Soap Encoding Problem with Framework v1.1

[Paul C]

Hi,

I have an interesting problem with my RPC encoded webservices. When I
upgrade to Framework 1.1, I get the following error when calling my web
methods.

[Server was unable to process request. --> File or assembly name
kmcuficw.dll, or one of its dependencies, was not found.]

After a bit (make that quite a bit) of investigation I discovered that the
problem only occurs when the SOAP message style is rpc/encoded. (ie using
the [System.Web.Serv ices.Protocols. SoapRpcService] attribute). After
playing around a little more, I then discovered that the problem only occurs
when I have an optional value type defined in my schema.

For example.

<xs:element name="CountryID " type="xs:int" minOccurs="0" maxOccurs="1" />

autogenerated class


[System.Xml.Seri alization.XmlTy peAttribute(Nam espace="http://tempuri.org/MyCountries.xsd ")]
public class Country {

/// <remarks/>
public int CountryID;

/// <remarks/>
[System.Xml.Seri alization.XmlIg noreAttribute()]
public bool CountryIDSpecif ied;

/// <remarks/>
public string Name;
}



To summarise everything is fine running under v1 of the framework. When
running under framework 1.1 everything works when I either a) remove the
[System.Web.Serv ices.Protocols. SoapRpcService] attribute.

b) leave the [System.Web.Serv ices.Protocols. SoapRpcService] attribute as is
but do not use optional fields.

None of these options are satisfactory as this is a production environment
and my clients wont be happy if I change the WSDL.

Any help on this will be greatly appreciated.

Kind Regards
Paul
