Greetings:

I'm trying the examples in the SDK, and now I'm at the Simplified Connecting String Example listed here [https://msdn.microsoft.com/en-us/library/jj602970(v=crm.7).aspx]

This is my code in the app.config:

<add name="Server=CRM Online, organization=contoso, user=someone"
         connectionString="Url=https://pspas.crm.dynamics.com;
         Username=nxxxx.mxxxz@pspas.onmicrosoft.com;
         Password=xxxx; 
         authtype=Office365"/>

However, I'm receiving the following error:

I'm using VS 2015 and I'm trying to connect to CRM Online 2016.

What I'm missing in my connection string?

Well, it's clearly showing that there is authentication failure and so the Org service is null. But you are trying to access properties/methods of it, you will get object reference errors.

Step1 - Make sure your connection string (user id, password, url) is correct. An example of connection string from MSDN

<add name="MyCRMServer" connectionString="AuthType=Office365;Username=jsmith@contoso.onmicrosoft.com; Password=passcode;Url=contoso.crm.dynamics.com"/>

Step2- If you are following the MSDN Example as it is, check what is the "connectionString" variable value you are getting in the "Run" method
is it what we are expecting or getting any other?

You can also check Organizationservice's last error/fault property to check for more details on why authentication failed (AFAIK).

Checked step1 and step2. I'm receiving the same error. Credentials, username, password, and url are correct.

Hi NellMartinez,

I just tested this and had issues with the latest version of Microsoft.IdentityModel.Clients.ActiveDirectory assembly. I downgraded it to 2.28.0 and it works.

Here's the code.

var connectionString = "Url=https://orgname.crm.dynamics.com; Username=user@orgname.onmicrosoft.com; Password=password; authtype=Office365"; // Connect to the CRM web service using a connection string. CrmServiceClient conn = new CrmServiceClient(connectionString); // Cast the proxy client to the IOrganizationService interface. var _orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

Please see below for the NuGet packages and versions I have installed in my console app.

Hi Nithya;

My connection strings looks like this at this moment:

<add name="Server=CRM Online" connectionString="Url=disco.crm.dynamics.com/.../v8.1;Username=xxxx.xxxx@pspas.onmicrosoft.com;Password=xxxx!;Domain:pspas;"/>

And now I'm receiving this error;

The application terminated with an error.

Organization name cannot be null or empty.

Parameter name: Organization Name

{System.ArgumentNullException: Organization cannot be null or empty.

Parameter name: Organization Name

Hi,

You could use the following connection string.

Url=https://devcrm.vzdev.ch/devcrm;Domain=vzdev;UserName=user@vzdev.ch;Password=pass;AuthType=IFD

Also refer the link below.

you shouldn't be using the Discovery service to connect to CRM Organization. Have you tried the solution provided by @Nadeeja Bomiriya above?
