Chapter 1: Workflow Program

In this chapter we will see how to create WF program with different methods.

Debugging a WF program

In this task, we will debug a WF program.

How to do it...

1. Create a Workflow project:
   Create a new Workflow Console Application project under the Charpter01 solution. Name the project as DebugWFProgram. In the opening WF designer panel, author a Workflow as shown in the following screenshot:
   
   
   
2. Create Workflow host code:
   Open Program.cs file and change the code to:
   

   using System.Activities;

   using System.Activities.Statements;

   namespace DebugWFProgram

   {

       class Program

       {

           static void Main(string[] args)

           {

               WorkflowInvoker.Invoke(new Workflow1()

               {

                   InMessage = "In Message"

               });

           }

       }

   }
   

3. Set a debug break point:
   Right-click an activity and select Breakpoint | Insert Breakpoint to add debug break point.
   
4. Debug it:
   Press F5 to debug the WF Program; we can refer the following screenshot:

We can also debug an XAML Workflow. Open Workflow with the XML editor, insert some breakpoints, then press F5; we will see the breakpoints as shown in the following screenshot:
