IProfferService Interface


Enables a VSPackage to offer new services through the Visual Studio environment that are not implemented natively by the environment. In effect, it provides the mechanism through which VSPackages can contribute to the environment. The IProfferService interface is part of SProfferService.

VSPackage creators must register in the Windows registry the services it makes available through the environment in order to make them accessible to users. User then obtains the service by calling QueryService. For more information, see Managing VSPackages.

A VSPackage cannot replace the implementation of a service that is already provided by the environment or another loaded VSPackage. Therefore, if a service is already provided at the time an attempt to proffer the same service is made, the ProfferService method will fail.


ProfferService(Guid, IServiceProvider, UInt32)

Allows the caller to proffer a new service to the set of services presently proffered by the environment, either natively or by other installed VSPackages.
