Question

I am now using asp.net mvc and wondering what is a better choice using the built in Json or Json.Net I am not sure if one has an advantage over another.

Also if I do choose to go down the route of Json.Net then should I go with the stable version or beta 4? I am not sure how unstable the betas are.

You may have issues serializing dates with the MVC JSON. My answer to that post is repeated below.

If you are not tied to the MS JSON serializer you could use Json.NET. It comes with an IsoDateTimeConverter.
This will serialize dates into an ISO
8601 formatted string.

For instance, in our project
serializing myObject is handled via
the following code.

JsonNetResult jsonNetResult = new JsonNetResult();
jsonNetResult.Formatting = Formatting.Indented;
jsonNetResult.SerializerSettings.Converters.Add(new IsoDateTimeConverter());
jsonNetResult.Data = myObject;

If you decide to take the Json.NET
plunge you’ll also want to grab
JsonNetResult as it returns an
ActionResult that can be used in
ASP.NET MVC application. It’s quite
easy to use.

with Json.NET

We are currently using Json.NET v3.5 Beta 4 and have not encountered issues. However, we haven’t really taxed our system as it hasn’t yet entered production. Your mileage may vary depending on how much of the framework you are using.

Hope this helps.
