BasicHttpBinding vs. WSHttpBinding

ref:Difference between basichttpbinding and wshttpbindings Difference between BasicHttpBinding and WSHttpBinding BasicHttpBinding

1.  WS-I Basic Profile 1.1 specification (Old ASMX style)
 2.  It supports SOAP 1.1 as a messaging protocol
 3.  Doesn’t support WS-Security, and the entire payload is 
     sent in plain text.
 4.  Offers great level of interoperability.

WSHttpBinding

1.  Allows you to use various WS-* specifications such as
     WS-Security 1.1, WS-Reliable Messaging etc
 2.  It supports SOAP 1.2 as a messaging protocol
 3.  As its built using WS-* specifications, it does not support 
     wider ranges of client.

WSHttpBinding more secure and reliable than BasicHttpBinding. Finally, if compatibility is not required, WSHttpBinding is the choice. - Mahesh
