Azure queue - can I verify a message will be read only once?

Question

I am using an Azure queue and have several different processes reading from the queue.
My system is built in a way that assumes each message is read only once.
This Microsoft article claims Azure queues have an at least once delivery guarantee which potentially means two processes can read the same message from the queue.
This StackOverflow thread claims that if I use GetMessage then the message becomes invisible to all other processes for the invisibility timeout.

Assuming I use GetMessage() and never exceed the message invisibility time before I DeleteMessage, can I assume I will get each message only once?

I think there is a property in queue message named DequeueCount, which is the number of times this message has been dequeued. And it's maintained by queue service. I think you can use this property to identify whether your message had been read before.
