Learn C# Programming

Overview of this book

The C# programming language is often developers’ primary choice for creating a wide range of applications for desktop, cloud, and mobile. In nearly two decades of its existence, C# has evolved from a general-purpose, object-oriented language to a multi-paradigm language with impressive features. This book will take you through C# from the ground up in a step-by-step manner. You'll start with the building blocks of C#, which include basic data types, variables, strings, arrays, operators, control statements, and loops. Once comfortable with the basics, you'll then progress to learning object-oriented programming concepts such as classes and structures, objects, interfaces, and abstraction. Generics, functional programming, dynamic, and asynchronous programming are covered in detail. This book also takes you through regular expressions, reflection, memory management, pattern matching, exceptions, and many other advanced topics. As you advance, you'll explore the .NET Core 3 framework and learn how to use the dotnet command-line interface (CLI), consume NuGet packages, develop for Linux, and migrate apps built with .NET Framework. Finally, you'll understand how to run unit tests with the Microsoft unit testing frameworks available in Visual Studio. By the end of this book, you’ll be well-versed with the essentials of the C# language and be ready to start creating apps with it.

Dynamically loading assemblies

The reflection services allow you to load an assembly at runtime. This is done using the System.Reflection.Assembly type, which provides various methods for loading assemblies.

Assemblies can be either public (also called shared) or private. A shared assembly is intended to be used by several applications and is usually located under the Global Assembly Cache (GAC), a system repository for assemblies. A private assembly is intended to be used by a single application and is stored in the application directory or one of its sub-directories. Shared assemblies must be strongly named and enforce version constraints; these requirements are not necessary for private assemblies.

An assembly can be loaded in one of three contexts or without any:

  • The load context, which contains assemblies loaded from the GAC, the application directory (ApplicationBase of the app domain), or its sub-directories of private assemblies (PrivateBinPath of the app domain...
