`WinUI` unknown exception when running as `Project` instead of `MsixPackage`

[AndreasReitberger]

Description

I'm facing a problem while trying to release my app as Project on Windows. When I start the application set as Project in the LaunchSettings

{
  "profiles": {
    "Windows Machine": {
      //"commandName": "MsixPackage",
      "commandName": "Project",
      "nativeDebugging": false
    }
  }
}

<WindowsPackageType Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">None</WindowsPackageType>

<!-- set false to build an exe file instead -->
<GenerateAppxPackageOnBuild>false</GenerateAppxPackageOnBuild>

I get an Microsoft.UI.Xaml.UnhandledException exception.

Value does not fall within the expected range.

Stacktrace:

When I switch back to MsixPackage, the app works. Same applies for Android. Only WinUI as unpackaged built gives me this exception.

{
  "profiles": {
    "Windows Machine": {
      "commandName": "MsixPackage",
      //"commandName": "Project",
      "nativeDebugging": false
    }
  }
}

		<GenerateAppxPackageOnBuild>true</GenerateAppxPackageOnBuild>
		<AppxBundle>Always</AppxBundle>
		<AppxBundlePlatforms>x86|x64|arm</AppxBundlePlatforms>

I'm actually kinda lost how to debug the root-cause with this exception. The only which popsup on the working configuration is this Binding issue, which I cannot identify in my project source code.

Schweregrad Anzahl Datenkontext Bindungspfad Ziel Zieltyp Beschreibung Datei Zeile Projekt Fehler 1 Microsoft.UI.Xaml.Controls.SplitView TemplateSettings.CompactPaneGridLength Microsoft.UI.Xaml.Media.Animation.SplineDoubleKeyFrame.Value Double Converter failed to convert value of type 'Windows.Foundation.IReference`1<Microsoft.UI.Xaml.GridLength>' to type 'Double'

Maybe this is the reason why the Project build fails...

I nailed it down to setting the FontFamily for the SfBusyControl. If I remove the setter, it works. Seems to be an issue to find the font again, if released unpackaged.

Repro: https://github.com/AndreasReitberger/SfBusyIndicatorMauiIssue Reported also to syncfusion: https://support.syncfusion.com/support/tickets/579453

Edit: Seems to be relevant to each syncfusion control if setting the FontFamily and publish unpackaged

Verified this issue with Visual Studio 17.10.0 Preview 3 (8.0.20 & 8.0.14).I can not repro this issue on windows machine.

Are you able to publish the example as executable without a crash? It does not work on my end.

I'm on Win11 if that matters.

Syncfusion has verified this issue and found the root cause at CanvasTextFormat
