How to do it...

  1. Open the workflow designer project:

    Open the workflow designer project we created in the previous task.

  2. Create a new empty workflow as an empty workflow template:

    Click on the Show All Files button and navigate to the project's bin\Debug folder.

    Create a new XAML file named WFTemplate.xaml. Fill the file with the following XAML code:
