| The Best from DevelopMentor | MORE | - 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. link]. The Problem Solver - Wednesday, April 28, 2010 - Hiding the XAMLX from a workflow service
In Windows Workflow Foundation 4 it’s easy to create a workflow and expose it as a WCF service. But one thing is that it exposes a XAMLX endpoint to each client can see the service actually implemented as a workflow service instead of a regular service. One way to hide that is to use a regular SVC file as the implementation and point that to a workflow using the WorkflowServiceHostFactory. First we need to use a regular workflow instead of a workflow service. Next we add a WCF Service named Workflow1.svc. data]. data.ToString()]. Enjoy!

In the previous blog posts, here , here and here , I demonstrated how to use WCF from WF4. This same some more about sending multiple messages to the same workflow, AKA Workflow Correlation. One of the ugly parts of Windows Workflow Foundation 3 was the message correlation part when you used WCF to send multiple messages to the same workflow. This guid was the workflow instance ID but having to use that on the client means the client had to be very aware of the server technology used, something that goes against the principals of WCF. The Problem Solver - Wednesday, September 2, 2009 - Versioning long running Workflow Services in WF4
One of the problems with the current version of Windows Workflow Foundation is how to handle different versions of your workflows. With short running workflows this is no big deal, workflows do whatever they are supposed to do and finish, and you can deploy a newer updated version of your XAMLX files whenever you want. However as soon as we get into long running workflows and the SQL Workflow Instance Store things get quite a bit more complicated. It uses this data to differentiate between different workflow service definition. Unfortunately not. The Problem Solver - Thursday, November 4, 2010 - Flowing transaction into a workflow using WF4
Beta 2 One of the things that wasn’t possible in Windows Workflow Foundation 3 was flowing transaction over a WCF service request into a workflow. Fortunately that is one the problems that Windows Workflow Foundation 4 solves for us. In WF4 we can use the ReceiveAndSendreply template to configure a workflow as a service and accept WCF calls. If we want to use transactions we need to add the TransactedReceiveScope to the workflow. First of all we need a WCF binding that can flow transactions. public static string GetReport(). {. else. {. The Problem Solver - Monday, December 21, 2009 - More Workflow 4 Services and duplex communications
Yesterday I posted a long blog post explaining how to do duplex communications in a Workflow service. Its a long story but the most important points where that workflow services don’t support the same style duplex communication as WCF with the callback channel defined in the ServiceContract but rather something that is called durable duplex where the callback contract is independent and the client has to create a ServiceHost and act as a full-blown WCF service. As WCF callbacks are not supported using a ServiceHost on the client is unavoidable. Conclusion. The Problem Solver - Tuesday, May 4, 2010 %>
