• Rehosting the Workflow Designer in WF4
  
  Beta 2 With Windows Workflow Foundation 3 it was possible to rehost the workflow designer in your own application. With Windows Workflow Foundation 4 live has become much better on the rehosting front In fact it is possible to create the fully functional and useful workflow editor below in about 200 lines of code. And loading or saving a workflow is easy to, all it takes is a Load() and Save() function pointing to a XAML file. One thing that is needed is to register the workflow activity designer metadata. Validating the workflow. Sweet.

• Converting a C# workflow into XAML
  
  A interesting question that came up last week was how to convert workflows defined in C# to XAML. co worker of one of the attendees of the Essential Windows Workflow Foundation 4 course had been experiencing a lot of problems with the workflow designer and decided to create their workflows in C# instead of using the designer to generate XAML. While these workflows run just fine you do lose the visual aspect of the designer, one of the benefits of workflow in the first place. Take the following workflow defined in C#. Enjoy!

• Workflow Receive activity and message correlation
  
  With WF4 it is quite easy to use data that is part of the request message, for example an order identifier, to route multiple WCF messages to the same workflow. It is also possible to have multiple messages that can start a new workflow. In this blog post I am going to show both these concepts in a single workflow. This workflow is going to be able to receive three different messages, AddItem, AddExpensiveItem and Submit. Either AddItem or AddExpensiveItem can start a new workflow while Submit can only be done with an existing workflow. ReferenceID0.

• Executing Workflows from XAML Files
  
  I thought I’d post a quick blog entry to describe how to run a workflow declared in a XAML file. default authoring model is now XAML. 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 DynamicActivity dyn = new DynamicActivity(); // this line wires up the workflow creator method. In.NET 3.5

• Loading XAML Workflows in WF4
  
  RC 1 Most of the time I used compiled workflows in Windows Workflow Foundation 4. 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. Fortunately we can also load a workflow from the XAML file itself and execute the resulting workflow activity. Enjoy!

• What's New in Windows Workflow Foundation in.NET 4.5 (part 1)
  
  Search Searching through workflows is another big one. With small workflows it is quite easy to see where a variable is used but when workflows get bigger this becomes an increasingly hard problem. With WF4 I typically solve this by opening the workflow XAML in a text editor and searching the raw XML. The new search capability will let you search through a workflow in the designer, as you really should, just as any other Visual Studio artifact. www.dotnetevents.nl.NET Workflow WF4 Futures dotnetmagfeatures where announced. www.TheProblemSolver.nl

• Updating workflow instances using an update map
  
  One of the really important new features in Windows Workflow Foundation 4.5 is the capability to version workflows and workflow instances. You get to choose what you want to do, either keep running existing instances with their original workflow definition or upgrade them to the latest workflow definition. If you find a bug in your workflow definition the update scenario is probably what you are looking for. In this blog post I am going to explain how to do an upgrade of an existing workflow instance. Make some changes to the workflow definition.
