Windows Forms

License: MIT

Windows Forms (WinForms) is a UI framework for building Windows desktop applications. It is a .NET wrapper over Windows user interface libraries, such as User32 and GDI+. It also offers controls and other functionality that is unique to Windows Forms.

Windows Forms also provides one of the most productive ways to create desktop applications based on the visual designer provided in Visual Studio. It enables drag-and-drop of visual controls and other similar functionality that make it easy to build desktop applications.

Windows Forms Designer

For more information about the designer, please see the Windows Forms Designer Documentation.

To learn about project priorities as well as status and ship dates see the Windows Forms Roadmap.

⚠️ This repository contains WinForms for .NET Core. It does not contain the .NET Framework variant of WinForms.

Windows Presentation Foundation (WPF) is another UI framework used to build Windows desktop applications which is supported on .NET Core. WPF and Windows Forms applications run only on Windows operating systems. They are part of the Microsoft.NET.Sdk.WindowsDesktop SDK. You are recommended to use Visual Studio 2019 Preview 1 to use WPF and Windows Forms with .NET Core.

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.

.NET Framework issues

Issues with .NET Framework, including Windows Forms, should be filed on the Developer Community or Product Support websites. They should not be filed on this repository.

Reporting security issues

Security issues and bugs should be reported privately via email to the Microsoft Security Response Center (MSRC) secure@microsoft.com. You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Further information, including the MSRC PGP key, can be found in the Security TechCenter. Also see info about related Microsoft .NET Core and ASP.NET Core Bug Bounty Program.

Relationship to .NET Framework

This codebase is a fork of the Windows Forms code in the .NET Framework 4.8. In Windows Forms .NET Core 3.0, we've strived to bring the two runtimes to a parity. However, since then, we've done a number of changes, including breaking changes, which diverged the two.

For more information about breaking changes, see the Porting guide.
