According to MSDN , the “MaxConnections” parameter means:
The NetTcpBinding.MaxConnections
property controls the maximum number
of connections to be pooled for
subsequent reuse on the client and the
maximum number of connections allowed
to be pending dispatch on the server.
what does the term “Pending Dispatch” mean?
In WCF, “dispatch” is the process of deciding which method to call given an incoming SOAP message. A “pending dispatch” means that the server hasn’t finished deciding which message is the right one to send. The value of
MaxConnectionsdetermines how many of these decisions the server can be making simultaneously, at maximum.
