Copy font assets only works at second build

[AlleSchonWeg]

Description

I wondered, why me IconFont was not working in release mode. The font is in Resources\Fonts\ folder referenced in .csproj:

  <!-- Custom Fonts -->
  <MauiFont Include="Resources\Fonts\*" />

I builded the app and deployed it to the simulator but no icon was shown. Hmm, in debug mode it works. So i looked in the obj folder. In Debug\net8.0-android\assets my ttf file was shown. In Release\net8.0-android\assets was no ttf file:

I started deleting obj/bin folders and rebuild. On the first build the assets folder keeps empty but with the second build the folder contains the ttf files and my icon font starts working in release mode:

The screenshots shows the default MAUI App with the included fonts. The behavior is the same.

Steps to Reproduce

1. Create App from VS template
2. Delete obj/bin folders
3. Build Release and look at the assets folder --> folder emty
4. Build again. Folder not empty

The same/similar happens in Debug config. I think the users don't notice this because in debug mode the app is usually already installed and the font files are already stored on the device. Or the user rebuild the app multiple times and then the assets are there.

Edit: Perhaps this doesn't happen only with font assets.

I can repro this issue on the latest 17.11.0 Preview 2.1 (8.0.60 & 8.0.40)

I provided a similar issue/bug report on this months ago...

If you delete the "obj/bin" folders, and compile/deploy the application (debug OR release), it will ALWAYS leave some of your "resources" behind. Sometimes it is a font file, or two... Most of the time, it is the images... And rarely, a file from the "Assets" folder.

You have to compile, deploy, the compile again for it to "collect" all of your resources. It NEVER works on the first try after removing the "obj/bin" folders!

This happens on Android, and Windows...

@Stedy59 would you happen to have the issue number for that?

I looked and could not find the issue reported. I do remember commenting, such as I did here, on this issue months ago.

The multiple compile/deploy regiment is required if you remove the "obj/bin" folders.

Also, on a side note... Since all of my "controls (15) / core" are in libraries, sometimes changes WILL NOT be included in subsequent builds unless I remove the "obj/bin" folders... I author custom code libraries for Zebra/Honeywell/Data Logic devices (Barcode scanners / RFID / etc.)
