Methods

	Name	Description
	Equals(Object)	(Inherited from Object.)
	Finalize()	(Inherited from Object.)
	GetHashCode()	(Inherited from Object.)
	GetType()	(Inherited from Object.)
	MemberwiseClone()	(Inherited from Object.)
	SetBusy()	Sets the status of the role instance to Busy until the status is checked again, which occurs at regular intervals. When the status of the role instance is Busy it will not receive requests from the load balancer.
	ToString()	(Inherited from Object.)

Remarks

A role instance may indicate that it is in one of two states: Ready or Busy. If the state of a role instance is Ready, it is prepared to receive requests from the load balancer. If the state of the instance is Busy, it will not receive requests from the load balancer.

The following code example shows how to write out the status of the role instance:

public override bool OnStart()
{
   RoleEnvironment.StatusCheck += RoleEnvironmentStatusCheck;

   return base.OnStart();
}

private void RoleEnvironmentStatusCheck(object sender, RoleInstanceStatusCheckEventArgs e)
{
   Trace.WriteLine("The status of the role instance: " + e.Status, "Information");
}
