SharePoint for Developers (WSSv3/MOSS2007)
Day 5 Out-of-the-Box Workflow Capabilities Many companies built custom code to handle common business workflow scenarios around the many document and form libraries introduced in the last version of Windows SharePoint Services. The WSS team realized the business requirement for easily building workflows. We learn to build sophisticated workflows using the out-of-the-box functionality in the new version of SharePoint. We discover how to code more complex custom workflows. We learn to take advantage of the power of VS 2005 to build workflow applications.

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!

Workflows and no persist zones
There are times when a workflow can't be persisted safely using a SqlWorkflowInstanceStore. The reason isn't so much saving the state of a workflow to disk, that could be done at any time, but the result when a workflow would be reloaded from disk in that state. An easy example is a workflow handling a WCF request with a Receive and SendReply activity pair. Suppose you would save the workflow state after the message had been received but before the response had been send. The first action of the reloaded workflow would be to send the response again.

Software Architect Conference 2010
m going to be delivering two sessions on Windows Workflow Foundation 4.0: the first explains the basic architecture and looks at using workflow as a Visual Scripting environment to empower business users. The second looks at building big systems with workflow concentrating on the WCF integration features. I’m speaking at Software Architect 2010 in October. In addition to that I’ll be delivering two all-day workshops with Andy Clymer : Building Applications the.NET 4.0 Way and Moving to the Parallel Mindset with.NET 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. 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. null ). {.

  • Getting started with Windows Workflow Foundation 4
    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 That might be a bit surprising, after all we still have activities and a workflow runtime right? Creating workflows is done by creating a WorkflowInstance object. This object is raises events for that workflow and only for that specific workflow. Select the Workflow node and you will see the four new project types More about the different types in another blog post.

  • 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. In WF4 this central class no longer exists and we manage individual workflows. It basically runs a workflow and prints a message when done: static void Main( string [] args). {. Console.WriteLine( "The workflow has completed." Console.WriteLine( "The workflow has completed." quot; ); }; myInstance.Run(); Console.WriteLine( "Waiting for the workflow to complete." Nice right!

  • Windows Workflow Foundation 4 and persistence
    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. We can attach it to either a WorkflowApplication or a WorkflowServiceHost and persist workflows when we want. This can be used to run only short lived workflows and doesn’t support persistence. var instanceStore = new SqlWorkflowInstanceStore(connStr); WorkflowApplication app = new WorkflowApplication(workflow); app.InstanceStore = instanceStore; app.Run(); Okay its a little more involved then that. Enjoy!

  • Workflow 4 and soap faults
    RC 1 Using the ReceiveAndSendReply activity template and the WorkflowServiceHost it is easy to create a workflow service. Other applications can communicate with the workflow just as if it is a regular WCF service, they never need to know the difference. Throwing a FaultException When a FaultException is thrown in a workflow service pretty much the expected thing is done. But with a workflow service there is no service contract class we can add the attribute to. So how do we specify the fault contract with a workflow service? But what about faults? Enjoy!

  • Workflow 4 Services and duplex communications
    But with a workflow service this doesn’t work because, without the ServiceContract attribute, there is no way to specify the CallbackContract. Yet workflows support duplex communications. Workflow Services and Durable Duplex. Instead of the normal WCF duplex services workflow services use a mechanism that is called durable duplex. Also settings a workflow, and the client, up for durable duplex takes a bit more configuring. Creating the Workflow Service. First step is to create the workflow service. Next we need to update the workflow itself.
