Programming in C# - 20483 Course Outline
This training course teaches developers the programming skills that are required for developers to create Windows applications using the Visual C# language. During their five days in the classroom students review the basics of Visual 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 Framework 4.7.
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.
Developers attending this course should already have gained some limited experience using C# to complete basic programming tasks. More specifically, students should have hands-on experience using C# that demonstrates their understanding of the following:
How to name, declare, initialize and assign values to variables within an application.
How to use: arithmetic operators to perform arithmetic calculations involving one or more variables; relational operators to test the relationship between two variables or expressions; logical operators to combine expressions that contain relational operators.
How to create the code syntax for simple programming statements using C# language keywords and recognize syntax errors using the Visual Studio IDE.
How to create a simple branching structure using an IF statement.
How to create a simple looping structure using a For statement to iterate through a data array.
How to use the Visual Studio IDE to locate simple logic errors.
How to create a Function that accepts arguments (parameters and returns a value of a specified type.
How to design and build a simple user interface using standard controls from the Visual Studio toolbox.
How to connect to a SQL Server database and the basics of how to retrieve and store data.
How to sort data in a loop.
How to recognize the classes and methods used in a program.
At course completion
After completing this course, students will be able to:
Describe the core syntax and features of Visual C#.
Create methods, handle exceptions, and describe the monitoring requirements of large-scale applications.

Module 1: Review of Visual C# Syntax
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.

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. 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.

Module 3: Basic types and constructs of Visual C#
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.
