Programming in C# - M20483-DV Course Outline

(5 Days) - Learning Credits Accepted

Overview

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.

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.

Prerequisites

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-scaleapplications.
• Implement the basic structure and essential elements of a typical desktop application.
• Create classes, define and implement interfaces, and create and use generic collections.
• Use inheritance to create a class hierarchy and to extend a .NET Framework class.
• Read and write data by using file input/output and streams, and serialize and deserialize data indifferent formats.
• Create and use an entity data model for accessing a database and use LINQ to query data.
• Access and query remote data by using the types in the System.Net namespace and WCF DataServices.
• Build a graphical user interface by using XAML.
• Improve the throughput and response time of applications by using tasks and asynchronousoperations.
• Integrate unmanaged libraries and dynamic components into a Visual C# application.
• Examine the metadata of types by using reflection, create and use custom attributes, generate code at runtime, and manage assembly versions.
• Encrypt and decrypt data by using symmetric and asymmetric encryption.

Course Outline

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.

Lesson

  • 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
  • Displaying a Student’s Age

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.

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.

Lesson

  • 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

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.
