Windows Workflow 4.0 and Windows Server AppFabric – My Resources for Getting Started

31 Mar

I’m starting on a new feature of the application I work on in my day-to-day. We’re building out a feature to replicate some human workflows that are long running. Here’s some of the resources I have accumulated so far:

Introduction


Windows Workflow Foundation (WF) is a method of creating discrete activities that can be used to model the workflow of an application or human workflows. It “provides a programming model, in-process workflow engine and rehostable designer to implement long-running processes as workflows within .NET applications”.

With .NET 4.0, a new programming model as well as further integration between Windows Communication Foundation (WCF) and WF was created.

The tasks I am looking to automate are human activities that are often long-running such as follow-up processes as well as approval processes where an activity is performed, a duration expires or the workflow is preempted by further user input and then continues to completion. The Creating a Long-running Workflow Service article defines a durable workflow as a “long running workflow services may run for long periods of time. At some point the workflow may go idle waiting for some additional information. When this occurs the workflow is persisted to a SQL Server database and is removed from memory. When the additional information becomes available the workflow instance is loaded back into memory and continues executing.” These long running, durable workflows can be hosted in WCF Services (Hosting Options: self-hosted in a managed application, hosted in a managed windows service, in Internet Information Services [IIS], or Windows Process Activation Services [WAS]), Windows Servies (self-created or Windows Server AppFabric), or in the cloud (Windows Azure AppFabric).

    Had to edit this today (2011/04/07) as I came across the Windows Workflow Samples. Though the links are just a replication of the TOC from the Microsoft website, being able to see the list of samples at a glance was of huge value to me.
