Debug your custom SharePoint Server 2013 Workflows

The workflow team has worked with the Azure team to create a product called Workflow Manager. Workflow Manager hosts the latest version of the Windows Workflow Foundation runtime and all the necessary services in an available and scalable way. It takes advantage of the Microsoft Azure Service Bus for performance and scalability, and when deployed, it runs exactly the same in an on-premises deployment as in the cloud, similar to Office 365. SharePoint is then connected and configured to hand off all workflow execution and related tasks to the Workflow Manager farm.
