Question

I am building a webservice using RESTful approach and am using WCF WebHttp API (.NET v4).
To satisfy some legacy functionality I need to accept raw XML message via POST and process it..For example one of my methods looks like:

[WebInvoke(UriTemplate = "Hello", Method = "POST")]
public Message ProcessMessage(string xmlMessage)
{
    if (String.IsNullOrWhiteSpace(xmlMessage))
    {
        return WebOperationContext.Current.CreateXmlResponse(ProcessingFailedReply);
    }
    var message = XElement.Parse(xmlMessage);
    return WebOperationContext.Current.CreateXmlResponse(ProcessingSuccessfullReply);
}

However, every time I try to POST some xml to “/Hello” I get a message that the format is invalid and it wants specifically encoded string. I guess the API is using standard schema to automatically serialize xmlMessage. When I visit the help (“/help”) I am given an example format for my xmlMessage:

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">String content</string>

How do I allow and process the POSTed request as raw in this scenario?
I looked over the API and the only relevant class (WebOperationContext.Current.IncommingRequest) does not have any methods to retrieve raw message…

Thanks

Create an input parameter of type XElement and you can query the XML any way you want.
