title: How to use Serilog ForContext
body: <p>I am new to Serilog and I am having a hard time figuring out how to use the context functionality. When I run the code below the output file does not include the the report id. Any ideas what I am missing?</p>
  
  <pre><code>var logger = new LoggerConfiguration()
                  .WriteTo
                  .File(@"C:\Log.txt")
                  .CreateLogger()
                  .ForContext("Report ID", 10);
  
  logger.Information("Test"); 
  </code></pre>
