Hello everyone,
I have already connected d365 CRM online with the .net core console app using client id, clients secret, and organization URI. But it is throwing an error on connecting with on-prem.
here is the error.

Hi,
I have not tried .Net Core SDK with on-premise.
You can try registering your on-premise app first:
docs.microsoft.com/.../walkthrough-register-app-active-directory
Sorry, it is necessary to use .net core. Can't change that.
Hi,
Yes, that is the reason you need to access it using CRMServiceClient (.Net Framework).
You can access an on-premise environment, without registering an App (and using AD (or NTLM) Authentication).
Only Client Secret and OAuth can be used to connect .net core with CRM.
The problem is I don't get redirect URI on registering the app, that's why I am using client secrect and I am using .net core.
Hi,
Thank you for your query.
For On premise, you need to connect using Authentication Type: AD, which is not supported with ServiceClient.
I believe this is meant for only Datavers (Online) version.
For On-premise, you need to use .Net Framework, please look into following article:
Your AD Connection string should be something like:

All responses (
Answers (
string url = ;
string conn = $@"
Url = {url};
AuthType = AD;
RequireNewInstance = True";
You can add username and password as well.
