Marking a series of service bus messages as START and END of a sequence

Query/Question Problem Statement: I am publishing a series of messages to a service bus topic. Let’s say I have messages 1 to 100. They are all different messages in themselves but they are part of a series. I know we can set that series by using sessions(same session id for all those messages). But is there a way to say that message 1 is the start of that series and 100 is End of that series. Adding custom sequence numbers will allow me to achieve the same behavior but is there something which service bus provides to achieve that kind of sequencing?

Environment:

• Name and version of the Library package used: Microsoft.Azure.ServiceBus 4.1.1
• Hosting platform or OS and .NET runtime version (dotnet --info output for .NET Core projects): Azure AppService - .Net Core 3.1
• IDE and version: Visual Studio 16.5.4

@Sandeep321, if you require all 10 messages to be received prior to taking any action and the last message should be a marker message, sessions are what you need. When you receive messages in a session, you can have a session state which could store the information from the previous 9 messages until the last, 10th, is processed.

Look at subscriptions. Receive operations with sessions are only possible on the entities that can be used to receive messages (queues and subscriptions).
