windows runtime - C#/XAML - DispatcherTimer resolution -

-

i'm writing windows 10 universal app in c#/xaml.

i make use of dispatchertimer class, , i'm wondering what's resolution. i'm doing tests in desktop environment - when set set interval property value less 33 milliseconds seems not affect timer - tick event still fires if interval set 33 miliseconds (around 33 times per second).

is behaviour design (you can't fire dispatchertimer more 33 times per second) or depend on app's working environment - device/processor/memory etc. - , environment doesn't support higher timer resolution?

although cannot find official documentation anywhere, observing seems make sense. 33 times per second around 30 fps default windows phone 8.1. great know why need such high resolution? check: wpf timer problem… cannot correct millisecond tick

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
