c# - Api Exception filters for autofac -


i have configured webapi iautofacexceptionfilter exception details. registered things in autofac.config

httpconfiguration config = serviceconfig.initialize(new configbuilder(options, (configuration, builder) => {          builder.registertype<errorloggingexceptionfilter>()        .aswebapiexceptionfilterfor<basecontroller>()        .instanceperapirequest();         builder.registerwebapifilterprovider(globalconfiguration.configuration);        //builder.registertype<errorloggingexceptionfilter>()        //.aswebapiexceptionfilterfor<basecontroller>().singleinstance();         builder.overridewebapiactionfilterfor<basecontroller>();        builder.registersource(        new anyconcretetypenotalreadyregisteredsource(t =>           !(t.isgenerictype && t.getgenerictypedefinition() == typeof(meta<>))     )); }  var serviceresolver = (autofacwebapidependencyresolver)config.dependencyresolver;

but gives me error

the autofacwebapidependencyresolver must configured dependency resolver web api before autofaccontrollerconfigurationattribute can resolve services container controller type.

you should make autofacwebapidependencyresolver default web api dependency resolver :

// set dependency resolver autofac. var builder = new containerbuilder(); var container = builder.build(); config.dependencyresolver = new autofacwebapidependencyresolver(container);

see autofac documentation more info.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
