Can I combine calls in WCF?

Question

I have two methods that I need to call in my WCF application from the client.

Authentication (username, password) GetUser (username)

Can these calls be combined to avoid so many calls being sent back / forth?

Answer 1

There are several ways to deal with this type of thing. First, you can use WCF sessions to run a group of commands that need to maintain some context between calls:

Secondly, you can use WCF support for WS-Security standards to avoid having to pass credentials as a second call:

Answer 3

I would recommend taking a look at Agatha , a framework created by Davy Brion . It is built on top of WCF and implements a message / response style. In particular, it allows you to combine queries to minimize round trips.
