Anyone knows how to force a webservice class to be serializable after
regenerating it from wsdl?

I have in the web service:
[Serializable] public class UserInfo
{
public string username;
public string password;
}

But after wsdl I get in the reference.cs:
public class UserInfo {
/// <remarks/>
public string username;
/// <remarks/>
public string password;
}

[Serializable] attribute has no effect in the Asp.Net based webservices
stack. This attribute is used by Remoting technology to serialize types.

I know, I know. But I want to use those classes on the client side and need
them to have the Serializable attribute because I need to throw them to the
ViewState.

Basicaly on the client side I'm doing:

webservice.UserInfo userinfo = new webservice.UserInfo();
ViewState["userinfo"] = userinfo;

But naturally it produces the error that the class is not marked as
Serializable.

Even if I extend the class with something like:

public class ClientSideUserInfo : webservice.UserInfo {};

and then cast it in my calls as in:
webservice.UserInfo userinfo = webservice.getUserInfo(); // function that
returns a webservice.UserInfo object
ViewState["userinfo"] = (ClientSideUserInfo)userinfo;

It will create a runtime error saying its an invalid cast.
