TextFlow is (among other things) a language compiler that generates Windows Workflow programs from a text-based language syntax. like the idea of using a language syntax as yet another means to define workflows. some potential workflow authors will be comfortable neither with code or XAML; the graphical WF designer can help here, but even that requires either Visual Studio, SharePoint Designer (which has a crippled graphical workflow designer, and is SharePoint-specific to boot), or you need to host the WF designer in your own app. There are several reasons for this. There Must Be Some Mistake - Tuesday, March 11, 2008 Presenting. TextFlow! The main idea behind TextFlow is to allowing authoring of WF programs (workflows) via a language syntax, as opposed to (or, eventually, in addition to) using the drag-and-drop designer. The actual generated workflow looks like this: The project includes an authoring tool that let's you toggle between syntax view and workflow view; workflow view is read-only at this point, but I hope to enable bi-directional updating eventually.

There Must Be Some Mistake - Friday, February 29, 2008 | | The Best from There Must Be Some Mistake | MORE | | WF and ASP.NET - A Few Gotchas The default WF scheduler also uses the ThreadPool to execute individual workflows; in combination this would be bad, as it results in 2 ThreadPool threads consumed per web request. What we need is a way to re-use the ASP.NET thread to also execute the workflow. As opposed to the DefaultWorkflowSchedulerService, the manual service grants explicit control over which thread is used to execute a given workflow. there's an extra call to ManualWorkflowSchedulerService.StartWorkflow() that comes after calling Start() on the workflow object itself. inside such workflows. There Must Be Some Mistake - Monday, October 1, 2007 Coming Up For Air As a teaser, think ANTLR + Windows Workflow = "business process authoring for analysts". I understand that "sorry it's been awhile since I posted on my blog" posts are considered bad form by the blogging elite. oh well. started a new job last October, working here. Very interesting company, very interesting work (rules engine technology). but they were quite eager to throw me immediately into the deep end of the pool, so I haven't had time for much of anything since I started. Just now starting to find some energy for endeavors beyond, like this blog. There Must Be Some Mistake - Saturday, February 16, 2008 Getting Closer. Several days ago I mentioned that I'm working on an idea that combines ANTLR and Windows Workflow to demonstrate "business process authoring for analysts". In hindsight, that's a pretty bombastic thing to say. So instead, let's just say that the tool I'm working on could be used by semi-technical folk to author executable business processes. There are many other fine tools in this space; mine incorporates a few (IMHO) clever ideas, but I'm not breaking any monumental new ground. I'm getting closer to having something for public consumption. Oh, and by the way.NET 3.5 There Must Be Some Mistake - Sunday, February 24, 2008 | - Presenting. TextFlow!

| 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.

| The Best from DevelopMentor | MORE | - Rehosting the Workflow Designer in WF4
Beta 2 With Windows Workflow Foundation 3 it was possible to rehost the workflow designer in your own application. With Windows Workflow Foundation 4 live has become much better on the rehosting front In fact it is possible to create the fully functional and useful workflow editor below in about 200 lines of code. And loading or saving a workflow is easy to, all it takes is a Load() and Save() function pointing to a XAML file. One thing that is needed is to register the workflow activity designer metadata. Validating the workflow. null ). {. 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!
