Distributing WinUI app... in MS Store

[blmiles]

Hello,

Seeking any guidance here. My maui app targets Android, iOS and I've now added WinUI 3.
These ALL work in Release mode and both the Android and iOS version work after installing from the respective stores.

Uploading a package into the MS Store states this:
Drag your packages here (.msix, .msixbundle, .msixupload, .appx, .appxbundle, .appxupload, .xap)

My environment does not seem to want to build the .msix package, and yes, this is set:
<WindowsPackageType>MSIX</WindowsPackageType> in the .csproj file.
I'm sure I'm missing settings and/or steps after building in Release.

Any advice on what is best to use to upload to the MS Store?

Thanks

You can't just build in Release to generate the MSIX file, you will need to run the dotnet publish command. The method of using this is detailed at https://learn.microsoft.com/en-gb/dotnet/maui/windows/deployment/publish-cli?view=net-maui-9.0
