How to measure render time in Javascript (IE 11)? -


i have small canvas animation i'd measure render time in javascript. got following result ie 11 dev tool:

screenshot below performance

in time interval 0-7,5 sec animation not in viewport, there no rendering process visible (purple on screenshot). in interval 7,5-end, when animation in viewport, changed. i'd measure. don't these results if try measure time following:

var t0 = performance.now(); render(); var t1 = performance.now(); console.log(t1 - t0);

is there way detect rendering process same results shown on screenshot?

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
