JsonHttpClient failed to deserialize some resource?

[Tennyleaz]

I want to get API limits using List Organization Limits function, and I define my own object like:

public class LimitBase
{
    [JsonProperty(PropertyName = "Max")]
    public int Max { get; set; }
    [JsonProperty(PropertyName = "Remaining")]
    public int Remaining { get; set; }
}

public class DailyApiRequest : LimitBase
{
    [JsonProperty(PropertyName = "Workbench")]
    public LimitBase Workbench { get; set; }
    [JsonProperty(PropertyName = "Salesforce Mobile Dashboards")]
    public LimitBase MobileDashboards { get; set; }
    [JsonProperty(PropertyName = "Salesforce Touch")]
    public LimitBase Touch { get; set; }
}

public class Limit
{
    [JsonProperty(PropertyName = "DailyApiRequests")]
    public DailyApiRequest DailyApiRequests { get; set; }
    [JsonProperty(PropertyName = "DataStorageMB")]
    public LimitBase DataStorageMB { get; set; }
    [JsonProperty(PropertyName = "FileStorageMB")]
    public LimitBase FileStorageMB { get; set; }
}

HTTP get request will return a proper json string, but JsonHttpClient cannot successfully deserialize the string to my Limit class. I found JsonConvert.DeserializeObject<T>(jObject.ToString()); in JsonHttpClient.cs line 55 is returning null.

If I copy the response string and manually convert it like:

Limit limit = JsonConvert.DeserializeObject<Limit>(resopnseString);

The deserialization will always success. How can we improve/fix the built in JsonHttpClient class?
