Windows 10 SDK Preview Build 17661 now available!

Windows 10 SDK Preview Build 17661 now available!

Today, we released a new Windows 10 Preview Build of the SDK to be used in conjunction with Windows 10 Insider Preview (Build 17661 or greater). The Preview SDK Build 17661 contains bug fixes and under development changes to the API surface area.

The Preview SDK can be downloaded from developer section on Windows Insider.

For feedback and updates to the known issues, please see the developer forum. For new developer feature requests, head over to our Windows Platform UserVoice.

Things to note:

• This build works in conjunction with previously released SDKs and Visual Studio 2017. You can install this SDK and still also continue to submit your apps that target Windows 10 Creators build or earlier to the store.
• The Windows SDK will now formally only be supported by Visual Studio 2017 and greater. You can download the Visual Studio 2017 here.
• This build of the Windows SDK will install on Windows 10 Insider Preview and supported Windows operating systems.

Known Issues

The contract Windows.System.SystemManagementContract is not included in this release. In order to access the following APIs, please use a previous Windows IoT extension SDK with your project.

This bug will be fixed in a future preview build of the SDK.

The following APIs are affected by this bug:

namespace Windows.Services.Cortana {
  public sealed class CortanaSettings     
}
namespace Windows.System {
  public enum AutoUpdateTimeZoneStatus
  public static class DateTimeSettings
  public enum PowerState
  public static class ProcessLauncher
  public sealed class ProcessLauncherOptions
  public sealed class ProcessLauncherResult
  public enum ShutdownKind
  public static class ShutdownManager
  public struct SystemManagementContract
  public static class TimeZoneSettings
}

What’s New:

MC.EXE

We’ve made some important changes to the C/C++ ETW code generation of mc.exe (Message Compiler):

The “-mof” parameter is deprecated. This parameter instructs MC.exe to generate ETW code that is compatible with Windows XP and earlier. Support for the “-mof” parameter will be removed in a future version of mc.exe.

As long as the “-mof” parameter is not used, the generated C/C++ header is now compatible with both kernel-mode and user-mode, regardless of whether “-km” or “-um” was specified on the command line. The header will use the _ETW_KM_ macro to automatically determine whether it is being compiled for kernel-mode or user-mode and will call the appropriate ETW APIs for each mode.

• The only remaining difference between “-km” and “-um” is that the EventWrite[EventName] macros generated with “-km” have an Activity ID parameter while the EventWrite[EventName] macros generated with “-um” do not have an Activity ID parameter.

The EventWrite[EventName] macros now default to calling EventWriteTransfer (user mode) or EtwWriteTransfer (kernel mode). Previously, the EventWrite[EventName] macros defaulted to calling EventWrite (user mode) or EtwWrite (kernel mode).

• The generated header now supports several customization macros. For example, you can set the MCGEN_EVENTWRITETRANSFER macro if you need the generated macros to call something other than EventWriteTransfer.
• The manifest supports new attributes.
  • Event “name”: non-localized event name.
  • Event “attributes”: additional key-value metadata for an event such as filename, line number, component name, function name.
  • Event “tags”: 28-bit value with user-defined semantics (per-event).
  • Field “tags”: 28-bit value with user-defined semantics (per-field – can be applied to “data” or “struct” elements).
• You can now define “provider traits” in the manifest (e.g. provider group). If provider traits are used in the manifest, the EventRegister[ProviderName] macro will automatically register them.
• MC will now report an error if a localized message file is missing a string. (Previously MC would silently generate a corrupt message resource.)
• MC can now generate Unicode (utf-8 or utf-16) output with the “-cp utf-8” or “-cp utf-16” parameters.

API Updates and Additions

When targeting new APIs, consider writing your app to be adaptive in order to run correctly on the widest number of Windows 10 devices. Please see Dynamically detecting features with API contracts (10 by 10) for more information.

The following APIs have been added to the platform since the release of 17134.
