Tools for Universal Windows App Development

The Universal Windows App workload now includes a pre-release Creators Update SDK, build 15063, allowing you to start building apps for the Windows 10 Creators Update. These apps cannot be published to the Windows Store until the Creators Update has been released and you have rebuilt the apps using the final SDK and Tools for UWP. In addition, this release includes the following enhancements:

  • Starting with the Creators Update SDK, the Windows 10 SDK will install side-by-side. This allows you to use a single machine to build production-ready apps that target the released version of the SDK. You can begin testing new OS features delivered by a Preview Windows SDK.
  • NuGet package management has been improved by using PackageReference to replace package.config and package.json.
  • An enhanced .NET Native Compiler delivered as a NuGet package.
  • Improved tooling support for XAML controls delivered as NuGet packages.
  • IntelliSense in the XAML editor now highlights XAML types and properties that are not supported in the version of the SDK that your app is targeting.

For more information, see Creators Update SDK support in Visual Studio 2017.
