[FONT='Verdana','sans-serif']When the Windows Workflow Foundation (WF)*was first introduced in the .NET Framework 3.0, the only way to host a workflow in a client application was to use the [FONT='Verdana','sans-serif']WorkflowRuntime[/FONT] class programmatically, start the runtime, and create/start an instance of a workflow.* Furthermore, if you wanted to communicate between the client code and the workflow logic, you needed to ues a [FONT='Verdana','sans-serif']ExternalDataExchangeService[/FONT].* This required a fair amount coding effort to get even the simplest of workflows up and running.* The .NET Framework 3.5 introduced Workflow Services which are Windows Communication Foundation (WCF) Services authored as workflows.* Workflow Services give you a new way to accomplish this scenario using a much simpler,*cleaner, and arguably more elegant approach.* In this three part screencast, I show you how to improve on the more*manual hosting + ExternalDataExchangeServices approach to hosting a workflow in a client executable*using Workflow Service*by:[SIZE=+0][/FONT]
[FONT='Verdana','sans-serif']Part I - Reviewing the SimpleExpenseReport application from the Create a Sequential Workflow tutorial so we can compare the two approaches.* The application explicitly hosts the WorkflowRuntime & uses ExternalDataExchangeService
Part II - [/FONT][FONT='Verdana','sans-serif']Walking through the fundamentals of creating a Workflow Service and h[/FONT][FONT='Verdana','sans-serif']osting the Workflow Service locally[/FONT]
[FONT='Verdana','sans-serif']Part III - Walking through my rewrite of the SimpleExpenseReport application using Workflow Services.
Source code for the Workflow Services version of SimpleExpenseReport is available*at http://cid-1f72da7294089597.skydriv...CF_WF/SimpleExpenseReportWorkflowServices.zip.[/FONT]
