Hello Workflow

Creating a Simple Hello Workflow Application

We will create a very simple workflow that will be the equivalent to this code:

C#

private static void SayHello()

{

  Console.WriteLine("Hello Workflow 4");

}

Visual Basic

Private Shared Sub SayHello()

  Console.WriteLine("Hello Workflow 4")

End Sub

1. Start Microsoft Visual Studio 2010 from Start | All Programs | Microsoft Visual Studio 2010.
2. Create a new project in Visual Studio 2010 of type Workflow Console Application (under the Workflow project type) in either the Visual C# or Visual Basic projects Templates list. Ensure .NET Framework 4 is selected as the target runtime, and name it HelloWorkflow. Name the solution Begin, set the desired location, and click OK.

3. Since your business process is a 1 step process, you can simply add a WriteLine activity to implement the process. From the Toolbox, drag a WriteLine activity and drop it on the design surface.
   

   

   Adding a WriteLine activity

   Note: If the Toolbox window is not visible, select Toolbox from the View menu.
4. Set the WriteLine Text property to "Hello Workflow 4".
   

   

   Setting the Text property

   Note: The WriteLine activity is a simple activity that will display a message on the console. The text property is an Expression which could be the result of calling a function or evaluating the property of an object. In this case, the expression is a literal string so you must quote the string.
5. Press CTRL+F5 to build and run the workflow without debugging. The application should run in a console window and print the message “Hello Workflow 4”.
