Remarks

The EditingContext class includes permanent state, such as a list of services that are running in the designer. It also includes transient state that consists of context items. Examples of transient context item state include the set of currently selected objects, and the editing tool being used to manipulate objects on the design surface. The editing context is designed to be a concrete class for ease of use. It does have a protected API that can be used to replace its implementation.

Thread Safety

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