS. This provides an avenue for displaying more complex graphics and custom themes, at the cost of GDI's wider range of support and uniform control theming. It allows Windows to offload some graphics tasks to the GPU. This reduces the workload on the computer's CPU. GPUs are optimized for parallel pixel computations; this tends to speed up screen refreshes at the cost of decreased compatibility in markets where GPUs are not necessarily as powerful, such as the netbook market.

WPF's emphasis on vector graphics allows most controls and elements to be scaled without loss in quality or pixelization, thus increasing accessibility. There are various situations in which UI skinning might be important for an application. It can be used to allow the end-user to customize the UI based on his or her personal aesthetic preferences. Another scenario in which skinning might be used is when a company creates one application that is subsequently deployed to various clients.

Each client might want their company logo, colors, font, etc. If the UI is designed with skinning in mind, that task is easy to accomplish with minimal effort. Multimedia Support Windows Presentation Foundation WPF provides support for multimedia, vector graphics, animation, and content composition, making it easy for developers to build interesting user interfaces and content.

It allows forms to be created using syntax very similar to ASP. DirectX allows to offload graphics tasks to the GPU. This frees up the CPU to do other work and thus increases app performance. Dependency Properties: WPF introduces a new type of property called a dependency property. A dependency property depends on multiple providers for determining its value at any point in time. The value of a DependencyProperty is resolved dynamically. Major advantages of dependency properties are reduced memory footprint, value inheritance and change notification.

Data binding: Data binding is the process that establishes a connection between the application UI and the business logic. Using data binding we can take data from almost any property of any object and bind it to almost any other dependency property of another object.

Templates and Styles: WPF gives us an extensibility model based on templates and styles, allowing us to perform complex changes and redefinitions of the visual appearance of a control, without having to create a new one. You can change the structure and appearance of a control by modifying the ControlTemplate of that control. A Style object is a collection of values representing properties for the specified control. Ability to cache images: You now have the ability to cache images that are downloaded over HTTP to the local Microsoft Internet Explorer temporary file cache, so that subsequent requests for the image come from local disk, rather than the Internet.

Depending on the sizes of your images, this can be a significant network performance improvement. Interactive 2-D Content on 3-D. New Transformation Services. Enhanced Data Binding: A new debugging mechanism makes it easier to debug data bindings. The data model enables validation on the business layer by providing support for the IDataErrorInfo interface.

In addition, the validation model now supports using property syntax to set validation rules. The property gets the TextSelection that represents the selected content in the document. Annotations Improvement: The annotations framework now exposes the capabilities for matching annotations with the corresponding annotated objects. A new interface, IAnchorInfo, has been added. Improved performance for Bitmap effects and faster startup.

New WebBrowser control. Additional functionality includes better support for line of business applications, native splash screen support, DirectX pixel shader support. For more information, please have a look at What's New in the. NET Framework Version 3.

Multi Touch and Manipulation enables you to create applications that receive input from multiple touches simultaneously on Windows 7. Graphics and animation supports layout rounding, Pixel Shader version 3. New types in the System. Shell namespace enable you to communicate with the Windows 7 taskbar and pass data to the Windows shell.

VisualStateManager supports changing states of controls. Text has improved text rendering and supports customizing the caret color and selection color in text boxes. Binding is supported on the Command property of an InputBinding, dynamic objects, and the Text property.

New Ribbon control , which enables you to implement a ribbon user interface that hosts a Quick Access Toolbar, Application Menu, and tabs. Ability to set the amount of time that should elapse between property changes and data source updates. NET Core platform.

NET Framework are set goals in regards to the release of. The roadmap also states that there needs work to be done in order to have all components available and that they are working on the process of how to validate and merge community pull requests. With the upcoming release of.

That also gives you the opportunity to ship a specific version of the. It is a big statement from Microsoft to move WPF to. NET core. NET platform. They invest a lot of money into open-sourcing it and making it run on. One of the biggest benefits of this move is that you are no longer boxed into the full. You now have the same choice for front-end products that backend developers already had since. NET core 1. You can now choose if you want to write your application for the new or the established platform.

Having a choice is great. NET core platform. That is somewhat unintuitive because. NET core is best known as a cross-platform framework, but makes sense if you think about the history of WPF.

Do we have to migrate existing applications to. NET Core? Microsoft suggests that new projects should be considered building on the new. NET Core platform where existing legacy apps which are in maintenance mode and are not business critical can remain on.

NET Framework. The full. NET framework will still be available for a long time. Your application runs on the newest. NET technology which was written from scratch resulting in a much better performance.

Some of the legacy stuff from the early days that could not be removed from the full. NET Framework were not transferred to the. All of this makes it much more efficient.

You can run your applications side-by-side using different. NET Core versions. That allows your application to be independent of the. You gain access to the newest features in Visual Studio around the new project file format, tools and SDKs which were created for applications using the. That is especially helpful in regards to continuous integration and continuous delivery. From the. NET Framework apps that there is no pressure to port them to. NET Core. We will be adding features to.

NET Framework 4. While we do recommend that new desktop apps should consider targeting.
