Examining the WF Engine Hosting Code

While our first example executes as expected, we have yet to examine the code that actually

project. Within the Main() method, you will find code that makes use of two primary types,

WorkflowRuntime and WorkflowInstance.

As the names suggest, the WorkflowRuntime type represents the WF runtime engine itself, while

WorkflowInstance is used to represent an instance of a given (pardon the redundancy) workflow

instance. Here is the Main() method in question, annotated with my various code comments:

static void Main(string[] args)
