Remarks

OleMenuCommandService is automatically offered by the Package class (to offer global commands for an entire package), and it is also offered by the WindowPane class (to offer commands for the current window). This offering is always done via the service container, so anyone deriving from the Package or WindowPane classes can remove or replace the default implementation of this class. This class uses several other services. All of these services are optional, so the class's behavior will degrade if one or more services are missing. The following table shows which services are used and for what purpose:

Service

Use

ISelectionService

Used to discover the current selection in order to obtain verbs offered by the currently selected designer.

IDesignerHost

Used to obtain the designer for the currently selected component, if any.

IVsUIShell

Used to notify Visual Studio that the command status has changed.

Used to execute global commands

OleComponentUIManager

Used to show context menus

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.
