Question

I have created a web service containing an enum with values as follows

public enum DesignChoice
{            
    DesignerChoice = 1,
    CustomerChoice = 2,
    AdditionalDesign=3,
}

When I add a reference to my client website, enum values are changed as in the following code:

(int)DesignChoice.AdditionalDesign returns 2 but I am expecting it to be 3.

I have tried the serialization attributes [System.Xml.Serialization.XmlTypeAttribute()] out of nowhere but had no luck.

WSDL of the service describes the enum as follows:

 <s:simpleType name="DesignChoice">
        <s:restriction base="s:string">
          <s:enumeration value="DesignerChoice" />
          <s:enumeration value="CustomerChoice" />
          <s:enumeration value="AdditionalDesign" />
        </s:restriction>
      </s:simpleType>

When I press F12 on class name in VS it shows me the following code generated from meta data:

public enum DesignChoice
    {
        DesignerChoice = 0,
        CustomerChoice = 1,
        AdditionalDesign = 2,
    }

I am using Visual Studio 2005 and .NET 2.0.
