Empty WPF app crashes when published as a self-contained single file on .NET 11 Preview 7

[FIFER-Mods]

Description

A new empty WPF application targeting .NET 11 crashes on startup when published as a self-contained single-file application.

The failure occurs both with and without IncludeNativeLibrariesForSelfExtract=true. Ordinary non-single-file self-contained publishing works correctly.

This appears related to:

• Remove /clr:pure from WPF C++/CLI projects #11575
• [NETSDKE2E] With NET11.0.100-preview.5.26264.105 SDK installed, WPF application which is generated by self-contained publish cannot run successfully.  #11651
• Package ijwhost.dll as native asset for self-contained publish #11664

PR #11575 changed DirectWriteForwarder.dll and System.Printing.dll from pure MSIL to IJW mixed-mode assemblies. PR #11664 fixed ordinary self-contained publishing by packaging ijwhost.dll as a native runtime asset, but single-file publishing still bundles DirectWriteForwarder.dll and it fails during startup.

Reproduction Steps

Using .NET SDK 11.0.100-preview.7.26381.103:

dotnet new wpf -n WpfSingleFileRepro -f net11.0
cd WpfSingleFileRepro

dotnet publish -c Release -r win-x64 --self-contained true `
  -p:PublishSingleFile=true `
  -p:IncludeNativeLibrariesForSelfExtract=true `
  -o .\publish-single

.\publish-single\WpfSingleFileRepro.exe

Expected behavior

The empty WPF application should start and display its window.

Actual behavior

The process terminates during System.Windows.Application initialization with exit code 0xE0434352:

Unhandled exception. System.TypeInitializationException:
The type initializer for 'System.Windows.Application' threw an exception.

 ---> System.TypeInitializationException:
 The type initializer for '<Module>' threw an exception.

 ---> System.BadImageFormatException:
 File name: '...\publish-single\DirectWriteForwarder.dll'
