storage - How can I save some user data locally on my Xamarin Forms app? -

-

i have simple xamarin forms app. i've got simple poco object (eg. user instance or list of recent tweets or orders or whatever).

how can store object locally device? lets imagine serialize json.

also, how secure data? part of keychains, etc? auto backed up?

cheers!

you have couple options.

  1. sqlite. option cross-platform , works if have lot of data. added bonus of transaction support , async support well. edit: in past suggested using sqlite.net-pcl. due issues involving android 7.0 support (and apparent sunsetting of support) recommend making use of project forked from: sqlite-net
  2. local storage. there's great nuget supports cross-platform storage. more information see pclstorage
  3. there's application.current.properties implemented in xamarin.forms allow simple key-value pairs of data.

i think you'll have investigate , find out route serves needs best.

as far security, depends on put data on each device. android stores app data in secure app folder default (not secure if you're rooted). ios has several different folders data storage based on different needs. read more here: ios data storage

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.
