The StructuredCompositeActivityDesigner is the base class for all designers that contain child designers and the child designers are connected to each other using lines rendered on the design surface, called connectors. The class is provided so that activity designer developers can provide a number of activity designer layout types, rather than being tied to the layout provided in the CompositeActivityDesigner class.

.NET Framework

Supported in: 4, 3.5, 3.0

Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
