Using the WCF OperationContext from a Receive activity
The WF4 Receive activity shields you from a lot of the WCF pipeline. Normally that is a good thing but there are occasions where you want to know more about the incoming WCF request. Normally you can use the WCF OperationContext.Current to get at this information but with a workflow service this doesn...

Converting a C# workflow into XAML
A interesting question that came up last week was how to convert workflows defined in C# to XAML.

Workflows and no persist zones
There are times when a workflow can’t be persisted safely using a SqlWorkflowInstanceStore. The reason isn’t so much saving the state of a workflow to disk, that could be done at any time, but the result when a workflow would be reloaded from disk in that state. An easy example is a workflow handling...

Breakpoints not being hit in Windows Workflow 4?
Just a quick one. If you set breakpoints in a windows workflow but during debug it skips right past them it might mean things have not have been reflected on the underlying XAML file. So make a small change to the workflow surface, save it, build the project and try again. I found the answer [...]

Hosting workflow services in Windows Azure
Since the latest release of the Windows Azure Development Kit (June), Azure provides support for .NET 4 applications, which is a real important step from the point of adoption, I believe.

Using the LOB Activity in AppFabric workflows
1. Right-clicking the workflow project, will show the Add Adapter Service Reference… menu item. 2. This shows the familiar Add Adapter Service Reference dialog box. (Don’t you all agree this tool still looks too much of ‘Form1/Button1’ app? J ). After selecting the sqlBinding...

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...

Workflow 4 Services and duplex communications
There are quite a a few cases where it is useful to have a duplex communications. An obvious candidate is allowing a service to notify the user interface application of the progress so the user knows what is happening.

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...
