55339: Programming in C# Training

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.

Lessons

• Overview of Writing Application by Using C#
• Data Types, Operators, and Expressions
• C# Programming Language Constructs

Lab 1: Implementing Edit Functionality for the Students List

After completing this module, students will be able to:

• Describe the architecture of .NET Framework applications and the features that Visual Studio 2022 and C# provide.
• Use basic C# data types, operators, and expressions.

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.
