.NET WCF Can't Decode "Chunked" response.
I am calling an axis web service from WCF. The request works just fine but I get back null values. Using Fiddler I was able to determine that the response is coming base as Transfer-Encoding: chunked. This means that there are control characters in in the response BEFORE the xml. WCF does NOT throw an error. It just moves on and the...
