title: Serilog Selflog write exception data only once to file
body: <p>I am using asp.net MVC application. In the my application, I need fetch   internal exception data of the serilog. Serilog provides get the exception data from the following code:</p>
  <pre><code>Serilog.Debugging.SelfLog.Enable(TextWriter.Synchronized(file));
  HiTrustLog.HiTrustLogger.Information(log);
  Serilog.Debugging.SelfLog.Disable();
  </code></pre>
  <p>Serilog Library writes to file exception data only once and second time onwards not writing.
  Just, I needs it write exception data when internal exception occurs</p>
