You can totally do this, I don't know what these other answers are about, but they are way off!

Just do something like:

_host = new ServiceHost(...);
// Remove existing behavior as it is readOnly
for (int i = 0; i < _host.Description.Behaviors.Count; i++)
{
    if (_host.Description.Behaviors[i] is AspNetCompatibilityRequirementsAttribute)
    {
      _host.Description.Behaviors.RemoveAt(i);
      break;
    }
}
// Replace behavior with one that is configured the way you desire.
_host.Description.Behaviors.Add(new AspNetCompatibilityRequirementsAttribute { RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed });
_host.Open();

-- Edit This removes the existing behavior if it exists, and then adds a new behavior that has the mode you prefer. My example sets it to .Allowed, but you could of course set it to the mode you desire.
