title: NLog: can't write to event log
body: <p>I can't write to the event log with NLog.  I've been able to write to the console and to a file.  I've turned on exceptions in NLog and am receiving no feedback from NLog.  </p>
  
  <p>Here is my NLog.config:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        throwExceptions="true"&gt;
      &lt;targets&gt;
          &lt;target name="console" xsi:type="Console" layout="${message}" /&gt;
          &lt;target xsi:type="EventLog" name="eventlog" layout="${message}" log="Application" source="aaaTest"/&gt;
          &lt;target xsi:type="File" fileName="log.txt" name="file"/&gt;
      &lt;/targets&gt;
  
      &lt;rules&gt;
          &lt;logger name="*" minlevel="Debug" writeTo="eventlog,console,file" /&gt;
      &lt;/rules&gt;
  &lt;/nlog&gt;
  </code></pre>
  
  <p>In Event Viewer, I am looking at "Event Viewer (Local)" > "Windows Logs" > "Application".  However, I see no instances of "aaaTest" (my defined source) in the log.</p>
