endpoint.tv - Service Discovery with WCF

Ron Jacobs — Thu, 14 May 2009 15:51:00 GMT

WCF in .NET 4 includes an implementation of the WS-Discovery protocol. Sounds exciting right? Actually it is very cool because it allows you to build applications and services that can discover other services using UDP multicast messages or via a discovery proxy. In this episode I'll walk through the Service Discovery lab where we build a messenger style application I call "ChatWOW". In this lab you will see how to make your service discoverable and how you can discover other services. Later when Beta 1 is released, you can try it yourself.

Update: The WCF/WF4 Training Kit is now live at http://code.msdn.microsoft.com/wcfwf4 so you can try it yourself.

endpoint.tv Screencast - Declarative XAML Workflows in WF 3.5

Cliff Simpkins — Wed, 11 Mar 2009 15:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to use declarative XAML workflows.

In this screencast, Matt demonstrates how to build and run your workflows in XAML; allowing you to express your workflow completely in this XML-based format. He starts off by creating a new WF workflow using the XAML workflow project file, and walks the viewer through the files that are created by this VS project, and how to remove the code behind (.cs file) so that your workflow project will be based soley on a XAML file to explain it. We then work with the workflow in both the XAML/text editor and the WF designer to add the business logic, modify the .NET application to read in and process the XAML file, and run the workflow.

Along the way, Matt then delves into the created XAML file to examine and explain the structure and used namespaces in that XAML file. Matt also explains the impact of starting XAML only workflows - how and why we need to load the XAML file differently, and some additional exception handling that you should add to handle the runtime exceptions that can come with XAML-only workflows (because the workflow isn't being compiled, the validation is happening at runtime).

endpoint.tv Screencast - Using the Listen Activity in WF 3.5

Cliff Simpkins — Wed, 04 Mar 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to use the listen activity in Windows Workflow Foundation (WF) to listen for multiple events.

Matt starts with a basic sequential workflow console project and a couple custom activities. He then builds out a workflow that waits for input from the user (using a read line activity), and also implements a timeout (using a delay activity) that allows the workflow author to place a limit around how long a WF workflow will wait for input.

Along the way, Matt explains the user how the use of IEvent activity interface allows custom activities to subscribe to events that the listen activity can pass along. Also covered is how to catch exceptions that may arise after using the delay activity to 'timeout' the WF workflow.

For additional information on WF, please check out the WF Dev Center on MSDN and the .NET Endpoint team blog.

endpoint.tv - "Dublin" what is it and why should I care?

Ron Jacobs — Sun, 01 Mar 2009 21:54:00 GMT

"Dublin"? What is it? What is it for? When is it coming?

You may have heard about the exciting new capabilities coming for Windows Server in the area of hosting and managing workflows and services. You might have seen Dan Eshner's talk from PDC2008 here on Channel 9 at http://channel9.msdn.com/pdc2008/BB18/

In this episode of endpoint.tv I caught up with Dan and Ford McKinstry to get to the bottom of the "Dublin" mystery.

endpoint.tv Screencast - Fault Handling in WF

Cliff Simpkins — Wed, 25 Feb 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how fault handling works in Windows Workflow Foundation (WF) 3.5.

In this screencast, Matt starts with an existing workflow application (a console application), and adds a custom activity that throws an exception. Initially, Matt demonstrates how this is thrown and it's effect on the workflow instance. He then demonstrates how to add fault handlers into a WF sequence to handle faults in a more graceful manner - very similar to the C# try/catch pattern. Matt also explains how exceptions 'bubble up' within a WF workflow - very similar to standard .NET applications.

endpoint.tv Screencast - Working with Transactions in WF

Cliff Simpkins — Wed, 04 Feb 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to work with Windows Workflow Foundation (WF) transactions, from the simple use case of scoping activities to participate in a transaction to the more advanced scenario of queue up work to participate in a transaction from an activity or the WF host application.

In this screencast, Matt demonstrates how to use the transaction scope WF activity and set the necessary properties on the activity. He then dives into how transactions work in WF to guarantee consistency in the activities, the WF workflow, and the overall transaction that WF is participating in. Along the way, Matt uses console outputs to demonstrate the execution order of activites and the transaction to visually demonstrate what the runtime is actually doing once you execute the code.

endpoint.tv Screencast - Using the WF Replicator Activity

Cliff Simpkins — Wed, 28 Jan 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to using the WF replicator activity to add more advanced flow control capabilities to your WF workflows.

In this screencast, Matt introduces the replicator activity, which allows you to implement ForEach-like semantics on workflow data. He adds the replicator to an existing workflow, binds the activity to the incoming data, and demonstrates how the replicator activity runs child activities. For this screencast, Matt uses an example sending e-mail notifications to persons in a data list.

While explaining how the replicator works, Matt explains a few aspects of the replicator activity: (a) how to interact with child activities within the replicators events, (b) how to set the activity execution type to have control over how the iterations are executed (i.e., sequence or parallel), and (c) how to use conditions to set a replicator stopping point.
