title: Get filename of current configuration file
body: <p>I'd think this would be simple, but I can't find an answer.</p>
  
  <p>I'm using remoting and I want to store the RemotingConfiguration in the app.config. When I call <code>RemotingConfiguration.Configure</code> I have to supply the filename where the remoting information resides. So... I need to know the name of the current configuration file.</p>
  
  <p>Currently I'm using this:</p>
  
  <pre><code>System.Reflection.Assembly.GetExecutingAssembly().Location + ".config"
  </code></pre>
  
  <p>But this only works for windows applications, not for web applications.</p>
  
  <p>Isn't there any class that can supply me with the name of the current config file?</p>
