IHttpContextAccessor is an interface and the term "singleton" does not apply to it as such. In the definition of the interface IHttpContextAccessor I can't see anything about holding the user name or similar. It only has one property, which should be implemented to return the current HttpContext. So one way of doing it should be that revision listener does something like On call to NewRevision(): var user = _httpContextAccessor.HttpContext.User; I'm sure there are other way to do it too. /Oskar > > > On Tue, Nov 13, 2018 at 3:51 AM Roger Kratz <roger.kr...@teleopti.com> > wrote: > >> Yes, IRevisionListener supports DI. >> >> >> >> var myListener = new MyRevisionListener(new DepA(), new DepB(new DepC())) >> >> >> >> https://nhibernate.jira.com/browse/NHE-17 >> >> >> >> >> >> >> >> *From:* nhusers@googlegroups.com <nhusers@googlegroups.com> *On Behalf >> Of *Pratip Bagchi >> *Sent:* den 12 november 2018 18:43 >> *To:* nhusers <nhusers@googlegroups.com> >> *Subject:* [nhusers] Add auditing through Http >> >> >> >> I am in dire need of your help.
