The primary reason I've applied this FlushMode is because I've incorporated
the CpBT model. There are a number of places where it is mentioned that
this works with the FlushMode.Never setting, e.g.
http://fabiomaulo.blogspot.nl/2008/12/identity-never-ending-story.html.
And, of course, the uNhAddIns applies this in its implementation in
https://code.google.com/p/unhaddins/source/browse/uNhAddIns/uNhAddIns/SessionEasier/Conversations/NhConversation.cs
with:
private static void EnsureFlushMode(ISession session)
{
if (session.FlushMode != FlushMode.Never)
{
log.Debug("Disabling automatic flushing of the Session");
session.FlushMode = FlushMode.Never;
}
}
