Good afternoon,

I'm creating a class that connects to CRM On Line version v.9.2, but I'm getting the error "Unable to Login to Dynamics CRMOrganizationServiceProxy is null", can someone help me, below is the code I'm using

D365ConsoleCRUD namespace
{
class Program
{
static void Main(string[] args)
{
OAuthConnexion connection = new OAuthConnexion();
CrmServiceClient svc = connection.ConnectionOAuth();

if(svc.IsReady)
{
Console.WriteLine("With Connection");
}
else
{
Console.WriteLine("No Connection");
}

}
}
}

public class OAuthConnection
{
public CrmServiceClient ConnectionOAuth()
{

string url = "">xxxxxx.crm2.dynamics.com";
string userName = "xxxx@hotmail.com";
string passWord = "xxxxx";

string con = $@"
Url = {url};
AuthType = Office365;
userName = {userName};
passWord = {passWord};
RequiredNewInstance = True";

CrmServiceClient svc = new CrmServiceClient(con);
return svc;
}

}

RE: Failure in Conexion CRM On Line

Hello Arshad,

Thanks for the feedback, I tried your way and failed, I tried from the article optimallogics.com/.../ , but success.

Create the connection string and nothing, I believe that it is missing some parameter.

Here's the code I'm using

Void main:

using (CrmServiceClient svcClient = new CrmServiceClient(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))

{

if (!svcClient.IsReady)

{

Console.WriteLine("unable to connect!");

return;

}

WhoAmIRequest request = new WhoAmIRequest();

WhoAmIResponse response = (WhoAmIResponse)svcClient.Execute(request);

Console.WriteLine("UserId =" + response.UserId.ToString());

}

APP Config:

<connectionStrings>

<add name="ConnectionStrings"

connectionString="

AuthType=ClientSecret;url=XXXXX.crm2.dynamics.com;

ClientID=XXXXXX-126c-XXXX-a87b-XXXXXX;

ClientSecret='XXXX-XXXX-XXXX-aceb-XXXXXX"/>

</connectionStrings>

The error I'm getting is

Object reference not set to an instance of an object

Thanks

RE: Failure in Conexion CRM On Line

Hi Ricardo,

You are still using an Office365 AuthType which has now been deprecated.

You now need to use an AuthType = OAuth and a modified connection string.

See the deprecation note from Microsoft below.

Use of Office365 authentication with Microsoft Dataverse (Microsoft Dataverse) - Power Apps | Microsoft Docs

Hopefully modifying the connection string should allow you to connect.

Regards,

Shaun
