System requirements for Windows app development
To develop apps for Windows 11 and Windows 10, you'll need Visual Studio, the Windows SDK, and the Windows App SDK. Before installing these tools, check the information in this article to make sure your development computer meets the minimum system requirements.
For instructions to install and set up these tools, see Install tools for the Windows App SDK.
Visual Studio is a comprehensive integrated development environment (IDE) that you can use to edit, debug, and build code, and then publish your app.
For the minimum system requirements, see:
The Windows SDK provides access to all the APIs and development features exposed by the Windows OS. The Windows SDK is required for building Windows apps as well as other types of components such as services and drivers. The latest Windows SDK is installed with Visual Studio 2019 and Visual Studio 2022 by default.
For the minimum system requirements, see Windows SDK system requirements.
Windows App SDK
The Windows App SDK is a set of developer tools that represent the next evolution in the Windows app development platform. The Windows App SDK provides a unified set of APIs and tools that can be used in a consistent way by any desktop app on Windows 11 and downlevel to Windows 10, version 1809.
The Windows App SDK was previously known by the code name Project Reunion. Some SDK assets such as the VSIX extension and NuGet packages still use the code name, but these assets will be renamed in a future release. Some areas of the documentation still use Project Reunion when referring to an existing asset or a specified earlier release.
The Windows App SDK has these system requirements:
Windows 10, version 1809 (build 17763) or later.
Visual Studio 2019 version 16.9 or later with the required components. For more information, see Required workloads and components
Windows SDK version 2004 (build 19041) or later, as included with Visual Studio 2019 and Visual Studio 2022 by default.
Building .NET apps also requires .NET 6 or later (see Download .NET.
Visual Studio support for WinUI 3 tools
You can build, run, and deploy apps built with stable versions of the Windows App SDK on Visual Studio 2019 versions 16.9, 16.10, and 16.11 Preview. You can also use Visual Studio 2022 17.0 Preview 2 and later to build apps with the Windows App SDK v0.8.2 and later. However, in order to take advantage of the latest WinUI 3 tooling features such as Hot Reload, Live Visual Tree, and Live Property Explorer, you need the versions of Visual Studio 2019 with the stable versions of the Windows App SDK as listed in the following table.
