I successfully deployed the Identity server and it is working fine also configure the SMTP settings on the VPS but when try to set up it with the ASP.Net Core 3.1 Application unable to find the SMTP in the features using IIS. I used No Managed Code As Application Pool. Below is the image regarding my problem
In .net core no need for asp.net setting. It was needed in the older version. We just need to change the configuration in appsettings.json for (SMTP) email setup also for the MTA(Third Party)
