MessageBodyMember namespace overrides DataContract namespace in WSDL

Question

I have following message contract:

[MessageContract(IsWrapped = false)]
public class fooResponse
{
    [MessageBodyMember(Namespace = "http://www.demo.com/serviceSchemaTypes-v1.4/")]
    public commonReturnType fooResponse1 { get; set; }
}

And the commonReturnType is a DataContract below:

[DataContract(Namespace = "http://www.demo.com/serviceSchema-v1.4/")]
public class commonReturnType
{
    [DataMember]
    public returnCode returnCode { get; set; }

    [DataMember]
    public string errorMessage { get; set; }
}

Generated WSDL file overrides namespace of commonReturnType to namespace of public commonReturnType fooResponse1 { get; set; } public commonReturnType fooResponse1 { get; set; } public commonReturnType fooResponse1 { get; set; } . After importing the generated WSDL file into another project, commonReturnType looks like this:

[System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.Tools.ServiceModel.Svcutil", "2.0.2")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://www.demo.com/serviceSchemaTypes-v1.4/")]
public partial class commonReturnType

Here, namespace should be http://www.demo.com/serviceSchema-v1.4/ . Why the namespace is changing here and how can I fix this issue?

Answer 1

The reason for your error is probably that you set this property:

IsWrapped = false

You can refer to the official documentation: Using Message Contracts to make changes.
