I looked into a "fun" little problem yesterday where we were seeing occasional errors in some of our ASP.NET Core code which calls down into the ASP.NET Core Identity UserManager. We were getting a range of NullReferenceException and ObjectDisposedExceptions as well as various exceptions from Npgsql.NpgsqlConnection (we use Postgres rather than SQL in this project) stating things such as "Connection already open".
