WAS hosting is used to host the application on IIS with different protocol along with HTTP. WAS hosting is available in IIS 7 onwards where we have ability to mention the protocol to be used for any website we have created.

To host the service on WAS, simply create a website in IIS and go to Manage Websites > Advance Settings and at the Enable Protocols write the command separated values like "http, tcp" and this website can be used by both http and tcp protocol.

WAS is generally used when the WCF service has to be consumed locally (in the intranet environment).

The benefit are

1. In self hosting the dependency is on the system to start and stop
2. in IIS only http protocol can be used

IN WAS as soon as system starts, the WAS starts and no need a controller app to start and stop the service

It can be hosted on multiple protocol.
Because it can be hosted on multiple protocols such as TCP, it is faster than others.
