I really need the SharePointOnlineCredentials class to work in Dot Net Core under CSOM. It is so simple to use, and your work around(s) are complicated and not possible for me. I work for a large company with a large online SharePoint site. The corporation refuses to give out application codes to work around my security, but I can create a user and password to login to the SharePoint site and update files. Why can I not automate this in Dot Net Core? The work around(s) for this one feature are crazy. Days of coding to run into brick walls that are not necessary. I'm very frustrated...
