SDK Simplified connection string in app.config: "Object reference not set to an instance of an object."

Posted on by Community Member Microsoft Employee

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?

    I was receiving the same error when trying to connect the on premise CRM for developing a console application. Using the unique org name still didn't fix the problem. I have changed my connection string as following and it works fine now.

    In program.cs file

    string connectionstring = ConfigurationManager.ConnectionStrings["DynamicsCRM365"].ConnectionString;
    Microsoft.Xrm.Tooling.Connector.CrmServiceClient conn = new Microsoft.Xrm.Tooling.Connector.CrmServiceClient(connectionstring);
    IOrganizationService service = conn.OrganizationServiceProxy;

    In App.Config (Or put it in Web.Config)

    <connectionStrings>
    <add name="DynamicsCRM365" connectionString="Url=https://yourcrmurl/orgname; Domain=domainname;UserName=username;Password=password;authtype=AD" />
    </connectionStrings>

    Hope, the above example will help you. 

     

    Thanks

    Thank you Daniel! I've been struggling so much on how different not reliable is the MSDN references. I hope they can update documentation as rapidly they are pushing updates to the SDK.

    Hi Nell,

    You can try directly using the URL of the CRM as nithya said. Hope it works

    Hi,

    Can try using the following code? 

    IOrganizationService services = CRMConnectionDefault();

public static IOrganizationService CRMConnectionDefault()

        {
            ClientCredentials credentials = new ClientCredentials();
            credentials.Windows.ClientCredential = new System.Net.NetworkCredential("userName", "password", "domain");
            Uri organizationUri = new Uri("http://url/domain/XRMServices/2011/Organization.svc");
            OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(organizationUri, null, credentials, null);
            serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
            serviceProxy.Timeout = new TimeSpan(0, 6, 0);
            return (IOrganizationService)serviceProxy;
        }

    Hope it helps,

    Hi!

    Are you using the CRM 2016 SDK? There's apparently a bug in it making it require the unique organisationname to be used in the url instead of your organisation display name.

    Aileen recently wrote a blog post for this and it solved my issues with accessing the organizationservice with the 2016 SDK:

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

    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.

    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 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.
