Using the Azure SDK for .NET, you need a simple way to retrieve an approximate count of messages in a queue named queue1. Which method requires the least development effort to get that approximate number?

The GetProperties method of the QueueClient class provides queue metadata, including an approximate message count, with minimal development effort. This method directly retrieves the ApproximateMessagesCount property, which is suitable for general monitoring and doesn't require processing individual messages. The GetProperties method of the QueueServiceClient class operates on the service level, not a specific queue, so it cannot provide a count for queue1. The PeekMessages method of the QueueClient class retrieves actual messages without removing them, which is not designed for counting and can be resource-intensive for large queues. The GetStatistics method is not a standard method for Azure Queue Storage clients in the .NET SDK.
