WCF + Json = wrong serialization

Question

Why this WCF 3.5 method

[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Jso         


        

Answer 1

This is a security feature that has been added to the JSON serialization in .NET 3.5. It's a container object, so instead of, say, results[0], you would just say results.d[0]. Read this article for more information.

Answer 2

Have you tried changing the BodyStyle property of your [WebGet] Attribute so that responses aren't wrapped?

Answer 3

I'm assuming you are using <enableWebScript/> in your behavior config, replace that with <webHttp defaultOutgoingResponseFormat="Json"/> and you will get json without the root "d" and without the "__type" props.

However, I've only tested this in 4.0

I also don't use any attributes in code.
