Hi,
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;Username=xxxx@xxxx.onmicrosoft.com;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";
try
{
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);
}
else
{
Console.WriteLine("Connection KO....");
}
}
}
catch (Exception e)
{
Console.WriteLine("ERROR...");
Console.WriteLine(e.Message);
}
return crmSvc;
}
}
}
Please note: The AppId and RedirectUri provided above are examples of working application registration values. These values work everywhere online services are deployed. However, they are provided here as examples and you are encouraged to create your own application registration in Azure Active Directory (AAD) for applications running in your tenant.
