How to correctly use XmlWriter.Create()?

I have a method that perfectly serialize data for me:

public static string Serialize(BackgroundJobInfo info)
{
    using (var stringWriter = new StringWriter(CultureInfo.InvariantCulture))
    {
        var writer = new XmlTextWriter(stringWriter);
        var dataContractSerializer = new DataContractSerializer(typeof(BackgroundJobInfo),
                                                                null,
                                                                int.MaxValue,
                                                                true,
                                                                true,
                                                                new MySurrogate());
        dataContractSerializer.WriteObject(writer, info);
        return stringWriter.ToString();
     }
}

But as Microsoft recommend I need to use XmlWriter.

So I change one line:

var writer = XmlWriter.Create(stringWriter);

And everything broken - Serialize() return empty string (instead of string that contains xml)

MySurrogate contains a method

public object GetObjectToSerialize(object obj, Type targetType)
{
    var maskedProperties = obj.GetType().GetProperties();
    var setToNullProperties = maskedProperties.Where(m => m.GetCustomAttributes(typeof(DataMemberAttribute), true).Any() &&
                                                         m.GetCustomAttributes(typeof(DoNotSerializeAttribute), true).Any());
    foreach (var member in setToNullProperties)
    {
        member.SetValue(obj, null, null);
    }
    return obj;
}

You need to call Flush() to force the XmlWriter to actually write the text to the underlying TextWriter.
