How to discover role instances in Azure?

Question

The code below only prints one instance id per instance even though I'm running 4 instances. Is this a bug in development fabric or this is how it is supposed to be?

public override void Run()
{
    foreach (RoleInstance roleInst in RoleEnvironment.CurrentRoleInstance.Role.Instances)
    {
        Trace.WriteLine("Instance ID: " + roleInst.Id);
    }
}

Answer 1

You need to have at least one internal endpoint for all the role instances to show up.
