Posted on by Sohail@@2156 30

I have a class library project already developed that create Products from F&O to Field Service through Integeration.

Microsoft has deprciated  the WS-Turst (Office 365 Authentication) and Recommended to use OAuth.

Integration has been break after Code update

Connection is fine at console app or when i consume hosted integration project but when it run through the D365 Finance and Operation it give below error.

""Unable to connect to CRM: Could not load type 'Microsoft.IdentityModel.Clients.ActiveDirectory.LogCallback' from assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=2.23.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.\r\nCould not load type 'Microsoft.IdentityModel.Clients.ActiveDirectory.LogCallback' from assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=2.23.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.Unable to Login to Dynamics CRM\r\nUnable to Login to Dynamics CRMOrganizationWebProxyClient is null\r\nOrganizationWebProxyClient is nullOrganizationWebProxyClient is null\r\nOrganizationWebProxyClient is null""

CRM Connection Code is here 

private static string ConnectToMSCRM()
{

string connectionStatus = "";
try
{
//New Authentication OAuth
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

//New Authentication ClientSecret
var connectionString = "AuthType=ClientSecret;url=https://******.crm4.dynamics.com;ClientId=8b50f998-5a44-4307-8317-b6fb52bcf26c;ClientSecret=yty8Q~WdF3Xf8Nn0uTr4uCyJ0sUYD1K-KHd3Xapo";
CrmServiceClient crmConn = new CrmServiceClient(connectionString);
service = crmConn.OrganizationWebProxyClient ;

// Old obsolete code
//ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
//ClientCredentials credentials = new ClientCredentials();
//credentials.UserName.UserName = UserName;
//credentials.UserName.Password = Password;
//Uri serviceUri = new Uri(SoapOrgServiceUri);
//OrganizationServiceProxy proxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
//proxy.EnableProxyTypes();
//service = (IOrganizationService)proxy;
}

catch (Exception ex)
{
connectionStatus = "Error!"   "Error occurred while connecting to CRM "   ex.ToString();
}
return connectionStatus;

}

    Hello,

    Doublecheck that you have the right version of "Microsoft.IdentityModel.Clients.ActiveDirectory" references - the version should be 2.28.3.

    I have a little more in formation in my post - butenko.pro/.../

    Thanks Andrew,

    2022_2D00_06_2D00_28_5F00_13_2D00_26_2D00_06.png

    I have CRM online version 9.2 and using Xrm.Tooling.CoreAssembly version 9.1.0.13 which have dependency on Microsoft.IdentityModel.Active Directory version >=3.19.8

    The strange things is if I upgrage or downgrade the version of dll Microsoft.IdentityModel.Active Directory the execption is always 

    Exception:

    "Unable to connect to CRM: Could not load type 'Microsoft.IdentityModel.Clients.ActiveDirectory.LogCallback' from assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=2.23.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.\r\nCould not load type 'Microsoft.IdentityModel.Clients.ActiveDirectory.LogCallback' from assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=2.23.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.Unable to Login to Dynamics CRM\r\nUnable to Login to Dynamics CRMOrganizationWebProxyClient is null\r\nOrganizationWebProxyClient is nullOrganizationWebProxyClient is null\r\nOrganizationWebProxyClient is null".

    Code is running is in console but when run through F&O plateform it give above exception.

    Hello,

    I created a supersimple console app exactly with your version of the Xrm Tooling and everything worked from the very first attempt.

    Here is what I have in packages:

    Here is the code I used:

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Xrm.Tooling.Connector;

namespace ConsoleApp7
{
    class Program
    {
        static void Main(string[] args)
        {
            var service = new
                CrmServiceClient("AuthType=ClientSecret; Url=https://instance.crm.dynamics.com; ClientId=Put Guid Here;ClientSecret=Put Your Secret Here");

            if (!service.IsReady)
            {
                Console.WriteLine(service.LastCrmError);
            }
            else
            {
                Console.WriteLine("Connected");
            }

            Console.ReadLine();
        }
    }
}

    I used Framework 4.6.2.

    Yes, It is working in console as i mentioned already, but when same code run through F&O Interface/Platform it always show exception

     The same line of code running fine in console but confuse why when through F&O Platform it return all null (authority, token and OrganizationWebproxyclient)

    Ahh. Gotcha. Dunno how to help you here. One idea that I have in mind is to create some proxy (Azure Function for example) and call it from your F&O Code.

    Have you found a solution to this problem? I have the same error when I run it from F&O. In the console, everything works without errors.

    Yes, Volodymyr Vit 

    1st  you need to get Token from Azure Active Directory by passing the tenant id in given blow code and then pass it to OrganizationWebProxyClient.

    Here is sample code that i used and it solve the issue and working in F&O side

    static IOrganizationService service = null;

private static string ConnectToMSCRM(string clientId, string clientSecret, string url)
{
string connectionStatus = "";
try
{
#region New Online CRM Authentication Auth 2.0
// Dynamics CRM Online Instance Base URL
string crmBaseUrl = url;
// client id and client secret of the application
ClientCredential clientCrendential = new ClientCredential(clientId, clientSecret);
// Authenticate the registered application with Azure Active Directory.
Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext authContext = new Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext("https://login.microsoftonline.com/53b0f650-ed58-4cf1-b3af-776ee*******");

AuthenticationResult authResult = authContext.AcquireTokenAsync(crmBaseUrl, clientCrendential).Result;
var accessToken = authResult.AccessToken;

Uri serviceUrl = new Uri(crmBaseUrl   @"/XRMServices/2011/Organization.svc/web?SdkClientVersion=9.2");
using (OrganizationWebProxyClient orgWebProxyClient = new OrganizationWebProxyClient(serviceUrl, false))
{
orgWebProxyClient.HeaderToken = accessToken;
service = orgWebProxyClient != null ? (IOrganizationService)orgWebProxyClient : null;

}

#endregion
}
catch (Exception ex)
{
connectionStatus = "Error!"   "Error occurred while connecting to CRM "   ex.ToString();
}
return connectionStatus;
}
