After the operation completes, use the DescribeTrafficSources API to return details about the state of the attachments between traffic sources and your Auto Scaling group. To detach a traffic source from the Auto Scaling group, call the DetachTrafficSources API.
For .NET Core this operation is only available in asynchronous form. Please refer to AttachTrafficSourcesAsync.
