Hosting a Workflow in a Local Executable using Workflow Services Part I

keydet — Thu, 17 Apr 2008 23:40:57 GMT

When the Windows Workflow Foundation (WF) was first introduced in the .NET Framework 3.0, the only way to host a workflow in a client application was to use the WorkflowRuntime class programmatically, start the runtime, and create/start an instance of a workflow. Furthermore, if you wanted to communicate between the client code and the workflow logic, you needed to ues a ExternalDataExchangeService. This required a fair amount coding effort to get even the simplest of workflows up and running. The .NET Framework 3.5 introduced Workflow Services which are Windows Communication Foundation (WCF) Services authored as workflows. Workflow Services give you a new way to accomplish this scenario using a much simpler, cleaner, and arguably more elegant approach. In this three part screencast, I show you how to improve on the more manual hosting + ExternalDataExchangeServices approach by hosting a workflow in a client executable using Workflow Service.

Create a Sequential Workflow tutorial so we can compare the two approaches. The application explicitly hosts the WorkflowRuntime & uses ExternalDataExchangeService

Part III - Walking through my rewrite of the SimpleExpenseReport application using Workflow Services.

Exposing/Consuming RSS/ATOM using WCF 3.5 & Silverlight 2

keydet — Fri, 11 Apr 2008 20:40:44 GMT

Marc Schweigert shows you how easy it is to expose RSS and Atom feeds using the new Web Programming Model (REST) features, classes in the new System.ServiceModel.Syndication namespace, and LINQ to SQL in the .NET Framework 3.5. Then, you will see how you can use classes from the System.ServiceModel.Syndication namespace to consume RSS and Atom feeds using Silverlight 2.

Silverlight 2 DIGG Sample Part I

keydet — Fri, 04 Apr 2008 01:26:28 GMT

Scott Guthrie has a great eight part series titled First Look at Silverlight 2 where he walks you through building a Silverlight 2 sample app from scratch. The walkthrough highlights almost all of the key features of Silverlight 2 Beta 1. The walkthrough is so comprehensive that I have been using a slightly modified version of it for my Silverlight 2 presentations. Since I am a big fan of seeing vs. reading, I asked Scott if it would be ok if I turned his written walkthrough into a video walkthrough delivered as a Channel 9 screencast. Scott gave me the thumbs up so I put together what turned out to be a three part screencast. Here are the direct links for each part:

JavaScript Intellisense for the Virtual Earth Map Control

keydet — Tue, 26 Feb 2008 16:02:04 GMT

UPDATE: Folks are experiencing issues sending to the contribution email address. This has been fixed. Details here.

Have you ever wished you could get JavaScript Intellisense for the Virtual Earth Map Control in Visual Studio 2008? I have, so I came up with a solution and started a codeplex project! This screencast explains the solution.

The project is not finished. I need people to volunteer to contribute so we can release full intellisense for the Virtual Earth Map Control 6.0. Instructions for people who want to contribute are in the screencast. The more people willing to contribute, the faster we make this available for everyone!

If you want to keep up with what's going on with the project, subscribe to my RSS feed from http://devkeydet.com. The codeplex project is http://codeplex.com/vejs.

Easy Multithreaded Programming Using BackgroundWorker

keydet — Tue, 24 Jan 2006 22:54:22 GMT

Here's a quote from Chapter 6: Using Multiple Threads of the Smart Client Architecture and Design Guide:

"To maximize the responsiveness of your smart client applications, you need to carefully consider how and when to use multiple threads. Threads can significantly improve the usability and performance of your application, but they require very careful consideration when you determine how they will interact with the user interface."

.NET Framework 2.0 and the BackgroundWorker component to the rescue! Marc Schweigert, Federal Developer Evangelist, shows you how easy it is to build a responsive multithreaded Smart Client application with Windows Forms 2.0 & the BackgroundWorker component.
