title: Dealing with a longer running process in WCF
body: <p>In the app I'm currently working on we are using a couple of WCF services with a lot of methods. Until now, all methods are very short running, often just getting some data. I've just added a method that takes a way longer time to run. </p>
  
  <p>I do not want to raise the timeout in the config, because 1 minute is long enough for all other methods on the service. </p>
  
  <p>What is the best way to deal with 1 longer running method? And how do I provide feedback that it is still running? </p>
