 When this code runs locally, `DefaultAzureCredential` searches a credential chain for the first available credentials. If the `Managed_Identity_Client_ID` is null locally, it will automatically use the credentials from your local Azure CLI or Visual Studio sign-in. You can read more about this process in the [Azure Identity library overview](/dotnet/api/overview/azure/Identity-readme#defaultazurecredential).

 You can also associate a user-assigned managed identity and a system-assigned managed identity to a resource simultaneously. This can be useful in scenarios where all of the apps require access to the same shared services, but one of the apps also has a very specific dependency on an additional service. Using a system-assigned managed identity also ensures that the identity tied to that specific app is deleted when the app is deleted, which can help keep your environment clean.
