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's rendering is vector-based, which 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.

Visual Studio's designer, as well as Visual Studio Blend, make it easy to build WPF applications, with drag-and-drop and/or direct editing of XAML markup.

As of .NET 6.0, WPF supports ARM64. 

See the [WPF Roadmap](roadmap.md) to learn about project priorities, status and ship dates.

[WinForms](https://github.com/dotnet/winforms) is another UI framework for building Windows desktop applications that is supported on .NET (7.0.x/6.0.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](https://visualstudio.microsoft.com/downloads/) to develop WPF and WinForms applications for .NET.  

To build the WPF repo and contribute features and fixes for .NET 8.0, [Visual Studio 2022 Preview](https://visualstudio.microsoft.com/vs/preview/) is required.

## Getting started

* [.NET 6.0 SDK](https://dotnet.microsoft.com/download/dotnet/6.0), [.NET 7.0 SDK](https://dotnet.microsoft.com/download/dotnet/7.0), [.NET 8.0 SDK](https://dotnet.microsoft.com/download/dotnet/8.0), [.NET 9.0 SDK](https://dotnet.microsoft.com/download/dotnet/9.0)
* [.NET Preview SDKs](https://github.com/dotnet/dotnet/blob/main/docs/builds-table.md)
* [Getting started instructions](Documentation/getting-started.md)
* [Contributing guide](Documentation/contributing.md)
* [Migrating .NET Framework WPF Apps to .NET Core](https://learn.microsoft.com/en-us/dotnet/desktop/wpf/migration/)

## Status

- We are currently developing WPF for .NET 10. 

See the [WPF roadmap](roadmap.md) to learn about the schedule for specific WPF components.

Test published at [separate repo](https://github.com/dotnet/wpf-test) 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. 

## How to Engage, Contribute and Provide Feedback

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](Documentation/contributing.md) and also follows the more general [.NET Core contributing guide](https://github.com/dotnet/runtime/blob/main/CONTRIBUTING.md).
* If you have a question or have found a bug, [file an issue](https://github.com/dotnet/wpf/issues/new).
* Use [daily builds](Documentation/getting-started.md#installation) if you want to contribute and stay up to date with the team.

### .NET Framework issues

Issues with .NET Framework, including WPF, should be filed on [VS developer community](https://developercommunity.visualstudio.com/spaces/61/index.html), 
or [Product Support](https://support.microsoft.com/en-us/contactus?ws=support).
They should not be filed on this repo.

## Relationship to .NET Framework

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](https://devblogs.microsoft.com/dotnet/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](https://devblogs.microsoft.com/dotnet/net-core-is-the-future-of-net/) 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.
