The children collection cannot be modified when a visual children iteration is in progress.

The AddVisual3DChild method is introduced in .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.

Notes to Inheritors

A class that derives from Visual3D must call this method to notify the Visual3D layer that a new child appeared in the children collection. The Visual3D layer then calls the GetVisual3DChild method.
