How to enable strict conversion of json.net?

Here is my dto of action for json input :

public class GreetRequest
{
    public string Message{get;set;}
}

When the json is post from the client:

{
    "Message":true
}

the json.net would convert the Boolean to string automatically:

true -> “true” 

By far，I wrote a converter to enforce the rule:

public class StrictStringConverter : JsonConverter
{
       readonly JsonSerializer defaultSerializer = new JsonSerializer();

       public override bool CanConvert(Type objectType)
       {
           return objectType.IsStringType();
       }

       public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
       {
           switch (reader.TokenType)
           {
               case JsonToken.String:
               case JsonToken.Null:
                   return defaultSerializer.Deserialize(reader, objectType);
               default:
                   throw new JsonSerializationException();
           }
       }

       public override bool CanWrite { get { return false; } }

       public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
       {
           throw new NotImplementedException();
       }
   }

   public static class JsonExtensions
   {
       public static bool IsStringType(this Type type)
       {
           type = Nullable.GetUnderlyingType(type) ?? type;
           if (type == typeof(string))
               return true;
           return false;
       }
   }

the converter is configure at startup.cs

 services.Configure<MvcNewtonsoftJsonOptions>(options => { 
                    options.SerializerSettings.Converters.Add(new StrictStringConverter());
                });

Question:

1. Is there any out of box way of strict conversion for json input, without writing any converter manually.
