mmFactoryDesktop not in 2019?

In converting my mm 2010 projects to mm 2019, I have run across my code implementing mmFactoryDesktop. I tried using mmFactory, I get an error:

System.InvalidCastException: 'Unable to cast object of type 'Ambit.POS.Main.Factory' to type 'OakLeaf.MM.Main.Windows.Forms.ImmFactoryWinForms'.'

I can't find any references in the help file to ImmFactoryWinForms. I have included MM.NET Framework Windows Forms 2019, but I don't can't find the factory I need to override.

Thanks,

Jeff

It may be that it's in the MM .NET 4.8 Dev Guide. We usually put instructions for upgrading in each Dev Guide, so you would need to go through each Dev Guide starting with the version you're moving from, through the version you're moving to. You can download the MM .NET 4.8 Dev Guide from the Downloads section of our web site. Here's a screenshot of the section I'm talking about:
