Workflow Runtime Engine: Every running workflow instance is created and maintained by an in-process runtime engine that is commonly referred to as the workflow runtime engine. Host Process: When a workflow model is compiled, it can be executed inside any Windows process including console applications, forms-based applications, Windows Services, ASP.NET Web sites,… Continue reading
A Workflow is a set of activities, which is stored as model and they depict a process. Below figure depicts clearly the difference between Workflow and Activity.
