Detaches one or more Classic Load Balancers from the specified Auto Scaling group.

Note that this operation detaches only Classic Load Balancers. If you have Application Load Balancers, use DetachLoadBalancerTargetGroups instead.

When you detach a load balancer, it enters the Removing state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the load balancer using DescribeLoadBalancers. Note that the instances remain running.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to DetachLoadBalancersAsync.
