Consuming Multiple Webservices at once

I´ve been checking Kayak.com and many other comparison websites were they create on demand queries to multiple web services in order to display best results. I was wondering which is the best strategy to consume multiple web services at once like these website do. thank you so much. sebast开发者_开发技巧ian.

You will need Threading in one form or other.

Using FX <= 3.5, use the ThreadPool

From 4.0 on, you can use Tasks to get better control over it.
