Today on endpoint.tv I showed how to create a workflow service that can do background work on a scheduled basis (The sample code is posted here ). In the example I showed a web UI that allows you to start the job by clicking on a submit button. Somebody...

The voting on our site What do you want to see on endpoint.tv is moving along nicely.  Yes we are going to do something about OAuth with the HttpClient but today I want to think about the #2 issue which is versioning with workflows.  This post...

This morning I awoke to a bright sunny day and thought to myself… What shall I do today? Unlike most people I have a great deal of freedom to be as creative as possible at helping people to build great applications with .NET using WCF, WF4 and...

Today I’m happy to announce the availability of a new Feature Builder based template for Windows Server AppFabric and WCF Data Services. This template is an evolution of the previous AppFabric-enabled WCF Data Service (C#) template. WCF Data Services...

You may have noticed that WorkflowServices have two ways of operating.  One way is to pass message content and the other way is to use message parameters.  I have always used message content because it seemed like the easiest thing to do. Download...

One thing I have not tackled until today was how to test a Workflow Service in a .xamlx file.  When I started out this morning working on it I realized that there isn’t a great deal of information about how to do this available anywhere. Update 7...

Recently I was doing a review of some .NET 3.5 WCF REST code based on the REST Starter Kit to see what it would take to move it to .NET 4. The more I looked at the code and thought about it deeply I realized that the mechanics of exposing a service over...

A couple of weeks ago I ran across a very interesting tool called Feature Builder .  As I watched the videos about this tool I realized that it represented an opportunity to deliver Hands on Labs (along with other interesting things) directly inside...

Lately on http://endpoint.tv we have been doing a series called WF4 Activities Best Practices with Leon Welicki. Many of you wrote in asking for the sample code so I’ve published on MSDN Code Gallery - WF4 Activity Best Practices Sample . Be sure...

This morning I stumbled across something so cool… I had no idea it existed (I know some of you are saying… “What he didn’t know about this?) How many times have you wanted to debug right into the source of .NET?  The feature is there, just turn it...

Most of the time I write simple apps that run in the local ASP.NET development server. I noticed when I started working with IIS more because of Windows Server AppFabric that my routes were not working when the web application is deployed in IIS. For...

After working out how to do the right thing when using WCF Data Services with Windows Server AppFabric I’ve now created a template you can use directly from Visual Studio. The templates are available from Visual Studio Gallery or directly from within...

If there is one thing I hear from people over and over again it is this. Please make WCF simpler, easier to understand and use. I totally agree with this sentiment. In fact, in .NET 4 we made it much easier but we still have a long way to go. Once in...

In this episode, Dave Cliffe, Program Manager for Workflow Services, describes the architecture of the Workflow Services infrastructure. For more information, see the Workflow Foundation developer center on MSDN .

This morning I was refactoring some code and I decided to create a partial class with an overloaded constructor. When I did this, suddenly everything quit working. My tests were failing as though the workflow didn’t even run but no exceptions were...

If you want to assign a value to an OutArgument in your workflow here is something you need to keep in mind. If your OutArgument is something simple like a value type or a string you can simply write to it directly If your OutArgument is something more...
