WCF data may contain multiple endpoints, each of which acts as an entry point for communication. Clients and servers exchange information through endpoints, as shown in the following figure:

Therefore, if we can get the details of the endpoint, it will help us to better analyze the definition, content and execution of the service.

There are two scenarios for services to publish their own WCF data. One is to provide metadata based on HTTP-GET protocol; the other is metadata exchange, which often uses a special endpoint, which is called metadata exchange endpoint. Metadata exchange endpoints, like other endpoints, still contain addresses, bindings, and contracts, but the service contract used is the interface IMetadataExchange provided by WCF.

In fact, these two ways of publishing WCF data represent that it uses two different standard protocols, the former for HTTP/GET requests and the latter for WS-MetadataExchange (MEX). In WCF data, the two metadata exchange modes are represented by the MetadataExchangeClientMode enumeration type:

Public enum MetadataExchangeClientMode {MetadataExchange, HttpGet} Thank you for your reading. The above is the content of "how to understand WCF data".
