Publish as MSIX bundle or APPX bundle for Windows

[BrandonStudio]

Description

Visual Studio can now only publish single target msix, but I'd like to create multi-targeting app (both x64 and ARM64 or more) all in once. It seems there is no way to do this

Public API Changes

It's a problem of build tools, there's nothings to do with API

Intended Use-Case

Same as above

Depends on

It appears the Windows App SDK does not support building a msixbundle from dotnet.

@evelynwu-msft do we have anymore info?

Been hacking away at this and I think I got something that will make this all work wonderfully:

If we get some testing on this we may be able to include somewhere until the WASDK issue is resolved.

@mattleibow is it for build only? Is it for CLI only? Can I publish my project as bundle in Visual Studio?

[mattleibow]

I do not believe there is a way to publish using this from the IDE, but the CLI will work.

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

@mattleibow how can I use your workaround to generate a '.msixupload' file to be able upload to the Microsoft Store? We're getting ready to release and I feel like I'm about to tell management that after all our work to start on this endeavor we won't be able to release. Here is what I'm currently using based off of the original Xamarin.Forms app that we moved to MAUI:

>dotnet.exe publish MyApp.csproj --framework net8.0-windows10.0.22621.0 --configuration Release --self-contained -nologo -nr:false -nologo -nr:false -p:AppxBundle=Always;UapAppxPackageBuildMode=StoreUpload;AppxBundlePlatforms="x86|x64"; /t:GenerateMsixBundle

When will this be resolved? - given how long it's been and that MAUI has been available for a while it seems silly to think I can't just run dotnet publish and generate a bundle targeting multiple architectures for upload to the Microsoft Store (like I can for iOS and Android). The documentation and samples provide no reasonable effort to showcase how to workaround the limitations of MSIX and Windows App SDK.

This is an urgent issue that should have been addressed as part of the .NET 9 release!

Thanks @mattleibow your work-around produces a msixbundle file for my Maui app that successfully updates an appxbundle of my Xamarin app. (before the work-around I was getting error 0x80073cf3).

Agreed!
