[Call SharePoint Online rest api from console c# app with modern auth]
- I am trying to call sharepoint search api from console app, in tenant only Modern authentication is active.
So i created Azure App and give there api permission ("AllSites.Read", "Sites.Search.All","Sites.Read.All", "Files.Read.All").
- I am able to get auth token , but getting unauthorized error during api call
After nuget upgraded with Microsoft.identiy.model version verion v 4.4.1. Now able to fix this issue.
