Chapter 11. Workflow > Creating a Workflow Using Visual Studio 2010
Creating a Workflow Using Visual Studio 2010
With our pluggable workflow service and external calculation engine up and running, we can create a basic workflow in Visual Studio that will send messages to the calculation engine. Our test workflow will be very simple; when a new item is added to a list, its title will be sent to the calculation engine. We will then be able to trigger a response manually from the calculation engine, which will be passed to the workflow. The workflow will log the response and complete.
We can add our workflow to the WorkflowDemonstration solution that we created earlier. In Visual Studio, select Project | Add New Item. From the Add New Item dialog, select SharePoint | 2010 | Sequential Workflow. Name the new workflow External Calculation, as shown:
In the SharePoint Customization Wizard dialog, leave the default name as WorkflowDemonstration - External Calculation. We can see that the same types of workflow that are available in SharePoint Designer are also available for Visual Studio workflows: List Workflow and Site Workflow. Since we’re planning to use data in a list to trigger our workflow, set the type to List Workflow.
Accept the default association settings. This will associate our workflow with the Products list that we created earlier. Click Finish to complete the process.
