- serializationManager
An System.ComponentModel.Design.Serialization.IDesignerSerializationManager to use for loading state for the designers.
The BasicDesignerLoader.PerformLoad(IDesignerSerializationManager) method is invoked when the designer loader needs to load its state. BasicDesignerLoader.PerformLoad(IDesignerSerializationManager) is called before the BasicDesignerLoader.OnBeginLoad method. You must implement this method to load the designer contents.
