Using WF4 bookmarks with IWorkflowInstanceExtension
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? So what about using a WorkflowInvoker or a WorkflowServiceHost? Neither the WorkflowInvoker not the WorkflowServiceHost contain a ResumeBookmark function so how do we resume a bookmark using either of those execution hosts?

Bookmarked Activities in WF4
Beta 2 Windows Workflow Foundation 4 introduces the concept of bookmarks to temporarily pause activities. The result is that the workflow runtime doesn’t consider an activity to be finished until all its bookmarks are either resumed or removed. That last statement isn’t completely true though as it is only the case when the optional BookmarkOptions aren’t specified or specified as None. Running the workflow and resuming a bookmark is easy when using a Note: This blog post is written using the .NET NET framework 4.0

  • 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. But possible is about all there was to say about it as it was pretty hard to do anything beyond the basics. 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.

  • Windows Workflow Foundation 4 and persistence
    The whole persistence model has changed quite a but for WF4. The persistence class out of the box is called SqlWorkflowInstanceStore and as the name suggests it saves workflow data in either SQL Server 2005 or 2008. It is based on the InstanceStore class to if you prefer some other store all you need to do is subclass the InstanceStore and create your own. So what can we do with the SqlWorkflowInstanceStore? We can attach it to either a WorkflowApplication or a WorkflowServiceHost and persist workflows when we want. Notice I left out the WorkflowInvoker. This can

  • TryCatch activity in WF4
    I can’t say I am a fan of the way the TryCatch activity is implemented in Windows Workflow Foundation 4. For starters there is a Finally block where you can add some activities you want to execute. This means that an exception that is unhandled which bubbles terminating the workflow up will not cause the finally block to execute unless the host application forces it to do so by returning UnhandledExceptionAction.Cancel from the OnUnhandledException instead of UnhandledExceptionAction.Terminate (the default). Sounds nice and very much like the try/catch/finally code construct we have in C# or Visual Basic.

  • 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 “ http://tempuri.org ”. I also added a WF4 client that called the service and received a response.

  • Combining WCF and WF4
    There are several ways to use WCF in combination with Windows Workflow Foundation 4. The two can be combined inside of a XAMLX file as Ron Jacobs describes here . Another option is using the WF4 Receive and SendReply activities and hosting the workflow yourself using a WorkflowServiceHost. When I was trying to get things working using a declarative workflow and the designer Visual Studio 2010 would keep in locking up so all workflows in this example will be coded using C#. This is quite a useful option but, at least at the moment, not quite straightforward.

  • What does Windows Workflow Foundation 4 mean for existing workflow developers?
    The question of what Windows Workflow Foundation version 4 means for developers currently developing using WF recently came up. In WF 3 there was a choice between state machine and sequential workflows. That said, a number of state machine workflows could very well be done using a flow chart. As far as backward compatibility the story is a bit more complicated. As I mentioned before WF 4 is a complete rewrite and doesn’t use any of the existing WF 3 classes. The design of WF 4 is even quite different from the design of WF 3. So are WF 3 developers completely left
