How Can I Customize Json.NET SerializerSettings in ASP.NET Web API?

Tailoring Json.NET SerializerSettings in ASP.NET Web API

ASP.NET Web API uses Json.NET for serializing and deserializing objects. But how do you customize the JsonSerializerSettings? For example, you might need to include type information in your JSON output. While you can inject settings into the .Serialize() method directly, Web API handles serialization internally, preventing direct settings injection.

The solution lies in configuring the JsonSerializerSettings through the Formatters.JsonFormatter.SerializerSettings property of the HttpConfiguration object.

This code, placed within the Application_Start() method, demonstrates this customization:

<code class="language-csharp">protected void Application_Start()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.Formatting =
        Newtonsoft.Json.Formatting.Indented;
}</code>

This method gives you complete control over ASP.NET Web API's serialization settings, allowing you to precisely shape the JSON output to your application's needs.
