The TCP-Centric WCF Bindings

Binding Class

Binding Element

Meaning in Life

NetNamedPipeBinding

A secure, reliable, optimized binding for on-

the-same-machine communication between

.NET applications

NetPeerTcpBinding

Provides a secure binding for P2P network

applications

NetTcpBinding

A secure and optimized binding suitable for

cross-machine communication between .NET

applications

The NetTcpBinding class uses TCP to move binary data between the client and WCF service. As

mentioned, this will result in higher performance than the web service protocols, but you are lim-

ited to an in-house Windows solution. On the plus side, NetTcpBinding does support transactions,

reliable sessions, and secure communications. 

Like NetTcpBinding, NetNamedPipeBinding supports transactions, reliable sessions, and secure

communications, but it has no ability to make cross-machine calls. If you are looking for the fastest

way to push data between WCF applications on the same machine (e.g., cross-application domain

communications), NetNamedPipeBinding is the binding choice of champions. As far as

NetPeerTcpBinding is concerned, consult the .NET Framework 3.5 documentation for details

regarding P2P networking. 

MSMQ-Based Bindings

Finally, if you are attempting to integrate with a Microsoft MSMQ server, the NetMsmqBinding and

MsmqIntegrationBinding bindings are of immediate interest. We will not examine the details of

using MSMQ bindings in this chapter, but Table 25-5 documents the basic role of each.
