How would one receive a json object +[process with a dynamically loaded method /async task]
and then return the Json result back via http in asp.vNext?

It's a pretty common use case for an http server to be able to act as a json API... last night i cloned and browsed the source code of glimpse v2, to see how such a thing could be done (but there were way too many files and i didn't know which way was up) i google and i bing but i'm yet to see a small example that demonstrates such a thing in action.

for example here's how it could be done in 50 lines of javascript using dynamically loaded worker methods in •r:Ruby •v:JS •w:Clojure •x:Perl •y:Python •z:PHP

vx=require('vertx')
LOG=require('vertx/console').log
container=require('vertx/container')
DP=container.deployWorkerVerticle
l={a:LOG,j:JSON.stringify}
eb=vx.eventBus;
eb.registerHandler('godo',godo)
NUT={}
toolz={
fix:function(o){/*Ready o.[rx|rv|ry|rn] properties*/
if(typeof o.rx=='number'){o.rx=[o.rx.toString()]}
if(typeof o.rx=='string'){o.rx=o.rx.replace(/[\W\s]+$/,'').split('/');for(var i=0;i<o.rx.length;i++){if(/^-?\d+/.test(o.rx[i])){o.rx[i]=Number(o.rx[i])}}}
if(typeof o.rv=='undefined'){o.rv=''}
if(typeof o.ry=='undefined'){o.ry=[]}
if(typeof o.rn=='undefined'){o.rn=0}
if(o.cb){/*jsonp*/o.rb=-3}
if((''+o.rx[0]).charAt(0)=='~'){o.rb='-'+o.rx[0].substr(1);o.rx.shift()}else if(!o.rb){o.rb=o.all?-2:-1}
}
}
var N=0

function godo(o,cb){/*Run o thru one or more verticles*/
LOG(o.rn+' von.js received: ' + l.j(o));o.rb=++N
NUT[o.rb]=(function(cb){return function(o){cb(o)}})(cb)
toolz.fix(o)
DoNext(o)
} 

function DoNext(o){LOG(o.rn)
if(o.rn!=0){o.e=o.rv}
if(o.rn>=o.rx.length){LOG('returning: ' + l.j(o));NUT[o.rb](o);/*delete NUT[o.rb]*/;return}
var ns=''+o.rx[o.rn];var s=ns.charAt(0);var n=parseInt(ns.substr(1))
LOG(o.rn+'/'+o.rx.length+' ~ '+ns+'['+n+']'+s)
o.rn+=1;
var ext=({r:'rb',v:'js',w:'clj',x:'pl',y:'py',z:'php'})[s]
LOG('EXT:'+ext)
if(!ext){NUT[o.rb](o);delete NUT[o.rb];return}
if(s=='v' && n==3){var RV='fail';try{eval('RV=('+o.e+')')}catch(er){RV=er.message};LOG(RV);o.rv=RV;return DoNext(o);}
if(NUT[ns]){LOG(ns+' already loaded');return eb.send(ns,o,DoNext)}
var fpr='../../../../2/'+s+s+'/Ax/'+n+'/'+s+'.'+ext;LOG('ns:'+ns);LOG('ns:'+fpr)
container.deployVerticle(fpr,null,1,function(){NUT[ns]=true;eb.send(ns,o,DoNext)})
}

web1=vx.createHttpServer()
sox=vx.createSockJSServer(web1)
sox.bridge({prefix:'/eventbus'},[{}],[{}])
web1.listen(1422)

this is the same question as: #770
except that one shows "Powershell Listening on http://127.0.0.1:1416..."
