When a WSDL defines an element that has a minOccurs='0' you get an additional specified flag for that field that indicates if you want to actually send the field. The setter for the field value should also set the specified flag as well, If i've set a value in the field then its because i want to send it. This makes it vastly more natural to work with.

generate a WSDL that contains this complexType definition

<xsd:complexType name="address">
<xsd:sequence>
<xsd:element name="Rating" type="xsd:int" nillable='true' minOccurs='0'/>
</xsd:sequence>
</xsd:complexType>

generate a client side proxy from the WSDL using wsdl.exe

[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://samples.pocketsoap.com/dn2/")]
public class address {

private System.Nullable<int> ratingField;

private bool ratingSpecified;

[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
public System.Nullable<int> Rating {
get {
return this.ratingField;
}
set {
this.ratingField = value;
}
}

[System.Xml.Serialization.XmlIgnoreAttribute()]
public bool RatingSpecified {
get {
return this.ratingSpecified;
}
set {
this.ratingSpecified = value;
}
}
}

The setting for the field value (Rating.set) should also set the ratingSpecified field, e.g.

[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://samples.pocketsoap.com/dn2/")]
public class address {

private System.Nullable<int> ratingField;

private bool ratingSpecified;

[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
public System.Nullable<int> Rating {
get {
return this.ratingField;
}
set {
this.ratingField = value;
RatingSpecified = true;
}
}

[System.Xml.Serialization.XmlIgnoreAttribute()]
public bool RatingSpecified {
get {
return this.ratingSpecified;
}
set {
this.ratingSpecified = value;
}
}
}

Thank you for the suggestion.
This would be nice enhancement, but unfortunately this also is a breaking change: in the previous versions of the .net framework setting value of 'xxx' field did not toggle the xxxSepcified value, so if we change this runtime behavior of some existing applications may change and will require user code change to run the same way as before.
