Here is a complete Azure Function source code for serializing/deserializing objects using JsonNet:

#r "Newtonsoft.Json"

using System.Net;
using Newtonsoft.Json;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    dynamic body = await req.Content.ReadAsStringAsync();
    var e = JsonConvert.DeserializeObject<EventData>(body as string);
    return req.CreateResponse(HttpStatusCode.OK, JsonConvert.SerializeObject(e));
}

public class EventData
{
    public string Category { get; set; }
    public string Action { get; set; }
    public string Label { get; set; }
}

Sample input (request body):

{
    "Category": "Azure Functions",
    "Action": "Run",
    "Label": "Test"
}

Sample output:

"{\"Category\":\"Azure Functions\",\"Action\":\"Run\",\"Label\":\"Test\"}"
