Can Maui display a WinForms app that is built as a dll?

We have a WinForms application that loads sub applications as dlls. Can Maui load a dll that is a WinForm app and display it?

Off of Windows, the WinForms app won't run so the question is moot.
On Windows, Maui apps are WinUI3 apps running standard .Net. That the app uses Maui isn't particularly interesting to the WinForms code.
If your WinForms dll runs in standard .Net then it will load here. The hitch is that you can't readily mix the WinForms UI in a WinUI3 window - if your WinForms app is written assuming it's running on an existing WinForms thread then it probably won't work; if it's written to create its own then it likely well. WinForms specialists may have more info.
