Description Peter Hagen 2016-02-26 12:17:52 UTC
Mono throws an exception when deserialising a json string with a "/date(...)/" value in it. .Net doesn't do this. I would except the serialiser to skip this value. 

Way to reproduce in csharp shell:

var ser = new System.Web.Script.Serialization.JavaScriptSerializer();
ser.DeserializeObject ("{\"Id\":33,\"Label\":\"Fire Safety Manager\",\"FkArticleGroup\":\"11\",\"FkArticleType\":\"1\",\"FkBvoLocation\":\"2\",\"SubscriptionsMax\":\"16\",\"NrOfDays\":6,\"DateCreated\":\"/Date(1452085898000+0100)/\",\"DateModified\":\"/Date(1454506875000+0100)/\",\"SesReq\":\"h7GkDUbDkxhWQ7lX9qAl5dsolDj9b5rYvEfJToqlNgw1\",\"FkCourseDefinition\":\"33\",\"FkBvoCourseDaypart\":\"4\",\"IncludesExam\":null,\"ManualBookedUp\":null,\"Inactive\":null}");
