i'm not sure if don't big picture or if miss benefits of parsing json-string dynamic object? if have class this class product { public string name { get; set; } public double price { get; set; } public string category { get; set; } } and use httpclient object this product product = await response.content.readasasync<product>(); what benefit code? string content = await response.content.readasstringasync(); dynamic product = jobject.parse(content); if want use them need write product.name with typed apporach @ least have intellisense. if service changes product dynamic approach doesn't me either because still need access mentioned above. so missing? why should use dynamics or when? you always prefer use strong type on dynamic (performance\convenience). here cases use dynamic: when want parse xml , dont want work xelement's, xpath's etc. com interop - makes things easy , nice (try working excel\word , convinced...

i having issue in application. whenever browser refreshes reassign cookie new content , new session id. right behavior of browser? the application uses express , connect-tedious libraries of nodejs. user gets logged out because cookie content , session id different whenever refresh. suggestion on how go resolving problem? if node server code responsible setting cookies user , session (using set-cookie header or generating javascript file client same), should check existing cookies in request. when page reloaded, request come server again. @ point can read cookies passed server (which include cookie session , user set last time). if these cookies found , valid, server should not generate new cookie same. even if logic not reside on server , part of client side js, overall idea same. not create new cookies, if can read existing ones correctly.

sencha command let create, build , distribute own package. ext js library built using sencha command. i wonder correct way have built-package have in correct order, list of singleton files in root folder , there no dependency among each other. example, sencha core package, there ext.js, componentquery.js, etc., how sencha command knows build ext.js first. this bit puzzling me. have similar situation. have package, let's call mycoolstuff, in root source folder, have coolstuff.js , list of singleton/utility files, example, coolstuffeventhandler.js. absolutely need coolstuff.js built first, far have no luck. how did ext js it? when define classes, no matter singletones or not, specify dependencies using requires , uses directives: ext.define('coolstuffeventhandler', { //// requires: [ 'coolstuff' ], ///// }); that's all! rest taken care of sencha cmd you.
