20483 Programming in C#

Course Description

This training course teaches developers the programming skills that are required for developers to create Windows applications using the C# language.

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.

Prerequisite(s) Recommended

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.

Learning Objectives

After completing this course, students will be able to:

• Describe the core syntax and features of C#.
• Create and call methods, catch and handle exceptions, and describe the monitoring requirements of large-scale applications.
• 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, extend a .NET Framework class, and create generic classes and methods.
• Read and write data by using file input/output and streams, and serialize and deserialize data in different formats.
• Create and use an entity data model for accessing a database and use LINQ to query and update data.
• Use the types in the System.Net namespace and WCF Data Services to access and query remote data.
• Build a graphical user interface by using XAML.
• Improve the throughput and response time of applications by using tasks and asynchronous operations.
• Integrate unmanaged libraries and dynamic components into a 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.
