How to pass publisher bridging parameter to makeappx with packaging project?

[Marv51]

Unfortunately our new code signing certificate has some changes compared to our old one. So to keep the same identity I am following this help page on: MSIX persistent identity .

The page manually calls makeappx with a /pb or /publisherBridging parameter.

Now I am using WinAppSDK and WinUI 3 so my packaging is done with the packaging project (.wapproj).

Can I pass an msbuild parameter to set that makeappx parameter somehow?
If not, do you have any instructions available how to manually create an msixbundle from my WinAppSDK/WinUI 3 project?

I'm having the same problem... it doesn't help that there's absolutely no documentation on the various appx parameters for msbuild :-\

@Marv51 did you end up trying the publisherBridging arg with msbuild?

[Marv51]

Publisher Bridge does not work for our requirements, as it only works on Windows 11.

That is among many issues the deal breaker for us.

I filed/documented some more issues here: MicrosoftDocs/msix-docs#326

A solution was posted here - cross-referencing it here so it's easier to find: MicrosoftDocs/msix-docs#326 (comment)
