An implementation of the IIdentityProvider interface is used to obtain the IIdentity instance to use to return the PrincipalIdentityName of the TransportMessage.

There is a DefaultIdentityProvider that is used if no other instance is provided.



IIdentity Get();

The method will return the IIdentity instance to use.

Note: the IIdentityProvider implementation is responsible for honouring the IServiceBusConfiguration.CacheIdentity property.
