let's take simple case .net smtpclient, can following (ignoring credentials, ssl , exception handling): async task sendmail() { var m = new mailmessage(...); var s = new smtpclient(host, port); s.sendcompleted += (s, e) => { m.dispose(); s.dispose(); }; await s.sendmailasync(m); } all fine; func dispose()ing called whenever async sending finishes. m , s within containing scope declared, no problem there. but had following: smtpclient setupmailclient(mailmessage mail) { var smtpclient = new smtpclient(host, port); smtpclient.sendcompleted += (s, e) => { mail.dispose(); smtpclient.dispose(); }; return smtpclient; } async task sendmail() { var m = new mailmessage(...); var s = setupmailclient(m); await s.sendmailasync(m); } now, calling await sendmail() still safe? closure still valid? pass in reference mailmessage 'mail' - copy of reference, valid in context of setupmailclient(). overthinking it, or still safe...

this question has answer here: why should interface java class preferred? 9 answers what difference between these 2 initialization of list : list<integer> aa = new arraylist<>(); arraylist<integer> aaa = new arraylist<>(); polymorphism the first uses polymorphism assign object reference variable type interface list . preferable. in oop, practice assign objects variables of general superclass or interface. if calling code needs methods defined part of list , , not additional methods defined in arraylist , go list . this gives code freedom switch different implementation of list , class other arraylist , without breaking calling code. this basic java 101 concept should mastered sooner rather later on java education.
