title: Writing orchestration by c#
body: <p>I was wondering if there is any way to create/modify an orchestration by code instead of drawing the boxes.
  I know that everything gets converted to c# code(or something very similar) in the .odx file. So is there a way to modify that code and have biztalk generate those drawings instead?</p>
  
  <p>Since my experience is much more in C/C#, the code approach is much more natural to me than drawing approach.</p>
  
  <p>BTW, I am NOT talking about writing custom pipelines or other external classes to be called from the orchestration, I already know how to do this. I really want to code the orchestration itself by code.</p>
