does xamarin.forms have built-in ioc navigation service? mean prism, register routes. if yes - documentation? if not - xamarin.forms have built-in navigation service in near future? also - if not - best mvvm fw xamarin.android, xamarin.ios, xamarin.winxyz , xamarin.forms? , why? it seems me comes down battle between prism , freshmvvm - brings me important questions: which of these 2 performing better? (which 1 faster?) which of these more lead way of mvvm frameworks considering mobile development in future? no xamarin forms not offer navigation prism. had goal of making built in navigation similar prism, has since disappeared roadmap. there no direct ioc concept built directly xamarin forms. if developing native ui's prism isn't purpose built xamarin forms. in case might should @ mvvmcross. battle tested in lot of classic xamarin apps. if developing xamarin forms, prism best use. opinion may biased, it's public opinion of many of on xamarin tea...

i have java program reads json files have attributes these: "property": { "value1": 4.35684302507939 } in actual program, "property" double array, , contains fixed amount of values. format of json file fixed, , have write json files conform it. there way, can serialize double array, looks in code example? easiest way think this, create class property , serialize that, i'd avoid it. json file doesn't contain value, several others. thought, maybe can create jsonobject out of array, don't know how can have serialized in right place. ex. "name" : "bob" "age" : "13" "property": { "value1": 4.35684302507939 } instead of "name" : "bob" "property": { value1": 4.35684302507939 } "age" : "13" every appreciated.
