A property with the name 'httpRequest' is not present

Question

I've ran into an interesting problem using the Azure Service Management API. Specifically, when I try any operation, I get a "Server Error in '/' Application. A property with the name 'httpRequest' is not present. ".

This only happens in one project and I can't reproduce it with creating other projects.

I've tried reading Fusion logs, because I've suspected there's a problem with assembly versions, but it turns out not to be the case. I also tried readding references, which also didn't work.

I'm stuck - does anybody have a clue?

<InnerException i:nil="true"></InnerException>
    <Message>A property with the name 'httpRequest' is not present.</Message>

The solution is described in detail here. But you need a nudge in the right direction, which is nutoriously difficult to find. We've had the same issue a while ago so I've written a blog post about httpRequest not being present exception (WCF).

To summarize, wrap your call to the code in:

    using (new OperationContextScope((IContextChannel)channel))
    {
       // ... my code
    }
