Hey @vibol03 this got closed wrongfully it seems, sorry about that. I’ve been digging into this a little and here is what I found.

If you remove <rescap:Capability Name="runFullTrust" /> and add only <DeviceCapability Name="location" /> (or any other for that matter, it will give the error that you described.

While looking at the docs here. I found this notice

This confirmed a hunch I was having… So I decided to not include <rescap:Capability Name="runFullTrust" />, but do include <DeviceCapability Name="location" /> and trigger a build that shows this error.

When I then look in bin\Debug\net7.0-windows10.0.19041.0\win10-x64 I see the generated AppxManifest.xml file and inside of that there is this:

  <Capabilities>
    <DeviceCapability Name="location" />
    <rescap:Capability Name="runFullTrust" />
  </Capabilities>

Going back to the note from the docs just above: this is invalid.

So it seems that somewhere the <rescap:Capability Name="runFullTrust" /> is added back. But I’m not sure if that is something we are doing or Win UI is doing. @mattleibow do you have any idea?

From a quick test it seems that this might be on Win UI, because when I update the dependency for Microsoft.WindowsAppSDK the generated manifest seems to not have this entry anymore, however another error is preventing me from actually running the app so I can’t say for sure.

On the main branch (.NET 8), we have already updated the dependency to the latest version so if you are willing and able you might try the .NET 8 preview else I think you’re stuck just adding the runFullTrust entry as well. If you do that and add the location one after it, that should work as expected.

Reopening for the time being while we verify these things.

I’m not sure why this bug was closed. I have provided the required feedback since last week. Can someone please advise? thanks
