Description

This training will allow you, through simple and progressive examples, to familiarize yourself with the concepts of object-oriented programming (OOP) necessary for .NET development. You will learn the basics of using Visual Studio as well as how to structure an application into logical layers.

Who is this training for ?

For whom ?

Developers accustomed to procedural programming who want to move to OOP with .NET technologies.

Prerequisites

Training objectives

Understand the notion of object

Master common manipulations of objects in .NET
