Serializing List to xml

Serializing object with no namespaces using DataContractSerializer

When I'm serializing object of this class:

[DataContract]
internal class Settings
{
    [DataMember]
    public List<string> AllowedEmails { get; set; }
}

I've got this XML as output:

<?xml version="1.0" encoding="utf-8"?>
<Settings xmlns="http://schemas.datacontract.org/2004/07/Commands.Settings">
    <AllowedEmails xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
        <d2p1:string>asdsada</d2p1:string>
        <d2p1:string>asdsada</d2p1:string>
    </AllowedEmails>
</Settings>

Is there a way to get rid of namespaces xmlns="http://schemas.datacontract.org/2004/07/Commands.Settings" and xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"?

I know I can remove d2p1 namespace by doing this:

public Settings()
{
    [DataMember]
    public AllowedEmails AllowedEmails { get; set; }
}


[CollectionDataContract]
public class AllowedEmails : List<string>
{
    public AllowedEmails()
    {
    }
}

But may be there is more elegant solution?
