Errors while converting from wix3.14 to wix 4

[RAppels2022]

While converting from 3.14 to wix 4 in VS2019, all the include files have disappeared but the errors come from those include files.

What can I do to fix this, or do I have to wait on the next preview version?

This looks like a HeatWave conversion issue. Would you mind opening an issue over at HeatWave Support with details about how your .wxi files were listed in your .wixproj? I expect that information will be relevant for the FireGiant team to investigate.

You don't have to wait for the next preview version. You should be able to run wix.exe convert on the .wxi files manually.
