Is there anyway to change the default JSON serialization/deserialization of DateTime in WCF?
Currently, DateTime are serialized into the /Date(1372252162657+0
One way is to use a message formatter to change the default DataContractSerializer
as described in WCF Extensibility – Message Formatters.
Another option is to write an extension method that loads your object into a stream and then you can apply whatever serializer you want to the object. See the accepted answer for Replace default JSON serializer in WCF 4 to JSON.NET for details on how to do this.
