Daily Interview Question #3: What are the MEPs available in WCF?

By Francis   Posted at   11:12 PM   ASP.Net Interview Questions No comments
              MEP is the short form for Message Exchange Pattern. In Windows communication foundation, 3 types of Message exchange patterns are allowed. They are:


  1. Data Gram
  2. Request and Response
  3. Duplex

Datagram, is often called as "fire and forget". There is no guarantee, whether the message delivered or not. 

Request and response, indicates every request have its response. Unlike the first one it provide guarantee for the message.

Duplex mode look like a chat application.
