## Description

ICG.AspNetCore.Utilities.CloudStorage is a collection of cloud storage utilities to assist with the management of files for cloud upload. Users of this library that set a duration for a SAS Uri with a value other than 1 hour may have generated a URL with a duration that is longer, or shorter than desired. Users not implemented SAS Uri's are unaffected. This issue was resolved in version 8.0.0 of the library.
