Fix resource.pri handling in single file publishing for WindowsAppSDK

[Copilot]

Issue

When creating a single executable from an unpackaged app with PublishSingleFile=true and WindowsAppSDKSelfContained=true, the latest Windows App SDK (1.5.240428000) fails to properly include the resource.pri file in the output. This causes runtime errors when attempting to load resources from the app.

Root Cause

In version 1.5 of Windows App SDK, resource files (including resource.pri) are supposed to be embedded into the executable and extracted to a temporary directory at runtime. However, the required MSBuild properties to ensure this extraction works correctly were not being set when both PublishSingleFile and WindowsAppSDKSelfContained were enabled.

Solution

Added the following properties to Microsoft.WindowsAppSDK.Foundation.targets to ensure resource files are properly included for self-extraction during single file publishing:

<!-- Ensure resource.pri and other necessary files are properly included in single file publishing -->
<PropertyGroup Condition="'$(PublishSingleFile)' == 'true' and '$(WindowsAppSDKSelfContained)' == 'true'">
  <IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
  <IncludeAllContentForSelfExtract>true</IncludeAllContentForSelfExtract>
</PropertyGroup>

These properties ensure that:

• IncludeNativeLibrariesForSelfExtract - Native libraries (including MRM.dll which handles resources) are included for self-extraction
• IncludeAllContentForSelfExtract - All content files (including resource.pri) are included for self-extraction

This fix allows resource files to be properly extracted at runtime from the single file executable, restoring the functionality that was working in Windows App SDK 1.4.

Fixes #9.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.fwupd.org
  • Triggering command: /usr/bin/fwupdmgr refresh (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
