Filip,
>Upgrading to MM v2.2 all our Windows Forms using OakLeaf.MM.Main.Windows.Forms have been "degraded" to ordinary classes; unable of showing their GUI. However they still possess their .Designer.cs files.
Did you follow the instructions in the What's New Guide for removing references to MM .NET assemblies from your project and adding them back in again?
