How to use C# client to consume Django/Python web service (all methods are returning null)?
We faced the similar problem while consuming a web service it was the type of data returned we were getting data in UTF-16 format. 
Please check if you have proper data type in use.
I have a C# command-line client that I'm testing the consumption of SOAP/WSDL via Django/Python/soaplib created WSDL. I've managed to successfully connect to the web service by adding a service reference. I then call one of service's methods, and the service processes the data I send, but it returns null instead of the integer I'm expecting. Any ideas on how to get back something other than a null response? Thanks for any help or suggestions!
