NetTcpBinding Class

A secure, reliable binding suitable for cross-machine communication.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class NetTcpBinding : Binding, 
	IBindingRuntimePreferences

The NetTcpBinding generates a run-time communication stack by default, which uses transport security, TCP for message delivery, and a binary message encoding. This binding is an appropriate Windows Communication Foundation (WCF) system-provided choice for communicating over an Intranet.

The default configuration for the NetTcpBinding is faster than the configuration provided by the WSHttpBinding, but it is intended only for WCF-to-WCF communication. The security behavior is configurable using the optional securityMode parameter in the constructor. The use of WS-ReliableMessaging is configurable using the optional reliableSessionEnabled parameter. But reliable messaging is off by default. More generally, the HTTP system-provided bindings such as WSHttpBinding and BasicHttpBinding are configured to turn things on by default, whereas the NetTcpBinding binding turns things off by default so that you have to opt-in to get support, for example, for one of the WS-* specifications. This means that the default configuration for TCP is faster at exchanging messages between endpoints than that configured for the HTTP bindings by default.

This example shows how to create a NetTcpBinding, setting the security mode and transport credential type.

	    NetTcpBinding binding = new NetTcpBinding();
	    binding.Security.Mode = SecurityMode.Transport;
	    binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Certificate;

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
