Use of the WS-Trust authentication security protocol when connecting to Microsoft Dataverse is no longer recommended and has been deprecated. You need to switch over to using an OAuth based connection string. Please refer to the sample code below:
using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using Microsoft.Xrm.Tooling.Connector;
using System;
namespace Dynamics365ConsoleApp
class Program
static void Main(string[] args)
CrmServiceClient crmSvc = getOrganizationService();
Console.ReadLine();
public static CrmServiceClient getOrganizationService()
CrmServiceClient crmSvc = null;
String connString = "AuthType=OAuth;[email protected];Password=xxxxxx;Url=https://xxxxxx.crm4.dynamics.com;AppId=51f81489-12ee-4a9e-aaae-a2591f45987d;RedirectUri=app://58145B91-0C36-4500-8554-080854F2AC97;TokenCacheStorePath=c:\\MyTokenCache;LoginPrompt=Auto";
crmSvc = new CrmServiceClient(connString);
if (crmSvc != null)
var whoAmIResponse = ((WhoAmIResponse)crmSvc.Execute(new WhoAmIRequest()));
if (whoAmIResponse != null)
Console.WriteLine("Connection OK....");
Console.WriteLine(whoAmIResponse.UserId);
Console.WriteLine("Connection KO....");
catch (Exception e)
Console.WriteLine("ERROR...");
Console.WriteLine(e.Message);
return crmSvc;
