After trying different things I accidentally happened upon the solution. I set the XmlElementAttribute.IsNullable
to true like the previous answer suggested.
[System.Xml.Serialization.XmlElementAttribute(ElementName = "Confirm", IsNullable=true)]
public ConfirmType Confirm
{
get
{
return this.confirmField;
}
set
{
this.confirmField = value;
this.RaisePropertyChanged("Confirm");
}
}
Then when setting the confirm type in the code I used the default constructor instead of setting Confirm to null.
retval.ConfirmBODDataArea.Confirm = new ConfirmType();
This serialized as <star:Confirm/>
