CRMServiceClient does not try to connect to Dynamics CRM

Question

Using the latest SDK for Dynamics CRM, I am attempting to create a new CRMServiceClient([ConnectionString]). I try to do anything with it including a WHOAMI request, and I get Unable to Login to Dynamics OrganizationServiceProxy is null. When I run fiddler, nothing is even attempting to communicate to the server to attempt a login. I am unsure what is wrong, as I would have thought newing up a CRMServiceClient would have tried to connect since OrganizationServiceProxy is a child object of CRMServiceClient. Anyone have any ideas how to approach solving this?

var temp = new CrmServiceClient(ConfigurationManager.ConnectionStrings["con‌n"].ConnectionString‌);

<add name="conn" connectionString="AuthType=AD; Url=Url/DEVCRM; Username=User; Password=pass;"/>

Please share your code and exception details. With the information you provided it's hard to tell what's wrong. — Henk van Boeijen
Most likely your connection string is bad, but with the information you provided it's not possible to help you — Pawel Gradecki
var temp = new CrmServiceClient(ConfigurationManager.ConnectionStrings["conn"].ConnectionString); <add name="conn" connectionString="AuthType=AD; Url=Url/DEVCRM; Username=User; Password=pass;"/> So when I run the 1 line of code, the OrganizationServiceProxy is null. the connection string is above as well. Changed URL, Username and password to hide true information. — James W

Please note that CrmServiceClient has a boolean property called IsReady, which is a good way to check if it's in a proper state.

And for reference, here are example connection strings for the various environment types:

CRM 2016 and Dynamics 365 online:

<add name="dev26" connectionString="Url=https://dev26.crm.dynamics.com; [email protected]; Password=Pass; AuthType=Office365" />

On-premise with integrated security:

<add name="prod" connectionString="Url=http://myserver/AdventureWorksCycle;"/>

On-premise with credentials:

<add name="prod" connectionString="Url=http://myserver/AdventureWorksCycle; Domain=mydomain; Username=administrator; Password=password; AuthType=AD;"/>

On-premise IFD before CRM 2016:

<add name="prod" connectionString="Url=https://contoso.litware.com; [email protected]; Password=password; AuthType=IFD;"/>

On-premise IFD for CRM 2016 and later (v8.0+)

<add name="prod" connectionString="ServiceUri=https://contoso.litware.com/contoso; Domain=contoso; Username=contoso\administrator; Password=password; AuthType=IFD; LoginPrompt=Never;" />
