A Basic Workflow Console Application

1. Create a workflow console application in VS2012.

2 By default a Workflow1.xaml file is generated in the project.

3. Drag and drop a Flowchart, a Flowdecision, an Assign to the designer.

4. Add variables and argument in workflow environment, make it look something like this.

 5. Edit Program.cs.

using System;
using System.Activities;
using System.Collections.Generic;
 
namespace WorkflowConsoleApplication1
{
 
    class Program
    {
        static void Main(string[] args)
        {
            // Prepare argument name:value pair Dictionary<string,object>, 
            //      where string is the variable name
            //      and object is the value of the variable
            var inArg = (IDictionary<string, object>)new Dictionary<string, object>();
            inArg.Add("Gender","Female");
 
            // Initialize the workflow. 
            Activity workflow1 = new Workflow1();
            // Invoke it by passing the argument name:value pair
            // and get the result in the same way.
            // Extract the result by specifying the name of the variable.
            Console.WriteLine(WorkflowInvoker.Invoke(workflow1, inArg)["Result"]);
            Console.ReadLine();
        }
    }
}

 6. Very ugly but simple enough and done.

One more thing, you can edit the Workflow1.xaml file in code by right-click the file and select view code.
