• WF and ASP.NET - A Few Gotchas
  
  ASP.NET as WF host is an important and useful scenario for WF adoption, but there are some interesting details that are worth understanding before you tackle this yourself. The first thing to understand is that WF itself imposes no specific threading model; rather, it must be configured to conform to any specific threading requirements of its host process. The default WF scheduler also uses the ThreadPool to execute individual workflows; in combination this would be bad, as it results in 2 ThreadPool threads consumed per web request. inside such workflows.

• Flowcharts in Workflow 4 and the Switch activity
  
  Flowcharts are a nice addition to Windows Workflow Foundation 4. They allow for a lot of pretty complex behavior that is hard to do in a sequential workflow. In WF 3 we used to model these complex behaviors as state machine workflows. Enter the flowchart in Windows Workflow Foundation 4 One of the good things is that a flowchart is not another workflow type. No it is just another activity to drop in a workflow. So you are free to combine sequential work with a flowchart in one workflow. Tags: NET Workflow WF4 VS2010 So far so good.

• NativeActivity – A Tricky Beast
  
  I’m writing Essential Windows Workflow Foundation 4.0 Here you have the ability to implement the async pattern (BeginExecute / EndExecute) to perform short lived async operations where you do not want the workflow persisted (e.g. This gives you full access to the power of the workflow execution engine. We could use a Thread.Sleep to do the delay but this would not be good for the workflow engine: we block a thread it could use and there is no way for the engine to persist the workflow – what if we wanted to retry in 2 days?

• Executing Workflows from XAML Files
  
  Seeing as this has changed completely from WF 3.5 I thought I’d post a quick blog entry to describe how to run a workflow declared in a XAML file. You may have heard that the WF 4.0 However, the Visual Studio 2010 workflow projects store the XAML as a resource in the binary rather than as a text file. So if you want to deploy your workflows as XAML text files how do you run them? you could pass the workflow runtime an XmlReader pointing at the XAML file but in WF 4.0 Tags: NET;WF;WF4 default authoring model is now XAML. In.NET 3.5

• Data and Windows Workflow Foundation 4
  
  One thing that has completely changed in Windows Workflow Foundation is the way we work with data in a workflow. In WF 3 we used properties to store data. Dependency properties left the way data was stored to be handled by the workflow runtime but in our program we could use them just like any other property. In WF 4 this has all changed! The actual data is stored somewhere inside of the workflow using a LocationEnvironment. To store some data inside of your workflow we need to add a Variable to the workflow or one of the nested activities.

• Using Windows Workflow Foundation 4 Receive from an non WF client
  
  In a previous blog post I described how to use the WorkflowServiceHost and host a workflow with a Receive activity that waits for WCF messages. However a lot of clients out there are not going to be workflows but “regular” code that calls into out workflow. In our workflow the operation is named “Operation1” and our service contact name was “MyService” with the default namespace of “ [link] ”. Using these WCF definitions creating a simple console app that calls the workflow is a breeze. Tags: NET NetFx3 Workflow WCF WF4 VS2010 interface MyService. {.

• Significant Advances in Unit Testing Windows Workflow
  
  This post describes a unit testing library for testing Windows Workflow Foundations. First a Little History: Last September I posted this teaser entitled Unit Testing Coming to a Workflow Near You. In that previous post, I highlighted what I could determine to be the current state-of-the-art with regard to unit testing workflows, circa September 2008. Unit Testing Activities with Windows Workflow Foundation by Ron Jacobs. TDD and Windows Workflow Foundation by Ron Jacobs. Unit Testing Workflow Activities by K. Note: This only applies to WF 3.0/3.5.
