New Management Libraries

A new set of management libraries that follow the Azure SDK Design Guidelines for .NET and based on Azure.Core libraries are now in Public Preview. These new libraries provide a number of core capabilities that are shared amongst all Azure SDKs, including the intuitive Azure Identity library, an HTTP Pipeline with custom policies, error-handling, distributed tracing, and much more. You can find the list of new packages on this page.

To get started with these new libraries, please see the quickstart guide here. These new libraries can be identifed by namespaces that start with Azure.ResourceManager, e.g. Azure.ResourceManager.Network
