I am having issues with NSB reverting to the Xml Serializer for no apparent reason which obvisouly causes an error when trying to deserialize the message. Below is an excerpt from the log, as you can see some come through from the same source as Json and then all of a sudden XML!

Path '', line 0, position 0. at Newtonsoft.Json.JsonTextReader.ParseValue()
Here is the configuration.
public static EndpointConfiguration ConfigureSerialization(this EndpointConfiguration endpointConfiguration)
{
var serialization = endpointConfiguration.UseSerialization<NewtonsoftSerializer>();
serialization.ContentTypeKey("NewtonsoftJson");
var settings = new JsonSerializerSettings
{
TypeNameHandling = TypeNameHandling.Auto,
Converters =
{
new IsoDateTimeConverter
{
DateTimeStyles = DateTimeStyles.RoundtripKind
}
}
};
serialization.Settings(settings);
endpointConfiguration.RegisterMessageMutator(new MessageBodyWriter());
var externalNewtonsoftJson = endpointConfiguration.AddDeserializer<NewtonsoftSerializer>();
externalNewtonsoftJson.ContentTypeKey("NewtonsoftJson");
return endpointConfiguration;
}
Any idea why this might be happening and how I can stop this from occurring?
P.S. at the moment I am using the LearningTransport.
