• The new Windows Workflow Foundation 4 runtime
  
  With WF3 there was a central workflow runtime environment called the WorkflowRuntime and used to manage the lifetime of workflow instances. Like recording workflow errors, tracking execution or workflow persistence must be done for each instance while before we could just do it on the workflow runtime. Basically we had to add a different scheduler to the workflow runtime and explicitly tell the scheduler to execute the workflow. In WF4 this central class no longer exists and we manage individual workflows. using (WorkflowRuntime workflowRuntime = new WorkflowRuntime()). {.

• Using Model – View – ViewModel with Silverlight
  
  All UI control properties that need to change at runtime do so by data binding to a ViewModel property. The View – Model – ViewModel design pattern, also known as MVVM, is getting more popular these days. have found it extremely easy to use when developing very different applications and have used the design pattern recently in both ASP.NET, WPF and Silverlight applications. However easy as it might be is seems to confuse people as I have seen some terrible examples where people make a complete mess of things. The View is data bound to a ViewModel. The ViewModel is just another class.

• Getting started with Windows Workflow Foundation 4
  
  That might be a bit surprising, after all we still have activities and a workflow runtime right? You might need a bit of luck because it appears the current bits are still a bit unstable and on my laptop running Windows 7 the designer tends to lock up quite a bit In the next post more about how the workflow is created and started at runtime. As you may have heard Windows Workflow Foundation 4 is not an upgrade from Windows Workflow Foundation 3 (or 3.5). In fact Windows Workflow Foundation 3 was the first version and 3.5 added only very few features and some bug fixes.

• Using WF4 bookmarks with IWorkflowInstanceExtension
  
  But that also means they are not aware of the workflow runtime environment and can’t do much more that respond to calls from a workflow. With the required extension done we still need to make sure it gets added to the workflow runtime of choice. Note: This blog post is written using the.NET framework 4.0 Beta 2 In this previous blog post I showed how to create an asynchronous activity using the NativeActivity and CreateBookmark to pause a workflow execution. Using that in a WorkflowApplication was easy but what about WorkflowInvoker or WorkflowServiceHost? return null ; }. Enjoy!

• Loading XAML Workflows in WF4
  
  Its nice and easy, you design the workflow, compile it and at runtime there is a.NET type you use to create and run workflows. The main drawback is that this approach isn’t very flexible, sometimes you want to be able to change your workflow definition at runtime or store it in a database so recompiling isn’t an option. Note: This blog post is written using the.NET framework 4.0 RC 1 Most of the time I used compiled workflows in Windows Workflow Foundation 4. Fortunately we can also load a workflow from the XAML file itself and execute the resulting workflow activity. Enjoy!

• Changing the Icon on a custom activity designer
  
  protected override void Execute(CodeActivityContext context). {. // Obtain the runtime value of the Text input argument. Note: This blog post is written using the.NET framework 4.0 Beta 2 When I create custom activity designers the icon that appears is usually one of the first things I want to change. Doing so in WF4 isn’t hard once you know where to look but if you don’t can be a bit of a challenge. Suppose I have a simple write line activity like this: [Designer( typeof (MyWriteLineDesigner))]. string text = context.GetValue( this.Text); Console.WriteLine(text); }. }. Sweet. Enjoy!

• Accessing Context Properties from within a map in BizTalk
  
  It is not a 100% clean construct because BizTalk really tries to do its best to disallow access to internal classes and runtime. It's been a while, but i hope this will make up for being quiet again. I've run across the question many times, but never found the time to really dive into it. Now that time was found. And attached is the result. However, utilitzing some thread local storage and (what i think is) a reasonable assumption, this functoid is actually able to retrieve any of the message context properties in a receive port (no orchestrations required) ContextAccessor.zip (255.35
