Where is RegisterInstance<IServiceBus at?

[DotNetSyndrome]

Sorry, 

I have been looking in the object browser for the following type Unity DI registration;

RegisterInstance<IServiceBus> 

It is displayed on this page...

http://masstransit.readthedocs.org/en/latest/configuration/containers.html

I can't seem to find this

Nevermind, they are part of UnityContainerExtensions. But for some reason Resharper Intellisense doesn't display cont.RegisterInstance<>, it only displays cont.RegisterInstance()
