Handling JSON in windows phone 7

Question

I have a JSON file coming from the internet:

string JSON = reader.ReadToEnd();

It works perfectly, the problem is here:

NewsList = JsonConvert.DeserializeObject<News>(JSON) as News;

This works perfectly on WP8 project, but WP7 somewhy fails it. Here is my News class:

    class News
    {
        [JsonProperty("jsonrpc")]
        public string Jsonrpc { get; set; }
        [JsonProperty("id")]
        public string Id { get; set; }
        [JsonProperty("result")]
        public Result Result { get; set; }
    }
    public class Result
    {
        private List<Article> articles = new List<Article>();
        [JsonProperty("articles")]
        public List<Article> Articles { get { return articles; } }
    }
    public class Article
    {
        [JsonProperty("text")]
        public string Text { get; set; }
        [JsonProperty("id")]
        public int Id { get; set; }
        [JsonProperty("date")]
        public long Date { get; set; }
        [JsonProperty("title")]
        public string Title { get; set; }
        [JsonProperty("author")]
        public string Author { get; set; }
        [JsonProperty("imageURL")]
        public string ImageURL { get; set; }
    }

Here is the error:

Attempt to access the method failed: WP7RTURelease2.HomePage+News..ctor()

Try making your News class public.
