How to Configure Custom JsonSerializerSettings in ASP.NET Web API?

Configuring custom JsonSerializerSettings in ASP.NET Web API (using Json.NET)

ASP.NET Web API leverages Json.NET to handle serialization and deserialization of objects. However, can you specify your own JsonSerializerSettings instance?

Question:

How to define a custom JsonSerializerSettings object for Json.NET in ASP.NET Web API? For example, how do I add type information to the generated JSON string?

Answer:

To customize JsonSerializerSettings, use the Formatters.JsonFormatter.SerializerSettings property in the HttpConfiguration object.

The following is an example in the Application_Start() method:

protected void Application_Start()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.Formatting =
        Newtonsoft.Json.Formatting.Indented;
}

By modifying this property, you can specify the desired JsonSerializerSettings, including specific formatting options, and even override the default behavior of serialization and deserialization.
