[QUOTE="thechad, post: 136016, member: 11382"] Hi All, I have made some progress with the web server and have begun developing some web services to access the MyTV Database using TVDatabase.dll. I have tested some simple web services from python on the Xbox like Echo(), Add(int a, int b) and Split(string SplitString) and all work fine. My next test was to grab a channel list from Mediaportal and this is where I hit a snag. It appears that the Channel class is not serializable as it does not have a parameterless constructor. System.InvalidOperationException: TvDatabase.Channel cannot be serialized because it does not have a parameterless constructor. I have not worked with web services before some I am a bit lost, Is the solution to this to get the MP devs to add a parameterless constructor to MP's classes or can I somehow inherit from Channel my own class like WebChannel and give it a parameterless constructor. I have tried to inherit but am hitting problems with: No overload for method 'Channel' takes '0' arguments Would really appreciate some help on this one. Thanks [/QUOTE]
