I receiving IOrganizationService from external factory. I need to know if any caller Id was set on received interface. How can I accomplished it? I can check type of my interface: if is is CrmServiceClient then check CallerId explicit and so on - I know but it requires to check every possible type. I wondering if ther is eny sdk message to check if eny behalf user is currently set on my IOrganizationService? I will be grateful for any idea...
