Imagine you want to create a library that supports different versions of .NET. Of course there are multiple ways to do this but this is the technique that I have adopted for my CodePlex projects. In this episode I'll show you the sample project I used to test out my targets files and how...
What do you do if you want to store state in an activity? Use a field? Be careful—you can get into trouble. In this episode, I show you the right way to manage state in Workflow Activities using Variable<T>.
In this episode I'll show you our new and improved activities for loading XAML and invoking child workflows. About 6 months ago we did a first release of these activities and the feedback came back with some changes we needed to make. Now you can
Create custom activities with Windows Workflow Foundation is easy, but creating a fully featured activity designer is not quite as easy. In this episode I'll show you the tips and tricks of creating an activity designer to get you up and running quickly.
If you have ever had to try and interop between WCF and other web services stacks like WebLogic , WebSphere Apache or others you know that it can be a painful experience. The WCF team has just published a cool new project that will make your life much easier. On this episode I'm joined b...
How many times have you wanted to send a project to a friend or upload it to a web site like MSDN Code Gallery only to find that your zip file has lots of stuff that you don't need to send in it making the file larger than it needs to be.
Workflow in the cloud... it's like a silver lining just waiting to happen. In this episode I'm joined by Josh Twist Workflow PM who will show you how you can use Workflow in Windows Azure AppFabric.
In this video Steve Danielson, a Programming Writer on the WF team, gives a walkthrough of the WF4 State Machine Getting Started Tutorial from the MSDN documentation.
Wondering how you can secure your Workflow Service? On this episode, I'm joined by Dave Cliffe who explains how Workflow Security works with WCF Security.
In this episode guest host Alan Smith uses the June CTP of Windows Azure AppFabric to create an AppFabric Application that consumes Windows Azure Storage services. A prototype website for an Azure user group will be developed that allows meeting details to be added to Azure Table Storage and photos...
You can store the workflow definitions in Oracle - I'm using Entity Framework 4.1 in my code so you would need a provider that works with Entity Framework.
However, at this time we do not have a Workflow persistence provider for Oracle. You won't need this unless your workflows are long running.
I don't understand your comment about WorkflowServiceHost being limited. It is no different than a WCF ServiceHost. The WCF Service Host will host one service per host. The WF WorkflowServiceHost will host one workflow per host.
However, you can have multiple services and workflow services in you web application. In fact you don't really deal with the WorkflowServiceHost or ServiceHost classes unless you are self-hosting so they are just another part of the infrastructure most of the time.
WCF services have a collection of operations
WF services also have a collection of operations
The main difference is that the WF service can enforce a messaging protocol with certain operations being available only at certain times.
My guess is that if you can build your solution with WCF services you can also build it with workflow services.

Workflow TV - How To Build Workflow Services with a Database Repository
Jun 17, 2011 at 8:57 AMCan provide a web.config with the VirtualPathProvider? I didn't know that.
I wonder if you could support a VirtualDirectory and then place a web.config file in the VirtualDirectory with the config you need if that would work.
It would be worth a try.
