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.
