Windows Communication Foundation what communication protocols are used to access the service, whether security mechanisms are to be used, and the like. WCF includes predefined bindings for most common communication protocols such as SOAP over HTTP, SOAP over TCP, and SOAP over Message Queues, etc. Interaction between WCF endpoint and client is done using a SOAP envelope. SOAP envelopes are in simple XML form, which makes WCF platform-independent.

Communication engines operate on the premise that the World Wide Web is too large for any one engine to index it all and that more productive results can be obtained by combining the results from several engines dynamically. This may save the user from having to use multiple engines separately.
