E learning Workflow Foundation for ASP NET Developers Lesson 1(Part II) In this first lesson we will learn about the WorkflowRuntime Object. We will understand what a Scheduler Service does, the difference between the DefaultSchedulerService and the ManualSchedulerService. Its very important to understand how to create a communication channel between the Workflow project and the ASP.NET Application. To understand this communication in this lesson we will study the HandleExternalEvent activity and the CallExternalMethod Activity. These activities play an important part in our Page-flow solution. Finally we will start developing our solution creating a workflow project and implementing a contract and using the contract in the HandleExternalEvent Activity and in the CallExternalMethod activity.
