c# - How to manage NHibernate sessions when using Repositories/Transactions -

i'm getting stuck nhibernate @ moment , i'm trying work out how best correctly design repositories whilst correctly managing lifetime of session. from examples i've seen, seems common practise inject isession each of repositories follows: public class somerepository : irepository { private readonly isession _session; public somerepository(isession session) { _session = session; } public ilist<t> loadsomedata() { return _session.query<t>().where(...).tolist(); } } so fine, can see couple of cases there problems: 1) there may not 1 session lifetime of app. 2) when accessing nhibernate should wrap our calls in transaction - if transaction faults must rollback transaction , close session. in both these cases repository defunct references closed session. my particular application long running process, call nhibernate, expect high turnover sessions instead of keeping 1 session open lifetime of app. i th...
