  I have a desktop .NET application that targets both .NET 8 and .NET 9, developed with Visual Studio 2022.

  I am using the latest version of C1.Win.Printing.dll (10.0.20261.779).

  I have encountered an issue with MultiDocument when targeting .NET 9. Specifically, images added via RenderImage are not displayed in the PrintPreview. However, when the exact same code is run with the project targeting .NET 8, the images are rendered and displayed correctly in the PrintPreview.

  In contrast, PrintDocument behaves as expected and displays images correctly in PrintPreview under both .NET 8 and .NET 9.

  Could you please confirm whether this is a known issue with MultiDocument under .NET 9, or if there are any additional compatibility requirements or workarounds that should be considered?

  Examlpe project is attached.
