Why is this needed:
Without this, there is an indirect dependency on the older packages as HealthChecks packages depend on them.
I'm not sure how both can be maintained, as there are going to be customers who would use both - it would be some time before the old Microsoft libraries are outdated.
What would you like to be added: Azure has started releasing a new set of libraries which are in the Azure.{area}.{service} namespace, rather than the Microsoft.{service} namespace. An example is messaging here: https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/eventhub/Azure.Messaging.EventHubs/MigrationGuide.md
It would be good if this is supported.
