Ok after some struggeling I’m able to pack a UWP app.
However I’m not able to install and test it. I’m in Developer mode and can’t install the App-Installer from store (button is greyed out) and powershell is telling me that there is no trust cert or something like that.
So i tried to install the certificate (How to create an app package signing certificate - Win32 apps | Microsoft Learn)
But this didn’t change anything. Now I’m stuck here. What do I need to do next to test the app?
And what is also important to know is what I’m actually doing. I’m just building a local test app now or is this app valid to upload to the store right after testing? I’m, still missing the overview of the entire progress.
