Deserialization with json.net

Question

I am coming across a very weird situation. I have two sections of code where two separate rest calls are made to web service and the json from the web server is deserialized using Json.Net. Here are my sections of code

1st Section:

string AuthoraizationTicket = "";
                using (var client = new WebClient())
                {
                    string url = "https://maxcvservices.dnb.com/Authentication/V2.0/";

                    client.Headers.Add("x-dnb-user", "P200000216EA4E620E64DD980D494E7A");
                    client.Headers.Add("x-dnb-pwd", "password#1");

                    try
                    {
                        var response = client.DownloadString(url);
                        var DeserializedJson = JsonConvert.DeserializeObject<RootObject>(response);
                        AuthoraizationTicket = DeserializedJson.AuthenticationDetail.Token;

                    }
                    catch (Exception ex)
                    {

                    }

The above section executes correctly and Json is Deserialized Properly.

Section 2:

using (var wClient = new WebClient())
                    {
                        string DUNS = txtDUNS.Value;
                        string RTNG_TRND = String.Format("https://maxcvservices.dnb.com/V5.0/organizations/{0}/products/RTNG_TRND", DUNS);
                        wClient.Headers.Add("Authorization", AuthoraizationTicket);

                        try
                        {
                            var resp = wClient.DownloadString(RTNG_TRND);
                            var RatingAndTrend = JsonConvert.DeserializeObject<RatingAndTrendDnB>(resp);
                            string creditCondition = RatingAndTrend.OrderProductResponse.OrderProductResponseDetail.Product.Organization.Assessment.FinancialConditionText.Value;
                            }
                        catch (Exception ex)
                        {

                        }
                    }

The above section throws an exception at

var RatingAndTrend = JsonConvert.DeserializeObject<RatingAndTrendDnB>(resp);

Line saying:

Any help will be appreciated

Answer 1

It appears that section 2 is either:

• A: Running in a different assembly than section 1, and does not have the Newtonsoft reference.
• B: Referencing a different version of Newtonsoft.JSON.

Ensure in your NuGet package system (if that is what you are using for references) that you have the same version of Newtonsoft.JSON installed.
