Windows Presentation Foundation, a Development Tool for Web Applications
Windows Presentation Foundation (WPF) in Visual Studio is Microsoft's tool used for development of rich client and Web applications. WPF primary goal is to help developers create effective and attractive user interfaces. Windows Presentation Foundation is based on .NET framework and was first introduced by Microsoft as a part of .NET 3.0. WPF combines UI, 3D graphics, 2D graphics, multimedia, and documents processing technologies into a single framework that allows developers to create interactive applications with immersive and intuitive user experiences.
Windows Presentation Foundation separates the UI from the rest of the implementation as much as possible. With WPF system, developers can separate visual behavior from the program logic. WPF provides a unified API and different additional tools for creating complex UIs.
The WPF’s biggest innovation is XAML, the Extensible Application Markup Language. The XAML code describes the control objects and their specific properties that make up the UI. It is a new file type and a new language that presents a declarative model for application development and allows developers to create 3D images, graphics, animations, and custom controls. With XAML, programmers can create a specific workflow where separate groups can work on the logic of an application the UI and use potentially different tools.
Windows Presentation foundation helps developers and designers work together. Usually, designers use graphical tools to create static images of the screen layouts and give the images to developers whose task is to write the code that makes them real. But sometimes, technology limitations, lack of skills, schedule pressures, misunderstandings, or some other obstacles might prevent developers from fully accomplishing the designers’ visions.
The Extensible Application Markup Language solves this problem. XAML determines a set of XML elements to explain exactly how a UI looks and does it in a tool-friendly way. Designers can specify UI features using Microsoft Expression Blend and developers can import that XAML description into Microsoft Visual Studio where this interface definition is adopted. This results in faster turnaround and a product of a better quality.
