Publishing to the Microsoft Store?

[plettb]

I am having all kinds of trouble publishing my Maui app to the Microsoft Store.

1. If I try publishing from Visual Studio, I get the following error:

• "You must publish one version of this application to the Microsoft Store before using the Store submission automation tool"

2. If I try to upload the package manually to the Microsoft Store (i.e. in a package submission), I get the following errors:

• "Invalid package family name: XXXXXXXX.XXXXXXXXXXXXX_6k51yetae26ce (expected: XXXXXXXX.XXXXXXXXXXXXX_t7g5vnbs3ke9w)" - but I have no control over the suffix that gets added. Where/how do I change that?
• "Declared package dependency unavailable: Microsoft.WindowsAppRuntime.1.2, Neutral, Universal,Universal" - how do I fix this? Can I include it as a dependency somehow?

Thanks!

Hi @VladislavAntonyuk
I have tried using your approach and saw one of your comments regarding using dotnet publish instead now.

I can successfully create a MSIX with by either using dotnet publish or through the right-click on .csproj, then click publish method.
However, this does not seem to pick up the Identity from Package.appxmanifest, instead, it uses an Identity from a local certificate on the machine. Logically, when I then upload it to partner center, the Identity does not match so the partner center does not allow me to continue.
If I delete the certificate that was used on my machine, the publish command actually fails.
Do I need to buy or create a certificate, that matches the Id in the partner center? I thought, the whole point of the VS/MS Store publish is, that I don't actually need that?!

I feel like, I must be getting something wrong and was wondering, if you could point me in the right direction..

Hello, @borrmann
No, you don't need to buy certificates if you publish to Microsoft Store.
You can find my pipeline at VladislavAntonyuk/WorldExplorer. It produces the final msix file that is ready for Microsoft store.
