Web API XML Serialization of DateTimeOffset in ISO 8601 format
Web API 2 serialize DateTimeOffset as two different values:
It should be serialized as a singlue value and in ISO 8601 format just like JsonMediaTypeFormatter does. There's a work around to have string property for every datetimeoffset property that you have in your model and would like to have as single value and in ISO 8601 format. It would be good if it is out of box support just like JsonMediaTypeFormatter.
