How to prevent web API from serializing my model from JSON to string

Question

How can I take control of the JSON serialization and not have web API serialize my model?

Currently the resulting string is double serialized because I am doing it AND web api is performing it.

public HttpResponseMessage GetUsers()
{
    var users = _service.GetUsers()
    var model = new UserResponse(users);

    var json = JsonConvert.SerializeObject(model);


    return Request.CreateResponse(HttpStatusCode.OK, json, Configuration.Formatters.JsonFormatter);
}

I am going to add some customization so I need to take control of this JSON serialization part.

Use StringContent object as the .Content property of the HttpResponseMessage. See this question — maccettura

You can try this

public HttpResponseMessage GetUsers()
{
    var users = _service.GetUsers()
    var model = new UserResponse(users);

    var json = JsonConvert.SerializeObject(model);
    var response = this.Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StringContent(json , Encoding.UTF8, "application/json");
    return response
}

or

public IHttpActionResult GetUsers()
{
    var users = _service.GetUsers()
    var model = new UserResponse(users);
    return Ok(model);
}

or

public UserResponse GetUsers() 
{
    var users = _service.GetUsers()
    var model = new UserResponse(users);
    return model;
}
