  • Welcome to Stack Overflow. Please take the time to format your post as readably as possible, and provide more information. See codeblog.jonskeet.uk/2010/08/29/writing-the-perfect-question for advice on writing questions. At the moment your question is hard to read and lacks a lot of important information - such as service you're calling, the stack trace, and whether you have any way of telling whether a request is reaching the service at all.
