Microsoft introduced WPF in 2006 as part of the .NET Framework 3.0. It aims to provide a vector-based graphics system that can produce rich user interfaces resembling those of desktop applications.
WPF applications are built using Extensible Application Markup Language (XAML), a markup language that allows developers to create application UI declaratively. The separation of UI definition from application logic using XAML simplifies UI development.
WPF provides a comprehensive set of application development features that include:
Resolution independent graphics system
Animations
Data binding
Templates
2D/3D graphics
Documents
Media playback
Text handling
Typography
These features allow WPF developers to build modern user interfaces that incorporate multimedia and are highly interactive. WPF is hardware accelerated, so applications have good performance.
WPF is a graphical subsystem that renders UI elements using DirectX. WPF extends the core .NET framework with a comprehensive set of features for building Windows client applications.
Some key characteristics of WPF are:
Vector Graphics: WPF uses vector graphics to render UI. This allows UIs to be resolution-independent and scale nicely on high DPI displays.
Hardware Acceleration: WPF uses modern graphics hardware for rendering, enabling smooth animations and transitions.
Declarative Syntax: UIs are defined in XAML, a declarative markup language. This enables the separation of UI definition from application logic.
Data Binding: WPF has rich data binding support to enable simple linkage between UI elements and data sources.
Templating: WPF has sophisticated theming and styling capabilities. Control templates enable customizing look and feel.
Multimedia Support: WPF includes multimedia, documents, and typography features for building rich presentation experiences.
Extensible: WPF provides various extensibility points to enable customization.
Overall, WPF provides a complete system for developing graphically rich Windows applications with engaging user experiences. The combination of vector graphics, hardware acceleration, and XAML make WPF a powerful UI platform.
Here are some of the major reasons to learn Windows Presentation Foundation:
In-Demand Skill: WPF skills are highly sought after by employers. Knowing WPF expands the range of desktop client application opportunities.
Modern UI Capabilities: WPF enables the creation of attractive, animated UIs incorporating multimedia. This allows for building modern, engaging applications.
XAML Productivity: Defining UIs declaratively using XAML is very productive. XAML simplify UI development and enables designer/developer workflows.

Rich Ecosystem: WPF has many supporting tools/libraries like Visual Studio, Blend, MahApps, and Caliburn.Micro that boosts productivity.
For any .NET developer looking to enhance their skillset, adding WPF will open opportunities in desktop application development and XAML-based UI frameworks. The capabilities and flexibility of WPF make it an essential UI technology.
WPF works very well in a range of scenarios, including:
Desktop Applications: Business applications, productivity tools, utilities, games, etc that target Windows users.
Data Visualization: WPF's 2D/3D graphics system allows building advanced data and mapping visualizations.
Media/Entertainment: With WPF's animation and media support, video players, design tools, and photo editors work well.
High-Performance UIs: Thanks to GPU acceleration, WPF excels at UIs with lots of rapidly updating elements.
Attractive UIs: To build an application with an attractive, modern, animated UI, WPF is a great choice.
MVVM Development: WPF's architecture and data binding fit nicely with Model-View-ViewModel, making it a good choice for enterprise applications.
Basically any Windows application where high graphical performance, visual appeal, animations, or a rich user experience are important can benefit from using WPF.
Some examples of popular applications built with WPF:
Microsoft Visual Studio
Microsoft Office 2016+
Adobe Illustrator

WPF provides a vast array of features for building desktop applications. Here are some of the major capabilities:
WPF uses vector graphics for rendering. This provides excellent support for scaling, zooming, rotations, and transforms without any loss of clarity. Vector graphics are resolution-independent.
WPF includes many pre-built controls like buttons, text boxes, list boxes, etc. Controls have rich templating capabilities to fully customize their visual appearance.
Binding UI elements to data sources is very simple. This reduces the code behind UIs. Bindings also enable automatic UI updates when data changes.
WPF includes a sophisticated layout system with Panel elements like Grid, StackPanel, DockPanel that enable many complex layout requirements.
Complete visual styling of controls is possible by customizing ControlTemplates. Styles, Triggers and Visual State Managers enable rich conditional styling.
WPF animations allow movement, fading, color changes and other transitions on UI elements. Timelines enable sequencing and coordinating animations.
Advanced graphics capabilities via DirectX integration allow stunning 2D and 3D visualizations and effects to be incorporated into applications.
Seamlessly integrate media like video, audio, and images into applications. WPF includes timeline controls for media playback.
Rich text, flow layout and pagination support via FlowDocument and FixedDocument for incorporating documents into applications.
Advanced typography with support for multiple fonts, international text, text decorations, text wrapping around shapes.
WPF provides various extensibility mechanisms like custom controls, user controls, data providers, dependency properties, markup extensions etc.
Here are some of the major benefits of using WPF for application development:
Declarative XAML Syntax - XAML is much more concise than procedural code for defining UIs and allows designer participation.
Hardware Accelerated Graphics - WPF applications have excellent performance thanks to GPU usage for rendering.
Resolution Independence - Vector graphics allow UIs to work well on high DPI monitors and resize smoothly.
Data Binding - Simple data binding reduces code behind UIs and glues UI and data together.
Templating - Complete control over the look and feel via templates and styling enables great custom UIs.
Animations - WPF animations allow building modern, slick UIs with motion and transitions.
Visually Engaging - Combination of graphics, media, and animation allows for building highly visual, multimedia-rich UIs.
Flexible Architecture - MVVM architecture and testability make WPF suitable for large LOB applications.
Extensible - Many extensibility points allow extensive customization of default WPF behavior.
Rich Ecosystem - Large community with many supporting frameworks, tools and third-party libraries.
WPF does have some downsides to balance out its advantages:
Windows Only - WPF works only on Windows, limiting cross-platform reach. Options exist to run WPF apps on Mac with limited support.
Steep Learning Curve - There are many parts to WPF - XAML, bindings, styles, templates, triggers, and animations. It takes time to master WPF.
Complexity - WPF is feature-rich but makes it more complex than simpler UI options—there are many choices to make.
Slower Release Cycle - WPF is legacy technology now. Innovation and new features come slowly. Progress is hindered.
Not Suited for All Apps - WPF may be overkill for simple CRUD forms over data applications. Simpler options may work fine.
Integration Challenges - Integrating modern web technologies like JavaScript, CSS frameworks can require additional work.
Limited Designer Support - Blend helps, but WPF designer experience not on par with designing HTML/CSS.
WPF provides a comprehensive and flexible platform for building Windows desktop applications with visually stunning user interfaces. The combination of XAML, hardware-accelerated graphics, animations, rich controls, data binding, styling, and extensibility mechanisms makes WPF extremely capable.
WPF skills are precious for developers looking to build modern line-of-business applications. The power and versatility of WPF make it relevant even now, many years since its first release. Learning WPF opens opportunities to work on desktop applications with dynamic UIs.
WinForms provides basic windowing UI functionality using GDI/GDI+ rendering. WPF is a much more advanced UI framework with capabilities like XAML, vector graphics, data binding, animations, etc.
WPF can only be used to build desktop client applications. However, integration with ASP.NET is possible on the server side. For web development, ASP.NET is more suitable.
No, WPF is a proprietary Microsoft technology closely coupled with Windows. But there are open-source implementations of WPF like Mono.
Microsoft is shifting focus to WinUI and UWP. However, WPF will remain supported, and incremental improvements will continue. Many existing code depends on WPF.
With third-party solutions like Mono, it is possible to run WPF applications on Mac and Linux with limited support. Performance may not be native.
XAML is very similar to WPF and UWP, with the biggest difference being UWP adding adaptive UI features like VisualStateManager.
