Windows 10 SDK preview build 17083 now available for developers

Just a week after the launch of the latest Windows Insider Preview build for Fast ring Insiders, Microsoft has released a new SDK Preview build to match. Developers can now get their hands on Windows 10 SDK Preview build 17083.

Like other recent SDK Preview releases, this one doesn't contain much in the way of changes, but there are some known issues to be aware of. The release notes also detail the same C++/WinRT compiler and MIDL keywords that were included in previous releases. Here's a look:

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:

Breaking Changes

  • New MIDL key words - As a part of the "modernizing IDL" effort, several new keywords are added to the midlrt tool. These new keywords will cause build breaks if they are encountered in IDL files. The new keywords are:
  • event
  • set
  • get
  • partial
  • unsealed
  • overridable
  • protected
  • importwinmd

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]

To work around this issue:

  • Go to Administrative Command Prompt
  • Run REGSVR32 "\Program Files (x86)\Windows Kits\10\bin\10.0.17083.0\x86\SirepClient.dll"
  • XAML Designer fails to load: To work around this issue, run a repair on the Windows SDK, or update you minimum target version of your app to be 10.0.17083.0.

For a full list of API updates and additions, you can check out Microsoft's release notes. This SDK preview build is only supported by Visual Studio 2017 and can be installed alongside previous SDKs. SDK Preview build 17083 can be downloaded from Microsoft now.
