Highlighter on .NET 4.7

This sample allows you to highlight C# source code. Highlighting is based on http://hilite.me web service, which is called from a background job in a truly asynchronous way – neither controller, nor any other entity is waiting for a completion. Results are delivered via WebSockets using SignalR.

   byte[] attachment = (byte[])null;
   string fileName = string.Empty;
   if (fileAttachment != null)
   {
       if (fileAttachment.ContentLength > 0)
       {
           attachment = new byte[fileAttachment.InputStream.Length];
           fileAttachment.InputStream.Read(attachment, 0, (int)fileAttachment.InputStream.Length);
       }
       fileName = fileAttachment.FileName;
   }

Console.WriteLine("Hello, world!");
