Building native custom action on ARM64 platform fails to find wix header files

Bugs

• Which version of WiX are you building with?

version 3.14.6526

• Which version of Visual Studio are you building with (if any)?

Visual Studio 2022 Community

• Which version of the WiX Toolset Visual Studio Extension are you building with (if any)?

1.0.0.22

• Which version of .NET are you building with?

.NET Framework 4.8.1

• Describe the problem and the steps to reproduce it.

Building a simple project (https://github.com/parvit/wix-vs2022-arm-bug) with a native custom action that uses includes files or links libraries from Wix Sdk folder (eg. wcautil), does not work when selecting ARM64 platform.

The same project and code builds correctly using the x64 platform.

• Describe the behavior you expected and how it differed from the actual behavior.

I've tracked the issue as being tied to the definitions in this file https://github.com/wixtoolset/wix3/blob/develop/src/tools/WixTasks/wix.nativeca.targets , that does not contain the 'VS2017' folder, which is the one that provides the files for the ARM64 platform.

In the project provided as example, if one uncomments the lines https://github.com/parvit/wix-vs2022-arm-bug/blob/fe30c7b7749abb47debdac55c54864e25d23e001/BasicCA/basic_ca.vcxproj#L194-L198 , the project builds as expected using VS2022 (or VS2022 build tools).

I hope i've been clear enough, I'm available for further clarifications if needed.

WiX v3 does not support VS2022. WiX v4 does.

@barnson Thank you for the fast response, however while i do understand that explicit support is targeted to the more recent v4, couldn't it be done to change the default in v3 at https://github.com/wixtoolset/wix3/blob/c5117b58502cace193732a6ba9204b68e2411355/src/tools/WixTasks/wix.nativeca.targets#L16 from VS2015 to VS2017?

That would only affect unsupported toolsets and allow for ARM support out of the box without adding workarounds in user code.

There are no plans to release another WiX v3 build.
