title: Nlog not creating file relative to website project
body: <p>I am using a website project, I added Nlog from Nuget, and used the following NLog configuration :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;nlog autoReload="true" 
        throwExceptions="true" 
        xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt;
      &lt;targets&gt;
          &lt;target name="logfile" xsi:type="File" fileName="log.txt" /&gt;
      &lt;/targets&gt;
  
      &lt;rules&gt;
          &lt;logger name="*" minlevel="Info" writeTo="logfile" /&gt;
      &lt;/rules&gt;
  &lt;/nlog&gt;
  </code></pre>
  
  <p>I ran ProcessMonitor and it shows that Nlog is trying to create log.txt in the IISExpress folder instead of my website project folder.</p>
  
  <blockquote>
    <p>C:\Program Files (x86)\IIS Express\log.txt</p>
  </blockquote>
  
  <p>How can I make NLog put my log file, <code>log.txt</code>, in my website project's folder instead of the IISExpress folder?</p>
