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.

| The Latest from DevelopMentor | MORE | | Tincr and live reloading of CSS/JavaScript in Google Chrome The standard workflow with web development is run the web application, make some changes to your CSS in Visual Studio, flip back to the browser and reload the page to see the effect. Using Tincr with an ASP.NET MVC application is easy. While this works relatively well it can be somewhat slow at times. One improvement is make changes to your CSS in the browser. use Google Chrome as my main browser and it’s CSS and JavaScript viewer is actually an editor so you can make changes there. And if you accidently navigate away or reload the page your changes are gone. Recommended!

| The Best from DevelopMentor | MORE | - 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. The Problem Solver - Wednesday, December 23, 2009 - 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! The Problem Solver - Thursday, November 19, 2009 - 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. The Problem Solver - Wednesday, April 28, 2010 - 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. Tags: NET Workflow WCF WF4 VS2010 Beta2 Note: This blog post is written using the.NET framework 4.0 else. {. Enjoy! The Problem Solver - Monday, December 21, 2009 - Securing a Workflow Service using Windows Identity Foundation
The way security is often still handled these days with each application keeping track of their own users is somewhat dated. Some form of Federated security, where a single separate server is responsible for the security of a whole series of applications, is the way to go. On the internet there are plenty of examples of this with applications using things like OAuth and leaving their security to others. How about securing a workflow service? As a workflow 4 service is just another WCF service securing it is just as easy as the steps below will demonstrate. The Problem Solver - Friday, September 24, 2010 - Workflow 4 and Visual Basic expressions
When using Windows Workflow Foundation 4 you often need to enter expression in some activity property. After all power business users are expected to be able to modify workflows. Right Visual Basic for Applications is their language of choice. Well it turns out workflow is smart enough to realize it can convert the string literal to a Time Span and use this. Tags: NET NetFx3 Workflow VB WF4 VS2010 The new thing is these expressions are all in the Visual Basic dialect regardless of what language you project is in. Weird right? Not very VB like right? Enjoy WF4! The Problem Solver - Monday, October 26, 2009 %>
