Microsoft today released the Windows 10 SDK Preview build 17061. This release is meant to be used with the consumer-facing Windows 10 Insider Preview build 17061 or greater and includes bug fixes and under development changes to the API surface area. The download is now available developer section of the Windows Insider website, and here is a look at the known issues and what’s new.

Known Issues:

  • Installation on an operating system that is not a Windows 10 Insider Preview build is not supported and may fail.
  • Cannot deploy to a device: When attempting to deploy to a mobile device, it fails with the following error: DEP0001: Unexpected Error: SmartDeviceException – Class not registered [0x80131500]
  • Please follow this posting for updates.
  • XAML Designer fails to load: When attempting to load the XAML designer, an Unhandled exception occurs “The XAML Designer has excited unexpectedly.

What’s New:

  • C++/WinRT Now Available: The C++/WinRT headers and cppwinrt compiler (cppwinrt.exe) are now included in the Windows SDK. The compiler comes in handy if you need to consume a third-party WinRT component or if you need to author your own WinRT components with C++/WinRT. The easiest way to get working with it after installing the Windows Insider Preview SDK is to start the Visual Studio Developer Command Prompt and run the compiler in that environment. Authoring support is currently experimental and subject to change. Stay tuned as we will publish more detailed instructions on how to use the compiler in the coming week.The ModernCPP blog has a deeper dive into the CppWinRT compiler. Please give us feedback by creating an issue at: https://github.com/microsoft/cppwinrt.

There are a set of API Updates and Additions which should be taken note of, and these are available here. Additionally, there are breaking Changes, which include New MIDL keywords, as explained in past SDK Preview build posts. Please keep in mind that this build works in conjunction with previously released SDKs and Visual Studio 2017 and is only supported in Visual Studio 2017 and greater.
