JsonContent.cs

using System.Net.Http;
using System.Text;
using Newtonsoft.Json;

namespace Lenkan.StrengthLog.Data.Couch
{
    public class JsonContent : StringContent
    {
        public JsonContent(string s) : base(s, Encoding.UTF8, "application/json")
        { }

        public JsonContent(object o) : this(JsonConvert.SerializeObject(o))
        { }
    }
}
