Tracing on RoleEntryPoint

I had a hard time trying to get some diagnostics from a RoleEntryPoint.
I was doing some setup in this entry point and getting some errors.
So I tought, mmmm: this is a Task for the super Azure DiagnosticMonitor.

And I added a bunch of Trace statements and waited to get some output in my WADLogsTables,
but NOTHING!!! ZERO NILCH! NADA!!

What happenned!!!

I took me a while to get to it. So

This is the things. I had to do.

1. First add a file called WaIISHost.exe.config

2. Add the Azure Diagnostics Trace Listener

<?xml version="1.0"?>
<configuration>

  <system.diagnostics>
    <trace>
      <listeners>
        <add name="AzureDiagnostics" type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
          <filter type="" />
        </add>

      </listeners>
    </trace>
  </system.diagnostics>

</configuration>

3. And very very important, you must go to Copy to Output Directory property for this file and set it to Copy Always.

4. And another thing that you need is a lot of patience. The Diagnostics infraestructure takes a while.
So you add a Thread.Sleep after the Start call

DiagnosticMonitor.Start(storageAccount, configuration);
Thread.Sleep(10000);

5. After you do that you will be able to collect some information from the WADLogsTables
