📘 20483: Programming in C# Outline

The Microsoft .NET Framework version 4.7 provides a comprehensive development platform that you can use to build, deploy, and manage applications and services. By using the .NET Framework, 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 the .NET Framework and Microsoft Visual Studio. You will also learn about some of the core Visual C# constructs that enable you to start developing .NET Framework applications.

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

Lab: Implementing Edit Functionality for the Students List

Implementing Insert Functionality for the Students List
Implementing Delete 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 2017 and Visual C# provide.
Use basic Visual C# data types, operators, and expressions.
Use standard Visual C# constructs.

Applications often consist of logical units of functionality that perform specific functions, such as providing access to data or triggering some logical processing. Visual C# is an object-orientated language and uses the concept of methods to encapsulate logical units of functionality. A method can be as simple or as complex as you like, and therefore it is 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.

Creating and Invoking Methods
Creating Overloaded Methods and Using Optional and Output Parameters
Handling Exceptions
Monitoring Applications

Lab: Extending the Class Enrolment Application Functionality

Refactoring the Enrolment Code
Validating Student Information
Saving Changes to the Class List

After completing this module, students will be able to:

Create and invoke methods.
Create overloaded methods and use optional parameters.
Handle exceptions.
Monitor applications by using logging, tracing, and profiling

To create effective applications by using Windows Presentation Foundation (WPF) or other .NET Framework platforms, you must first learn some basic Visual C# constructs. You need to know how to create simple structures to represent the data items you are working with. You need to know how to organize these structures into collections, so that you can add items, retrieve items, and iterate over your items. Finally, you need to know how to subscribe to events so that you can respond to the actions of your users. In this module, you will learn how to create and use structs and enums, organize data into collections, and create and subscribe to events.

Implementing Structs and Enums
Organizing Data into Collections
Handling Events

Lab: Writing the Code for the Grades Prototype Application

Adding Navigation Logic to the Grades Prototype Application
Creating Data Types to Store User and Grade Information
Displaying User and Grade Information

After completing this module, students will be able to:

Create and use structs and enums.
Use collection classes to organize data.
Create and subscribe to events.

In this module, you will learn how to use interfaces and classes to define and create your own custom, reusable types. You will also learn how to create and use enumerable, type-safe collections of any type.

Creating Classes
Defining and Implementing Interfaces
Implementing Type-Safe Collections

Lab: Adding Data Validation and Type-Safety to the Application

Implementing the Teacher, Student, and Grade Structs as Classes
Adding Data Validation to the Grade Class
Displaying Students in Name Order
Enabling Teachers to Modify Class and Grade Data
