About the Course

55339A is the equivalent of the retired MOC Course 20483CC - Programming in C#. This five-day training course teaches developers the programming skills that are required to create applications using the C# language. During their five days in the classroom, students review the basics of C# program structure, language syntax, and implementation details, and then consolidate their knowledge throughout the week as they build an application that incorporates several features of .NET. The course aims to follow the spirit of the Microsoft Official Curriculum course 20483, while bringing it completely up-to-date with the latest features of C#, .NET 6.0 and Visual Studio 2022.

Overview

About This Course

This five day training course teaches developers the programming skills that are required for developers to create Windows applications using the C# language. During their five days in the classroom students review the basics of C# program structure, language syntax, and implementation details, and then consolidate their knowledge throughout the week as they build an application that incorporates several features of the .NET 6.0.

Audience Profile

This course is intended for experienced developers who already have programming experience in C, C++, JavaScript, Objective-C, Microsoft Visual Basic, or Java and understand the concepts of object-oriented programming. This course is not designed for students who are new to programming; it is targeted at professional developers with at least one month of experience programming in an object-oriented environment.

Course Outline

Module 1: Review of C# Syntax

Microsoft .NET 6.0 provides a comprehensive development platform that you can use to build, deploy, and manage applications and services. By using .NET, you can create visually compelling applications, enable seamless communication across technology boundaries, and provide support for a wide range of business processes.

In this module, you will learn about some of the core features provided by.NET and Microsoft Visual Studio. You will also learn about some of the core C# constructs that enable you to start developing .NET applications.

Module 2: Creating Methods, Handling Exceptions, and Monitoring Applications

Applications often consist of logical units of functionality that perform specific functions, such as providing access to data or triggering some logical processing. C# is an object-orientated language and uses the concept of methods to encapsulate logical units of functionality. Although a good practice is to have methods that do just one thing, they can be as simple or as complex as you like. It is also important to consider what happens to the state of your application when an exception occurs in a method.

In this module, you will learn how to create and use methods and how to handle exceptions. You will also learn how to use logging and tracing to record the details of any exceptions that occur. After completing this module, students will be able to:
