javascript - AngularJS Service Undefined: Unknown provider: $scopeProvider <- $scope -

-

i've started learning angular js , i'm having problem injecting service controller. i'm trying put threadfactory service threadcontroller, i'm getting undefined error when calling it. advice great. error i'm getting is:

unknown provider: $scopeprovider <- $scope <- threadservice

app.js

angular.module('threadsapp', ['ngroute']); angular.module('threadsapp')     .config(function ($routeprovider, $locationprovider) {         $routeprovider             .when('/', {                 templateurl: 'views/index.html',             })             .when('/selected/:topicname', {                 templateurl: 'views/threads.html',                 controller: 'threadcontroller',             })             .otherwise({                 redirectto: "/"             });             $locationprovider.html5mode(true);     });

threadcontroller.js

angular.module('threadsapp').controller("threadcontroller",     ["$scope", "$route", "$routeparams", "threadservice", function ($scope, $route, $routeparams, threadservice) {     $scope.test = "hello!";     $scope.test2 = threadservice.get(); }]);

threadservice.js

angular.module('threadsapp').service("threadservice", ["$scope", function ($scope) {     return {         get: function() {             return "hello";         }     } }]);

order of imports

    <script src="bower_components/jquery/dist/jquery.js"></script>     <script src="bower_components/angular/angular.js"></script>     <script src="bower_components/angular-route/angular-route.js"></script>     <script src="bower_components/bootstrap/dist/js/bootstrap.js"></script>     <script src="components/app.js"></script>     <script src="components/bodycontroller.js"></script>     <script src="components/topiccontroller.js"></script>     <script src="components/threadservice.js"></script>     <script src="components/threadcontroller.js"></script>

you can't inject $scope threadservice way you're trying to. $scope isn't typical service when inject controller. if remove $scope injection threadservice.js, bet error go away.

in interest of not being redundant, fuller explanation can found here:

injecting $scope angular service function()

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
