Inefficient serialization of message body for transport operations stored in OutboxRecord.TransportOperations serialized by DataContractJsonSerializer.

The DataContractJsonSerializer serialized each byte as a text int value part of a json array:

"<Message>k__BackingField": [
    60,
    63,
    120,
    109
    //..
],
