title: Fiddler not capturing requests from C# application
body: <p>I was trying to run Fiddler (v4.6.0.2, built August 17, 2015) to capture outgoing requests from a C# WebAPI application (.NET 4.5.2) to Amazon web services.</p>
  
  <p>I have set the proxy configuration in web.config (the application is running under my domain user account) as per the <a href="http://docs.aws.amazon.com/AWSSdkDocsNET/latest/V3/DeveloperGuide/net-dg-config-ref.html" rel="nofollow">Amazon documentation</a> as well as the <a href="http://www.telerik.com/blogs/capturing-traffic-from-.net-services-with-fiddler" rel="nofollow">Telerik documentation</a>:</p>
  
  <pre><code>&lt;aws region="us-west-2" profileName="xxxxxxxxxxxxxx"&gt;
    &lt;proxy host="127.0.0.1" port="8888"/&gt;
  &lt;/aws&gt;
  
  &lt;system.net&gt;
    &lt;defaultProxy enabled="true"&gt;
      &lt;proxy usesystemdefault="False" bypassonlocal="False" proxyaddress="http://127.0.0.1:8888" /&gt;
    &lt;/defaultProxy&gt;
  &lt;/system.net&gt;
  </code></pre>
  
  <p>When Fiddler runs, it dutifully captures all traffic coming from my browser. I know that my application is routing its web requests properly because if I turn Fiddler off, I get exceptions due to being unable to connect to the proxy. However, the problem is none of the application's requests to Amazon are showing up in Fiddler. I turned off all filters in Fiddler to make sure I hadn't accidentally hidden those requests.</p>
  
  <p>I also tried it in a Windows console application connecting to internal web services and I had the same behavior. Am I missing any other settings? Thanks.</p>
