I am building a windows brdige app, and trying to include adaptive scaling assets for the tiles and such. However, when building the package, makeappx complains about non-existing files.
I use the following appxmanifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<!--suppress XmlUnusedNamespaceDeclaration -->
<Package

However, on running makeappx, i get the following errors:
MakeAppx : error: Manifest validation error: Line 33, Column 8, Reason: The file name "assets\Square150x150Logo.png" declared for element "*[local-name()='Applications']/*[local-name()='Application']/*[local-name()='VisualElements']" doesn't exist in the package.

However, the assets directory does contain the files needed with the naming scheme as described in https://learn.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/app-assets:

What am I missing/doing wrong?
I was having similar problems with the adaptive assets. I am using electron-windows-store to package my app, but it was also complaining about non-existent files. Turns out there is a makepri.exe program that can run before makeappx.exe and it prepares the assets for makeappx.exe.
I don't know exactly how this works when running the programs manually, but when using electron-windows-store setting makePri: true in the config allows me to use the adaptive resolution assets. In my case the makepri.exe program was downloaded along with the windows SDK, same folder as makeappx.exe.
Unfortunately I couldn't find any good documentation on how these programs work outside of Visual Studio.
