Cannot connect to new CRM Online Organisation

(0) ShareShare
ReportReport
Posted on by Joseph McGregor Mac... 597

I created a new CRM Online organisation with new Office 365 accounts (onmicrosoft.com) and C# client code to create/connect to the OrganistionService does not work

I am receiving an error stating that identityProvider is null in an internal SDK method

The plugin registration tool in the SDK connects to the CRM organisation, but none of the SDK sample code will connect

I have tried to connect using several methods

1. The connection string sample code project "QuickStart with Simplified Connection" in(SDK\SampleCode\CS\QuickStart)

2. The WPF Client sample code project "QuickStartXRMToolingWPFClient" in (SDK\SampleCode\CS\XRMTooling\QuickStartXRMToolingWPFClient)

3. My Dev Tool on GitHub - this connects initially to the discovery service which appears to be the point the error is thrown https://github.com/josephmcmac/XRM-Developer-Tool (CRM-SDK-8.2 branch)

Has anyone else received this error and know how to fix it?

    Never got this error before, could you share your simplified connection code ?

    It is the SDK sample code virtually untouched. The code is located in the latest SDK (8.2) at the path SDK\SampleCode\CS\QuickStart

    The only change I did was
    1. Add a connection string to the app.config as per the example and SDK instructions

    <add name="onlineconnection"
             connectionString="Url=mcgregor2017.crm6.dynamics.com; Username=joseph@mcgregor2017.onmicrosoft.com; Password=XXXXXXXX; authtype=Office365"/>


    2. Modify the Run() method to only call a WhoAmIRequest after creating the IOrganizationService

    have you tried to use your organization unique name. So the connection string would be like = "url = 45ab2258.crm6.dynamics.com" where the 45ab2258 is your organization unique name. You can find the organization unique name in Setting - customizations - developer resources - unique name

    This is resolved now. The client code suddenly started to connect correctly without any changes

    Not sure if I have to wait a while after creating a new online orgnaisation to connect from a C# client or something, or something was changed server side

    For the SDK sample code I did have to upgrade the code to reference SDK v8.2 assemblies, instead of v8.0 assemblies, but this was to fix an unrelated issue/error where new CRM Online does not allow connections from old SDK assemblies
