Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month I discuss several design patterns used in WF.

As Visual Studio 2010 Beta1 is released, let’s take a quick walkthrough of the Workflow templates we are providing for the new Windows Workflow Foundation (WF) model provided in the System.Actvities.* namespace

WF4 beta 1 ships with a comprehensive set of activities (more than 35) that you can use to author your workflows or to create your own custom activities. This post will give you a quick tour through the activity palette and introduce you to the key characteristics of the out of the box activities.

These documents help .NET developers better understand and evaluate Windows Workflow Foundation (WF) in the Microsoft .NET Framework 4, and the impact of WF 4 on existing WF workflows and code.

This Code Gallery project contains the code samples to help .NET developers better understand and evaluate Windows Workflow Foundation (WF) in the Microsoft .NET Framework 4.

How do you cancel work in your application? Many middle tier components and services rely on transactions to handle cancellation for them. This makes a great deal of sense because transactional programming is well understood. However there are many times when you must cancel work that cannot be done under a transaction.

Keith Pijanowski's Blog: In that post I described Software as a Service, Platform as a Service and I concluded with a description of Software plus Services which is Microsoft’s marketing pitch on their PaaS and SaaS offerings.

Pronounced "Sharp Architecture," this is a solid architectural foundation for rapidly building maintainable web applications leveraging the ASP.NET MVC framework with NHibernate
