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; is aimed at professional developers with at least one month of experience programming in an object-oriented environment. Those new to programming should consider course 55337AC - Introduction to Programming. Course 55337AC uses C# as a language to provide an introduction to general programming, while this course focuses on the C# language itself, making it an excellent follow-up course. If you want to learn how to get the most out of the C# language, this is the course for you.

Course outline

Module 1: C# Syntax
Microsoft .NET 6 provides a comprehensive development platform that you can use to create, deploy, and manage applications and services. Using .NET, you can create visually appealing applications, enable seamless communication across technological boundaries, and support 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'll also learn about some of the core C# constructs that allow you to get started developing .NET applications.

• Explain data types and expressions.
• Understand the constructions of the C# language

Module 2: C# language concepts
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-oriented language and uses the concept of methods to encapsulate logical units of functionality. Although it is good practice to have methods that do only one thing, they can be as simple or as complex as you want. It is also important to consider what happens to the state of your application when an exception occurs in a method.

Module 3: C# Structures, Collections and Events
To build effective applications, you must first learn some fundamental C# constructs. You must know how to create simple structures to represent the data elements you are working with.
