Hello Experts ,
I am creating a webmethod which takes input custom object . I have given a simplifed sample of WSDL where I am facing Problem.My WSDL gets all classes and types (Filter1,Filter2) in it but When I add a web reference from visual Studio it only gives me Filter2 and No Filter1 :(
But If I use WebService studio to generate request It does Filter1 and Filter2 too.
I have attached my class file to for request.

Use XMLInclude in your service, and include Filter1
Where the method uses Filter1 just set a
[XmlInclude(typeof(Filter1))]

Note: "Serializable" means nothing in XML serializable context of web services. Indeed, including filter1 and 2 does nothing as long as they are in the same assembly and namespace with the param class.
I'm not sure why do you (XML)ignore the properties and expose the fields... Usually the other way is suitable.

I think that if you would simply create the classes with no XML attributes at all, and with private fields wrapped in public properties, that would simply work with no problems.
