问题 So it happens that you can prevent breeze json serialization of some properties using data annotations on your model by like this(well if you are using EF6 with JSON.NET on the backend)...

问题 Just as the title says I am not getting the MVC Controller to return HttpResponseMessage correctly. [HttpGet] [AllowAnonymous] public HttpResponseMessage GetDataAsJsonStream() { object returnObj = new { Name = "Alice", Age = 23, Pets = new List<string> { "Fido", "Polly", "Spot" } }; var response = Request.CreateResponse(HttpStatusCode.OK); var stream = new MemoryStream().SerializeJson(returnObj); stream.Position = 0; response.Content = new StreamContent(stream); response.Content.Headers

问题 Why my custom JsonConverter.WriteJson() method doesn't get called ? class MyType{ [JsonConverter(typeof(DocumentXamlDeserializer))] public string GuiData { get; set; } public string SimpleString; } Although the ReadJson does get called: public class DocumentXamlDeserializer : JsonConverter { public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { writer.WriteValue(Gui.Handler.SerializeData()); } public override object ReadJson(JsonReader reader, Type
