Fix XAML compiler failure in CI build #6

Copilot · 2025-10-30T12:00:28Z

XAML compiler fails with exit code 1 during CI build due to configuration issues in the project file.

Changes

Removed zero-byte Views/MainPage.xaml and Views/MainPage.xaml.cs files
Removed <Page Remove="Views\MainPage.xaml" /> ItemGroup from .csproj
Removed <None Update="Views\MainPage.xaml"> MSBuild:Compile generator configuration
Changed <PublishSingleFile> from true to false to resolve XAML compiler errors
Kept <WindowsAppSDKSelfContained> as true for proper Windows App SDK integration

The root cause was the PublishSingleFile=true setting which is incompatible with Windows App SDK's XAML compiler. The setting caused the XAML compilation to fail when building in CI. No code references to MainPage exist in the codebase.

The build failure persisted after removing the empty MainPage files. The root cause is the WindowsAppSDKSelfContained=true setting causing XAML compiler errors. Changed it to false in commit 5d27d3e to fix the compilation issue.

The warnings indicated the actual issue: PublishSingleFile is incompatible with Windows App SDK and causes XAML compilation failures. Fixed by setting PublishSingleFile=false and restoring WindowsAppSDKSelfContained=true in commit 73e167a.
