Authenticate our Asp.NET Core console application against SharePoint online

Question

We have a newly created SharePoint online tenant, which have its SharePoint app-only permissions disabled >> and we do not want to enable it.

Now we are going to write a console application to integrate with SharePoint online >> but one of the most confusing thing i have ever read is about how we can do so... as most of the approaches mentioned are using deprecated approaches.. so finally i found those 2 main approaches:-

AND

https://sharepointstew.wordpress.com/2021/07/07/app-only-authentication-in-sharepoint-online-using-latest-azure-sdk/

so i have the following questions:-

1) which approach is still not deprecated?
2) which approach is recommended and why?
3) is there a third approach which is better to use?

Thanks

Answer 1

Hi @john john ,
I would rather recommend you to take first approach.In second link ,such as SharePointPnPCoreOnline and Microsoft.Azure.KeyVault which are now deprecated and are not maintained.The first approach use CSOM will be better for you.
