We strongly recommend that you use Microsoft Graph instead of Azure AD Graph API to access Azure Active Directory resources. Our development efforts are now concentrated on Microsoft Graph and no further enhancements are planned for Azure AD Graph API. There are a very limited number of scenarios for which Azure AD Graph API might still be appropriate; for more information, see the Microsoft Graph or the Azure AD Graph blog post in the Office Dev Center.

Question 42: To communicate with the worker role, a web role instance places messages on to a queue. A workerrole instance polls the queue for new messages, retrieves them, and processes them. There are acouple of important things to know about the way the queue service works in Azure. First, youreference a queue by name, and multiple role instances can share a single queue. Second, there is noconcept of a typed message; you construct a message from either a string or a byte array. Anindividual message can be no more than 64 kilobytes (KB) in size.
