Windows 10: Windows 10 SDK Preview Build 18917 available now - June 18

Brink · Jun 18, 2019

Today, we released a new Windows 10 Preview Build of the SDK to be used in conjunction with Windows 10 Insider Preview (Build 18917 or greater). The Preview SDK Build 18917 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 and 2019. You can install this SDK and still also continue to submit your apps that target Windows 10 build 1903 or earlier to the Microsoft Store.

The Windows SDK will now formally only be supported by Visual Studio 2017 and greater. You can download the Visual Studio 2019 here.

This build of the Windows SDK will install ONLY on Windows 10 Insider Preview builds.

In order to assist with script access to the SDK, the ISO will also be able to be accessed through the following static URL: https://software-download.microsoft.com/download/sg/Windows_InsiderPreview_SDK_en-us_18917_1.iso.

Tools Updates

Message Compiler (mc.exe)

Now detects the Unicode byte order mark (BOM) in .mc files. If the If the .mc file starts with a UTF-8 BOM, it will be read as a UTF-8 file. Otherwise, if it starts with a UTF-16LE BOM, it will be read as a UTF-16LE file. If the -u parameter was specified, it will be read as a UTF-16LE file. Otherwise, it will be read using the current code page (CP_ACP).

Now avoids one-definition-rule (ODR) problems in MC-generated C/C++ ETW helpers caused by conflicting configuration macros (e.g. when two .cpp files with conflicting definitions of MCGEN_EVENTWRITETRANSFER are linked into the same binary, the MC-generated ETW helpers will now respect the definition of MCGEN_EVENTWRITETRANSFER in each .cpp file instead of arbitrarily picking one or the other).

Windows Trace Preprocessor (tracewpp.exe)

Now supports Unicode input (.ini, .tpl, and source code) files. Input files starting with a UTF-8 or UTF-16 byte order mark (BOM) will be read as Unicode. Input files that do not start with a BOM will be read using the current code page (CP_ACP). For backwards-compatibility, if the -UnicodeIgnore command-line parameter is specified, files starting with a UTF-16 BOM will be treated as empty.

Now supports Unicode output (.tmh) files. By default, output files will be encoded using the current code page (CP_ACP). Use command-line parameters -cp:UTF-8 or -cp:UTF-16 to generate Unicode output files.

Behavior change: tracewpp now converts all input text to Unicode, performs processing in Unicode, and converts output text to the specified output encoding. Earlier versions of tracewpp avoided Unicode conversions and performed text processing assuming a single-byte character set. This may lead to behavior changes in cases where the input files do not conform to the current code page. In cases where this is a problem, consider converting the input files to UTF-8 (with BOM) and/or using the -cp:UTF-8 command-line parameter to avoid encoding ambiguity.

TraceLoggingProvider.h

Now avoids one-definition-rule (ODR) problems caused by conflicting configuration macros (e.g. when two .cpp files with conflicting definitions of TLG_EVENT_WRITE_TRANSFER are linked into the same binary, the TraceLoggingProvider.h helpers will now respect the definition of TLG_EVENT_WRITE_TRANSFER in each .cpp file instead of arbitrarily picking one or the other).

In C++ code, the TraceLoggingWrite macro has been updated to enable better code sharing between similar events using variadic templates.

Breaking Changes

Removal of IRPROPS.LIB

In this release irprops.lib has been removed from the Windows SDK. Apps that were linking against irprops.lib can switch to bthprops.lib as a drop-in replacement.

API Updates, Additions and Removals

The following APIs have been added to the platform since the release of Windows 10 SDK, version 1903, build 18362.

Windows 10 SDK Preview Build 17035 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 17035 or greater). The Preview SDK Build 17035 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.

Known Issues:

Installation on an operating system that is not a Windows 10 Insider Preview build is not supported and may fail.

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: microsoft/cppwinrt.

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

If any of these keywords are used as an identifier, it will generate a build failure indicating a syntax error.

The error will be similar to:

1 >d:\os\src\onecore\com\combase\unittest\astatestservers\testserver6\idl\remreleasetest.idl(12) : error MIDL2025 : [msg]syntax error [context]: expecting a declarator or * near “)”

To fix this, modify the identifier in error to an “@” prefix in front of the identifier. That will cause MIDL to treat the offending element as an identifier instead of a keyword.

Windows 10 SDK Preview Build 18298 available now - Dec. 18

Today, we released a new Windows 10 Preview Build of the SDK to be used in conjunction with Windows 10 Insider Preview (Build 18298 or greater). The Preview SDK Build 18298 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 build 1809 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 ONLY on Windows 10 Insider Preview builds.

In order to assist with script access to the SDK, the ISO will also be able to be accessed through the following URL: https://go.microsoft.com/fwlink/?prd...dsurl&o1=18298 once the static URL is published.

Tools Updates

Message Compiler (mc.exe)

The “-mof” switch (to generate XP-compatible ETW helpers) is considered to be deprecated and will be removed in a future version of mc.exe. Removing this switch will cause the generated ETW helpers to expect Vista or later.

The “-A” switch (to generate .BIN files using ANSI encoding instead of Unicode) is considered to be deprecated and will be removed in a future version of mc.exe. Removing this switch will cause the generated .BIN files to use Unicode string encoding.

The behavior of the “-A” switch has changed. Prior to Windows 1607 Anniversary Update SDK, when using the -A switch, BIN files were encoded using the build system’s ANSI code page. In the Windows 1607 Anniversary Update SDK, mc.exe’s behavior was inadvertently changed to encode BIN files using the build system’s OEM code page. In the 19H1 SDK, mc.exe’s previous behavior has been restored and it now encodes BIN files using the build system’s ANSI code page. Note that the -A switch is deprecated, as ANSI-encoded BIN files do not provide a consistent user experience in multi-lingual systems.

Breaking Changes

Change to effect graph of the AcrylicBrush

In this Preview SDK, we’ll be adding a blend mode to the effect graph of the AcrylicBrush called Luminosity. This blend mode will ensure that shadows do not appear behind acrylic surfaces without a cutout. We will also be exposing a LuminosityBlendOpacity API available for tweaking that allows for more AcrylicBrush customization.

By default, for those that have not specified any LuminosityBlendOpacity on their AcrylicBrushes, we have implemented some logic to ensure that the Acrylic will look as similar as it can to current 1809 acrylics. Please note that we will be updating our default brushes to account for this recipe change.

TraceLoggingProvider.h / TraceLoggingWrite

Events generated by TraceLoggingProvider.h (e.g. via TraceLoggingWrite macros) will now always have Id and Version set to 0.

Previously, TraceLoggingProvider.h would assign IDs to events at link time. These IDs were unique within a DLL or EXE, but changed from build to build and from module to module.
