I need to add Workflows to an existing solution, which already contains a class library and a web site. If I add the workflows to the class library, where they fit logically, I have no designer support. If I create them in a separate project, I tend to have circular dependencies because my domain objects run the workflows and the workf...
I am developing a State Machine Workflow using C# and WF in visual studio 2008. On one of my states I need to wait for multiple events to happen until the workflow can transition to the next state. As an example think of a unanimous voting scenario. I cannot find a way to do this. Does anyone have a solution or workaround for this pr...

I am interested in learning some BPM software. One of such software is ProcessMaker. But the problem with this is that it is lacking of documentation.

A state machine workflow has the StateMachineWorkflowInstance class that you can use to inspect the current state of the workflow, get legal transitions, etc...

Hi, I have a simple workflow with the HandleExternalEventAcitivity. The workflow ought to wait for the user to take an action, which in turn raises an event that the workflow activity handles. Since it is an ASP.NET app, I am using the ManualWorkflowSchedulerService to have my workflow run synchronously. However with the ManualWorkflow...

I am trying to figure out the internals of the windows workflow foundation. So, we have some software components and we intertwine them in the form of a workflow be it a condition based sequential workflow or a state machine workflow. Now, I am thinking (I may be wrong here) that doesnt the same apply to IoC + Dependency Injection (via U...
We're currently building a system that abstracts all kinds of technical details about web services from some other systems. It's a bit like an Enterprise Bus, but it does a little more. We decided to use Windows Workflow to handle the requests. As soon as we figure out what kind of action is requested, we'll start a workflow that is spe...
Our workflow in Workflow Foundation used to call ASMX web services using the InvokeWebService activity, which has a property SessionId to correlate multiple activities in the same session (by sending the ASP.NET session cookie on every request). It worked. Now we have switched to WCF web service interface, and we have changed our workfl...
Hello! I am trying to use Windows Workflow and have a model that looks similar to the image in the link below: Workflow screen shot After each of the Send Activities (GetSomthing, GetSomthingElse, GetSomeMoreStuff) the same custom acitvity is being called (LogSomthingBadHappened). Whilst it might not look so bad in this picture in my re...

Granted it was a fairly technical question that contained terms like ManualWorkflowSchedulerService, HandleExtrenalEvent, etc... it got about 15 views over the course of 20 days. While it is most likely a matter of me not asking the question t...
I am writing a custom Windows Workflow Foundation activity, that starts some process asynchronously, and then should wake up when an async event arrives. All the samples I’ve found (e.g. this one by Kirk Evans) involve a custom workflow service, that does most of the work, and then posts an event to the activity-created queue. The main...
In workflowRuntime_WorkflowUnloaded and Loaded etc.. the only thing I can get which is pretty useless is the workflowinstanceId. I want to be able to access some DPs that are on the root activity, whenever I do a GetWorkFlowDefintion() and cast to root activity, all the property that I've passed in are all null.. ...
I've got common code that can run in a number of execution enviroments - within IIS, within a WCF service, in a stand-alone application, or in a Windows Workflow instance. But what is the best way to check whether the code is running inside a Workflow? For the moment, I've been looking for WorkflowEnvironment.WorkflowInstanceID and catc...
