Question

Is it possible delay making a virtual machine role available untill startup tasks complete?

I have a few tasks I need to complete on virtual machine start before the machine can safely be added to the load balancer. Is there a way to do this?

Found the solution. In the VM Role Startup windows service I can handle the RoleEnvironment.StatusCheck event. I can then call SetBusy() to tell prevent the instance being available in the load balancer.

    private void RoleEnvironmentStatusCheck(object sender, RoleInstanceStatusCheckEventArgs e)
    {
        if (this.busy)
        {
            e.SetBusy();
        }
        statusCheckWaitHandle.Set();
    }
