I need to make rest requests to SharePoint from a simple command line utility (C#).
I've used CSOM/Caml with OfficeDevPnP previously but now need to perform rest calls to lists.
I used this code to authenticate:
AuthenticationManager authMgr = new AuthenticationManager();
ctx = authMgr.GetSharePointOnlineAuthenticatedContextTenant(spsite, spusername, sppassword);
How do I authenticate for rest calls over HttpClient?
