Aegis databinding -- Duplicate C# proxy classes generated for Java classes

[skuramshin]

Hi All. My question is about integration between CXF-based Java web service
and a C# .NET client.

Service: CXF 2.2.3 with Aegis databinding
Client: C#, .NET 3.5 SP1

For some reason Visual Studio generates two C# proxy enums for each Java
enum. The generated C# classes do not compile. I'm using "Java first"
approach, so the WSDL is generated by CXF.

For example, this Java enum:

public enum SqlDialect {
    GENERIC, SYBASE, SQL_SERVER, ORACLE;
}

Produces this WSDL:

<xsd:simpleType name="SqlDialect">
    <xsd:restriction base="xsd:string">
        <xsd:enumeration value="GENERIC" />
        <xsd:enumeration value="SYBASE" />
        <xsd:enumeration value="SQL_SERVER" />
        <xsd:enumeration value="ORACLE" />
    </xsd:restriction>
</xsd:simpleType>

For this WSDL Visual Studio generates two partial C# classes (generated
comments removed):

   
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization",
"3.0.0.0")]
    [System.Runtime.Serialization.DataContractAttribute(Name="SqlDialect",
Namespace="http://datasource.view.model.archibus.com";)]
    public enum SqlDialect : int {
        
        [System.Runtime.Serialization.EnumMemberAttribute()]
        GENERIC = 0,
        
        [System.Runtime.Serialization.EnumMemberAttribute()]
        SYBASE = 1,
        
        [System.Runtime.Serialization.EnumMemberAttribute()]
        SQL_SERVER = 2,
        
        [System.Runtime.Serialization.EnumMemberAttribute()]
        ORACLE = 3,
    }
...
    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml",
"2.0.50727.3082")]
    [System.SerializableAttribute()]
   
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://datasource.view.model.archibus.com";)]
    public enum SqlDialect {
        GENERIC,
        SYBASE,
        SQL_SERVER,
        ORACLE,
    }

The resulting C# code does not compile:

    The namespace 'xxx' already contains a definition for 'SqlDialect'

This issue does not happen when the default CXF databinding is used instead
of Aegis. In that case, only the second C# enum is generated.

I will appreciate any ideas...
