C# was developed around 2000 by Microsoft as part of its .NET initiative and later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO (ISO/IEC 23270) in 2003. It was designed by Anders Hejlsberg, and its development team is currently led by Mads Torgersen, being one of the programming languages designed for the Common Language Infrastructure (CLI). The most recent version is 9.0, which was released in 2020 in .NET 5.0 and included in Visual Studio 2019 version 16.8.

Concept In Angular Day 14

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
