I’ve had a couple of people ask me about this in the past week, so I’m thinking this may be a common problem some of you are seeing. I also see two of my colleagues have blogged about it, so I thought I’d help spread the word.
The problem is you install the Azure AppFabric SDK, but the Service Bus bindings we all know and love are not visible. The cause is .NET 4.0 has its own machine.config and the SDK installer does not make the appropriate entries. This will be fixed in the next coming-soon release of the AppFabric SDK.
In the interim, you can read Kent Weare’s post here, and Wade Wegner’s post here to get past this.
