This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.

When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF.

I have a Workflow that is using an InfoPath task form. In the "FormEvents_Loading" method event handler I have some code that needs to run each time the form is opened. I recycle the App Pool and open the form the code runs perfectly, but
if I close and try to re-open the form the code is not run at all. I can then recycle the App Pool again and on the next load the code executes just fine. The code that is supposed to be run is a very simple statement to set a field value,
so I don't think it is interfering.
Does anyone know what this might be?
I understand I may be doing this wrong. I read the topic at http://social.msdn.microsoft.com/Forums/en-CA/wfprerelease/thread/a11eb75d-65de-4787-9745-2fd634d0eee9 but I still don't get it, exactly.
I have an application that uses WorkflowApplications to handle the workflows. I have a workflow that contains a one minute Delay activity. When this activity is hit, the workflow Idles, persists (SqlWorkflowDataStore), and unloads. This is all fine. If the app runs for the minute, it will be resumed and will complete.
However, if I stop the app during the minute that it is delayed, and then start it up again at some point later, the workflows do not resume. A little digging shows that WorkflowApplication does not resume automatically, and that I have to do that manually. That's fine. The problem is, I don't know how.
I see there is a WorkflowApplication.LoadRunnableInstance, and I see in the db that there are records in the RunnableInstancesTable table. But when I call LRI, I get back this:
System.Runtime.DurableInstancing.InstancePersistenceCommandException was unhandled Message=In order to match and load a runnable instance in the store, the requesting InstanceOwner must have specified a workflow host type when it was created. To do so, add a key-value pair to the CreateWorkflowOwner
Hi all, i found the below error in event log. How can i fix this issue.
Event ID: 6875 Source: Windows SharePoint Services 3

Please help me out in this issue. Thanks in advance.

I am having this problem that after programmatically loading my workflow from InstanceStore, my variables & input argumwnt where were stored before are unable to deserialized properly.
One of my veriable is a custom object which contians data members of other custom classes. After loading the instance i still have my variable but all of it members were null. Althought all of my custom classes are marked with Serializable Attribute.
What am i missing here?
I use in my ASP.NET MVC application repository pattern and I use in controller for example 3 models:
public class HomepageController : Controller
private IWebsitesRepository _repository_websites = new WebsitesRepository();
private IFirmRepository _repository_firm = new FirmRepository();
private IPhotosRepository _repository_photos = new PhotosRepository();
In WebsiteRepozitory, FirmRepository and PhotosRepository classes I have:
Database1Entities _entities = new Database1Entities();
So I have 3 connections to database ? Is it wrong ? How can I solve it ?
This is quite strange. here is the issue:

When i press the delete button on the pager of my jqgrid, the records are deleted from the database but JqGrid shows some records (4-5). On refreshing the grid, correct numbers of records are shown.
Here is the code:
