Programming in C# (55339)

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.

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.

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. 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’ll learn how to use interfaces and classes to define and create your own custom, reusable types. You’ll also learn how to create and use enumerable type-safe collections of any type.

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

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.

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).

In this module, you’ll learn how to use the request and response classes in the System.Net namespace to directly manipulate remote data sources. You’ll also learn about REST and OData and look briefly at ASP.NET Core MVC.

In this module, you’ll learn how to use Extensible Application Markup Language (XAML) and Windows Presentation Foundation (WPF) to create engaging UIs.

In this module, you’ll learn how to improve the performance of your applications by distributing your operations across multiple threads.

In this module, you’ll learn how to interoperate with unmanaged code in your applications and how to ensure that your code releases any unmanaged resources.

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. You’ll also learn how to generate code at runtime by using the Code Document Object Model (CodeDOM) and how manage your .NET assemblies.
