Programming in C# (55339)

During their five days in the classroom, students review the basics of 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 .NET. The course aims to follow the spirit of the Microsoft Official Curriculum course 20483, while bringing it completely up-to-date with the latest features of C#, .NET 6.0 and Visual Studio 2022.

Module 1: C# Syntax

Microsoft .NET 6 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 ll learn about some of the core features provided by.NET and Microsoft Visual Studio. You ll also learn about some of the core C# constructs that enable you to start developing .NET applications.

Module 2: C# Language Concepts

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 ll learn how to create and use methods and how to handle exceptions. You ll also learn how to use logging and tracing to record the details of any exceptions that occur

Module 3: C# Structures, Collections and Events

To create effective applications you must first learn some fundamental C# constructs. You need to know how to create simple structures to represent the data items you are working with.

Lessons

• Lesson 1: Creating Classes
• Lesson 2: Interfaces
• Lesson 3: Understanding Generics in C#

After completing this module, students will be able to:

• Use interfaces and classes to define and create custom, reusable types
• Create and use enumerable type-safe collections of any type

Module 5: C# Inheritance

In this module, you ll learn how to use inheritance to create class hierarchies and to extend .NET types.

Lessons

• Lesson 1: Hierarchies of Classes
• Lesson 2: Polymorphism
• Lesson 3: Extending Classes

After completing this module, students will be able to:

• Use inheritance to factor common functionality into a base class.
• Implement polymorphism by using an abstract method.
• Create a custom exception class.

Module 6: Input and Output

In this module, you ll learn how to read and write data by using transactional filesystem I/O operations, how to serialize and deserialize data to the filesystem, and how to read and write data to the filesystem by using streams.

Lessons

• Lesson 1: File I/O
• Lesson 2: Serialization and Deserialization
• Lesson 3: Streams

After completing this module, students will be able to:

• Read and write data by using transaction filesystem I/O operations
• How to searlize and deserialize data to the file system
• How to read and write data to the filesystem by using streams.

Module 7: Database Access

In this module, you ll learn how to use Entity Framework and how to query many types of data by using Language-Integrated Query (LINQ).

Lessons

• Lesson 1: Entity Framework
• Lesson 2: LINQ

After completing this module, students will be able to:

• Use entity Framework
• Learn how to query many types of data by using Language-Integrated Query (LINQ).

Module 8: Using the Network

Lessons

• Lesson 1: Web Services
• Lesson 2: REST and OData
• Lesson 3: ASP.NET Core MVC

After completing this module, students will be able to:

• Send data to remote web services.
• Access remote data over web services.
• Understand REST and OData.

Module 9: Graphical User Interfaces

Lessons

• Lesson 1: Dynamic Objects
• Lesson 2: Managing Resources

After completing this module, students will be able to:

• Interoperate with unmanaged code in applications.
• Ensure that code releases any unmanaged resources.

Module 12: Designing for Reuse

In this module, you ll learn how to consume existing assemblies by using reflection, and how to add additional metadata to types and type members by using attributes.

Lessons

• Lesson 1: Metadata
• Lesson 2: Attributes
• Lesson 3: Generating Code
• Lesson 4: Assemblies

After completing this module, students will be able to:

• Consume existing assemblies by using .NET reflection.
• Add additional metadata to types and type members using attributes.
• Create custom attributes.
• Get information about assemblies.

• For students who don t have prior experience of programming in a high-level language, it is recommended that they take the 55337AC course, which uses C# as the language to facilitate an introduction to programming.
• Course 55339AC focuses on the C# language itself, making it an excellent follow-on course.

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. Those new to programming should consider course 55337AC - Introduction to Programming. The 55337AC course uses C# as the language to facilitate an introduction to programming generally, whereas this course focuses on the C# language itself, making it an excellent follow-on course. If you want to learn to take full advantage of the C# language, then this is the course for you.
