کد بالا شامل موجودیت‌های Courses و Student است و کلاس‌های CourseDatabase و StudentDatabase به ترتیب برای ذخیره این موجودیت‌ها است.

قدم سوم :  بسته‌ی نیوگت Microsoft.AspNet.WebAPi.Cors را با استفاده از NuGet Package Manager، به منظور فعال سازی امکان صدا زدن این وب سرویس از دامنه‌های مختلف، به پروژه اضافه کرده و کد زیر را در کلاس WebApiCofig در پوشه App_Start قرار دهید.

config.EnableCors();

قدم چهارم : دو کنترل از نوع Web API 2 Empty را با نام‌های CourseAPIController و StudentAPIController ایجاد کرده و کدهای زیر را در آنها قرار دهید.

CourseAPIController.cs 

[EnableCors("*","*","*")]
public class CourseAPIController : ApiController
{
    [Route("Courses")]
    public IEnumerable<Courses> Get()
    {
        return new CourseDatabase();
    }
}

StudentAPIController.cs 

[EnableCors("*", "*", "*")]
public class StudentAPIController : ApiController
{
    [Route("Students")]
    public IEnumerable<Student> Get()
    {
        return new StudentDatabase();
    }
}

استفاده از Angular $q.all  

قدم اول : پروژه‌ی جدیدی را از نوع Empty ASP.NET در همین solution اضافه کرده و ارجاعات jQuery, Bootstrap و AngularJS را با استفاده از NuGet Package manager  مانند زیر اضافه کنید:

Install-Package jQuery
Install-Package bootstrap
Install-Package angularjs

قدم دوم : پوشه‌ایی را به نام MyScripts ایجاد کرده و درون آن فایل javascript  زیر را با نام logic.js اضافه کنید: 

var app = angular.module('mymodule', []);

//سرویسی برای بازگرداندن لیست دروس
app.service('courseService', function ($http) {
    this.get = function () {
        var response = $http.get("http://localhost:11696/Courses");
        return response;
    };
});

//سرویسی برای بازگرداندن لیست دانشجویان
app.service('studentService', function ($http) {
    this.get = function () {
        var response = $http.get("http://localhost:11696/Students");
        return response;
    };
});

//تعریف کنترلر
app.controller('ctrl', function ($scope, $q, courseService, studentService) {

    $scope.Courses = [];
    $scope.Students = [];
    loadData();

    /**/
    function loadData() {
        var promiseCourse = courseService.get();
        var promiseStudent = studentService.get();

        $scope.combineResult = $q.all([
            promiseCourse,
            promiseStudent
        ]).then(function (resp) {
            $scope.Courses = resp[0].data;
            $scope.Students = resp[1].data;
        });
    }
});
