How to update the Registration Time To Live for an Azure Notification Hub?

I have a Notification Hub in Azure. After creation the Registration TTL is set to forever. I would like to limit it to 90 days.

I have tried to update the Registration TTL on Azure Portal, Azure CLI and via the C# SDK: NotificationHubCreateOrUpdateParameters() to update the RegistrationTtl without success. It seems to me that this was working few years ago but not now.

Solution

  • I will answer my own question because I have found a way to update the RegistrationTtl:

    var namespaceManager = NamespaceManager.CreateFromConnectionString("connectionstring");
NotificationHubDescription hub = namespaceManager.GetNotificationHub("foo");
hub.RegistrationTtl = TimeSpan.MaxValue;
namespaceManager.UpdateNotificationHub(hub);
