| The Best from DevelopMentor | MORE | - 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 - Data and Windows Workflow Foundation 4
One thing that has completely changed in Windows Workflow Foundation is the way we work with data in a workflow. Dependency properties left the way data was stored to be handled by the workflow runtime but in our program we could use them just like any other property. The actual data is stored somewhere inside of the workflow using a LocationEnvironment. To store some data inside of your workflow we need to add a Variable to the workflow or one of the nested activities. Creating the workflow using code. In WF 4 this has all changed! The Problem Solver - Monday, July 20, 2009 - What's New in Windows Workflow Foundation in.NET 4.5 (part 1)
Search Searching through workflows is another big one. With small workflows it is quite easy to see where a variable is used but when workflows get bigger this becomes an increasingly hard problem. With WF4 I typically solve this by opening the workflow XAML in a text editor and searching the raw XML. The new search capability will let you search through a workflow in the designer, as you really should, just as any other Visual Studio artifact. www.dotnetevents.nl.NET Workflow WF4 Futures dotnetmagfeatures where announced. Auto surround with a Sequence. The Problem Solver - Tuesday, September 27, 2011 - Windows Workflow Foundation futures and database access
Ron Jacobs showed a number of really cool new workflow features we can be expecting in the next version of Windows Workflow Foundation during the last PDC in Redmond and Tech-Ed Europe in Berlin. One of the new features he demonstrated where the activities we can use to load data from a SQL server database into our workflow. Why don’t I like the new database activities With the new ExecuteSqlQuery we are back to typing in a literal SQL string to be executed on the server and the related connection string directly into a workflow. The Problem Solver - Saturday, November 20, 2010 - Activity correlation in Windows Workflow Foundation 4
There are two types of correlation to think about in Windows Workflow Foundation: Message correlation Basically sending multiple requests to the same workflow. However sometimes we might need to do so ourselves because we create a workflow in a different way, like using regular code. How much varies and depends on both the workflow and the hosting environment we use. The obvious one is using the WorkflowApplication or WorkflowInvoker to run our workflows. Tags: NET Workflow WCF WF4 VS2010 Think about the Send and ReceiveReply activities. The Problem Solver - Wednesday, December 2, 2009 - What's New in Windows Workflow Foundation in.NET 4.5 (part 3)
This is the 3rd post about what is new with Windows Workflow Foundation in.NET 4.5 This 3rd post is about one of the biggest missing pieces which is versioning workflows. To understand why this is so painful at the moment it is important to remember that workflow instances often run for a long time. Right not with WF4 you can’t change the definition of a workflow instance that is running even when it is persisted to disk. Doing so will result in any number of weird exceptions when the workflow tries to resume. Enjoy! www.TheProblemSolver.nl The Problem Solver - Tuesday, October 11, 2011 - Workflow parameters in Window Workflow Foundation 4
Creating parameters for a workflow is quite easy to do in WF 4. Just open the arguments tab in the workflow and add each input or output parameter you need and the required type. Now in WF 3 passing data to a workflow was done using a Dictionary to specify the input. Every time you create an in or out argument the workflow will also get a corresponding public property. Tags: Workflow WF4 VS2010 This is very flexible but also very brittle as it is all magic of key names matching property names. This approach still works as the following code demonstrates.
