Posted on by zahid.tectree 45

Hi ALL-IN ,

I am getting a WS-Trust Authentication error in my console application(which consumes API) due to WS-Trust and Office365 authentication being removed.

comunityApi.txt

I know it can be resolved by OAuth Authentication but need to replace IOrganizationService.

need some help on how to replace IOrganizationService .

I have also attached the code for reference.

Thanks,

I have the same question (0)

    Hi,

    You need to use below code to connect to CRM

    public IOrganizationService createConnection()

           {

               try

               {

                   CrmServiceClient crmSvc = new CrmServiceClient(ConfigurationManager.ConnectionStrings["MyCDSServer"].ConnectionString);

               if (crmSvc.IsReady)

               {

                    return crmSvc ;

               }

               else

    {

    Console.WriteLine("Error:"+crmSvc .LastCrmError);

    return null;

    }

               }

               catch (Exception ex)

               {

                   // Console.WriteLine("Exception caught - " + ex.Message); //TTC_KH_ConsoleComment

               }

               return null;

           }

    <connectionStrings>  

       <add name="MyCDSServer" connectionString="AuthType=OAuth;Username=;Password=;Url=;AppId=51f81489-12ee-4a9e-aaae-a2591f45987d;RedirectUri=app://58145B91-0C36-4500-8554-080854F2AC97;LoginPrompt=Auto" />

    </connectionStrings>

    Add Username and password.
