Just discovered wcsf...

Relative to xsd.exe, WCSF is vastly superior.

It generates reasonable names

It uses generics.

It has a user interface.

One problem...

constructs using choice like this

  < xs:element name="Amount">
    < xs:complexType>
      < xs:choice>
        < xs:element ref="MassAmount"/>
        < xs:element ref="VolumeAmount"/>
      </xs:choice>
    </xs:complexType>
  </xs:element>

generate crappy C# code like this:

       [System.Xml.Serialization.XmlElementAttribute("MassAmount", typeof(MassAmount))]
       [System.Xml.Serialization.XmlElementAttribute("VolumeAmount", typeof(VolumeAmount))]
       public object Item
       {
           get
           {
               return this.item;
           }
           set
           {
               if ((this.item != value))
               {
                   this.item = value;
               }
           }
       }

Why couldn't that just allow setting one or the other enum?
