Impersonation is a technique that WCF Services use to authorize the caller’s identity to access to service resources such as files and database tables. Service resources can be located either on local service machine or remotely hosted. The resources are being accessed by WCF Service’s process identity or specific windows identity.

		<description><![CDATA[



Binding in WCF defines how clients can connect with your service. The base class for all bindings in WCF is System.ServiceModel.Channels.Binding. A Binding includes definition for WS-* protocols used, the message encoding and the transport protocol.
The available WCF Bindings are

wsHttpBinding
basicHttpBinding
netTcpBinding
netNamedPipeBinding
netMsmqBinding
wsDualHttpBinding






  
Consider the following scenarios when your are choosing the WCF Binding
