asp.net web api - Setting IgnoreSerializableAttribute Globally in Json.net

Question

I'm working on a ASP.NET WebApi (Release Candidate) project where I'm consuming several DTOs that are marked with the [Serializable] attribute. These DTOs are outside of my control so I'm not able to modify them in any way. When I return any of these from a get method the resulting JSON contains a bunch of k__BackingFields like this:

<Name>k__BackingField=Bobby
<DateCreated>k__BackingField=2012-06-19T12:35:18.6762652-05:00

Based on the searching I've done this seems like a problem with JSON.NET's IgnoreSerializableAttribute setting and to resolve my issue I just need to set it globally as the article suggests. How do I change this setting globally in a ASP.NET Web api project?

Answer 1

I found easy way to get rid of k__BackingField in the names.

This fragment should be somewhere in the Application_Start() in Global.asax.cs:

JsonSerializerSettings jSettings = new Newtonsoft.Json.JsonSerializerSettings();
GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings = jSettings;

Looks like the default setting takes care of it.
