Windows Presentation Foundation (WPF) is a UI framework for building Windows desktop applications. WPF supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding and documents. WPF uses the Extensible Application Markup Language (XAML) to provide a declarative model for application programming.

WPF applications are based on a vector graphics architecture. This enables applications to look great on high DPI monitors, as they can be infinitely scaled. WPF also includes a flexible hosting model, which makes it straightforward to host a video in a button, for example. The visual designer provided in Visual Studio makes it easy to build WPF application, with drag-in-drop and/or direct editing of XAML markup.

See the WPF Roadmap to learn about project priorities, status and ship dates.

WinForms is another UI framework for building Windows desktop applications that is supported on .NET (6.0.x/5.0.x/3.1.x). WPF and WinForms applications only run on Windows. They are part of the Microsoft.NET.Sdk.WindowsDesktop SDK. You are recommended to use the most recent version of Visual Studio to develop WPF and WinForms applications for .NET.

WPF for ARM64 is new for .NET 6.0 and is supported by NET 6.0 Preview 1 and later.

To build the WPF repo and contribute features and fixes for .NET 6.0, the most recent Visual Studio Preview is required.

• .NET 5.0 SDK
• .NET Preview SDKs (6.0 Preview 1, 5.0 servicing, and 3.1 servicing)
• Getting started instructions
• Contributing guide
• Migrating .NET Framework WPF Apps to .NET Core

• We are currently developing WPF for .NET 6.
• We have completed publishing WPF sources. You can learn more about this at dotnet#2554.
• We have completed porting WPF to .NET Core as part of .NET Core 3.0, you can learn more about what was done here.

See the WPF roadmap to learn about the schedule for specific WPF components.

Test published at separate repo Tests and have limited coverage at this time. We will add more tests, however, it will be a progressive process.

The Visual Studio WPF designer is now available as part of Visual Studio 2019.

Some of the best ways to contribute are to try things out, file bugs, join in design conversations, and fix issues.

• This repo defines contributing guidelines and also follows the more general .NET Core contributing guide.
• If you have a question or have found a bug, file an issue.
• Use daily builds if you want to contribute and stay up to date with the team.

Issues with .NET Framework, including WPF, should be filed on VS developer community, or Product Support. They should not be filed on this repo.

This code base is a fork of the WPF code in the .NET Framework. .NET Core 3.0 was released with a goal of WPF having parity with the .NET Framework version. Over time, the two implementations may diverge.

The Update on .NET Core 3.0 and .NET Framework 4.8 provides a good description of the forward-looking differences between .NET Core and .NET Framework.

This update states how going forward .NET Core is the future of .NET. and .NET Framework 4.8 will be the last major version of .NET Framework.
