public class JSON_Browse_Root
{
    public string browse_content { get; set; }
    public List<JSON_Browse_Content> Content { get; set; }

public class JSON_Browse_Content
{
    public string link { get; set; }
    public string image { get; set; }
    public string title { get; set; }
    public string description { get; set; }
    public string rating { get; set; }
    public string genre { get; set; }

using (var client = new HttpClient())
{
    using (HttpResponseMessage response = await client.GetAsync("https://myjsonurl.com"))
    using (HttpContent responseData = response.Content)
    {
        var jsonData = await responseData.ReadAsStringAsync();
        var root = JsonConvert.DeserializeObject<JSON_Browse_Root>(jsonData);
    }
