ServiceStack Serializing lists in XML

I have a predefined xml sample which defines the requests and responses, the only part I can't get working with ServiceStack.Text.XmlSerializer is the following snippet, which is basically a list of strings.

<user>
....
    <EmailPreferences> 
        <EmailProgram>Newsletter</EmailProgram> 
        <EmailProgram>Coupons</EmailProgram> 
    </EmailPreferences>

I tried using the example Using Structs to customise JSON, but as the title implies that didn't affect the xml serialisation.

ServiceStack uses .NET's XML DataContractSerializer under the hood. So you can decorate the models with any customizations it support. So to get something like the above you could do:

[CollectionDataContract(Name="EmailPreferences", ItemName="EmailProgram")]
public class EmailPreferences : List<string>
{
    public EmailPreferences() { }
    public EmailPreferences(IEnumerable<string> collection) : base(collection){}
}

Global XML Namespaces

Although you can individually add namespaces to each DataContract a better idea instead is to have all your DTOs share the same namespace, this will prevent the auto-generated and repeating namespaces from appearing in your XML.

As the ResponseStatus DTO is already under http://schemas.servicestack.net/types namespace so if you don't care what your namespace is I would leave it at that.

The easiest way to have all your DataContract's under the same namespace is to put these assembly wide attributes in your AssemblyInfo.cs for each C# namespace your DTOs are in:

[assembly: ContractNamespace("http://schemas.servicestack.net/types",  
    ClrNamespace = "ServiceStack.Examples.ServiceModel.Operations")]
[assembly: ContractNamespace("http://schemas.servicestack.net/types",  
   ClrNamespace = "ServiceStack.Examples.ServiceModel.Types")]
