workflow-foundation-4

There's not much more to add really than the above question. I have a fairly simple build process template, which has hardly deviated from the default one. I have two custom activities, which by recommendation live in a separate assembly within the same solution. However.... Opening the template takes about two minutes. Changing properties on an activity in the workflow, reordering activities in the workflow, adding activities to the workflow, all take between 30-60 seconds. It's completely unusable at the moment and I'm beginning to regret moving from Cruise Control to TFS for build

I'm using RX extensions and WF4 to create a workflow which reacts to observable messages to progress the workflow. To do this, I bring in an object containing an IObservable (ModuleMessage being my abstract class.) The problem I'm having is that .Subscribe fails to recognize any of its extension methods, namely the one for lambda extpressions/method groups. In the following code, I have references: using System.Activities; using System.Activities.Hosting; using System.Collections.Generic; using System.Reactive.Linq; And also the following line of code: internal void AddModuleCallback(IModule

I am currently saving my .NET FX 4.0.1 StateMachine activity like this: var sb = new StringBuilder(); var xamlWriter = ActivityXamlServices.CreateBuilderWriter( new XamlXmlWriter(new StringWriter(sb), new XamlSchemaContext())); XamlServices.Save(xamlWriter, activityBuilder); return sb.ToString(); This works fine and the generated XAML looks good. Unfortunately, it is invalid. I can read it back in using ActivityXamlServices.Load but when I execute it, it says that it doesn't know the properties defined in the workflow. Opening it in the Visual Studio designer yields the same errors: Compiler

I was trying to find a free and open source BPM tool which is based on asp.net, but unfortunately i fail to find such a tool. But recently I read an article about Windows Workflow Foundation, so does it provide functionality that are similar to open source BPM tools such as Activiti , bonita, Joget, etc. Or Windows Workflow Foundation can not be used to build as full business process workflow as in Activiti and other open source BPM tools. Mike Perrenoud The first thing to remember is that WF is not a BPM tool - but rather a framework that can be leveraged to build a reliable and flexible set

We are in the process of selecting a workflow solution for a company that uses Microsoft products end to end. Given the news on WF4, in that it seems to be essentially a rewrite of previous versions, is it a wise move to back the current version or should we be looking elsewhere? Ie - is the current version so bad that we would not be wise to try and use it? gbanfill Haiving just launched a project which .NET 3.5 and workflow I'd say that the current release of WF is good enough to use and run with. It has helped us to get a product out quickly (we have the usual feature creep and requirements

Related to this question . I understand how to implement versioning of workflows using WorkflowApplication . If you keep the original XAML definition for older versions of your workflow around, you can load them using the right WorkflowApplication constructor. How could you ensure that WorkflowServiceHost uses the correct workflow definition when you want to host your workflows in IIS? There is a WorkflowServiceHost constructor that you can use to load a workflow definition, but when you are hosting inside IIS through a XAMLX file, you do not call WorkflowServiceHost yourself, this is handled

We are evaluating Windows Workflow Foundation 4 to use in MVC 3 based Web Applications. We would like to create flexible order workflows for different projects. Does anybody know good information about the general architecture or hands-on-labs for this kind of application? Some concrete questions would be: how can you activate a specific controller/action from the workflow? what is the best way to communicate between the workflow and the web application (events, wcf services, ...)? This is a nice article on how to start working with WF4 in your ASP.NET MVC app. Integrating a persisted WF4.0
