Assembly: System.ServiceModel (in system.servicemodel.dll)
The virtual path to the service.
A service at given virtual path cannot be found.
The service fails to activate successfully.
The service is not running in the hosted environment.
virtualPath is a null reference (Nothing in Visual Basic).
virtualPath is an absolute URI or not valid.
This method is used by third-party transport developers to activate the service at the provided virtual path if that service is not already active. This method is idempotent so that once it has been called, calling it again with the same virtualPath specified is safe in the sense that it has no effect.
