6) What does ConfigureService and Configure in Startup.cs ?

  • The Startup.cs file is executed after program.cs file. 

  • The Startup.cs file is used for registering services and injection of modules in HTTP pipelines.

  • The ConfugureService method gets call before Configure method.

  • The ConfigureServices method is used to add services in DI(Dependency Injection) container.

  1. User requests are intercepted by Controller whether it is a URL request or any event raised by the user on the page.

Lecture 14 : Concept In Angular What is ngModel : ngModel is Angular’s answer to the two-way data binding problem. Previously in AngularJS, there was no way to perform a binding which would update automatically. What are Directives : Directives are markers on a DOM element that tell AngularJS to attach a specified behaviour to that DOM element or even transform the DOM element and its children. Angular includes various built-in directives. In addition to this, you can create custom directives for your application. ng-model Directive : The ng-model directive binds the value of HTML controls (input, select, textarea) to application data. With the ng-model directive you can bind the value of an input field to a variable created in AngularJS. Two-Way Binding : The binding goes both ways. If the user changes the value inside the input field. Two-way binding, we can display a data property as well as an update that property when the user makes changes. Two-way binding
