| The Latest from Maurice de Bejeir | 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. 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. The nice thing is you see the effect of your changes immediately making for a much faster feedback loop. How cool is that? Recommended!

The Problem Solver - Saturday, November 17, 2012 Side by side versioning of workflow services 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. In the previous blog post I described how to upgrade existing workflow instances to run with the last version. The basic steps Create your initial workflow definition. Start one or more instances using this workflow definition. Enjoy!

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 | - 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. Tags: NET Workflow WCF WF4 VS2010 data]. data.ToString()]. Enjoy! The Problem Solver - Tuesday, May 18, 2010 - Flowcharts in Workflow 4 and the Switch activity
Flowcharts are a nice addition to Windows Workflow Foundation 4. They allow for a lot of pretty complex behavior that is hard to do in a sequential workflow. In WF 3 we used to model these complex behaviors as state machine workflows. Enter the flowchart in Windows Workflow Foundation 4 One of the good things is that a flowchart is not another workflow type. No it is just another activity to drop in a workflow. So you are free to combine sequential work with a flowchart in one workflow. Tags: NET Workflow WF4 VS2010 So far so good. Enjoy!

The WorkflowApplication is a great way to execute your workflows in process. For example executing a workflow and updating the state of the user interface is much simpler when the WorkflowApplication.Run() doesn’t finish until all work is done. Take this very simple workflow and its execution output. var workflow = new Sequence(). {. Executing the workflow synchronously. Making this workflow execute in a synchronous fashion is easy and requires only a very small change by setting the SynchronizationContext to a custom implementation. Activities = {. The Problem Solver - Friday, January 7, 2011 - 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. {.

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. To start with I created a small workflow service and a simple client application. Tags: NET Workflow WCF WF4 VS2010 WIF 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. try. {. try. {. Enjoy!

| The Latest from DevelopMentor | MORE | | Devweek 2013 Workflow 4.5. Thanks to everyone who attended my sessions at Devweek 2013 – I had a lot of fun delivering them. It was also great to catch up with old friends and make a few new ones. As promised I have uploaded all of my slides and demos to the cloud and they can be downloaded here.

Restore During Build Workflow. There are three differences with the default NuGet workflow: A.nuget folder is added to the solution, which contains NuGet.exe, a config file and a build file. If you’re using the Restore During Build Workflow, then the zip does not need to contain the actual packages I’ve been using NuGet for years, but recently I’ve been playing with around with NuGet to try and explore some of the lesser known features. How does NuGet play with regards to source control? Open the Package Manager Console. Zipping projects. DevelopMentor Courses - Monday, January 21, 2013 Use NuGet package restore to simplify code sharing This whole workflow was introduced for simplifying source code management. Here’s a quick post on how and why you want to consider using NuGet package restore. First, if you’re unfamiliar with NuGet, it’s basically “add reference” to external software projects (typically open source ones such as jQuery, but also for Microsoft ones such as Entity Framework). You definitely need to check out David Ebbo’s post introducing it. NuGet will change the way you develop. Now when using NuGet it maintains a packages folder near your solution file. Michael C.
