What is a .NET Core module?

In .NET Core, a module is a self-contained unit of functionality that can be added to an application at runtime. A module is typically implemented as a dynamic link library (DLL) that contains one or more classes and can be loaded and executed by the .NET Core runtime.


Modules provide a way to extend the functionality of an application without having to modify its source code. They can be used to add new features, implement plugins, or customize the behavior of an application based on user preferences or other runtime conditions.


Modules can be loaded dynamically at runtime using the Assembly.Load method or other reflection APIs provided by .NET Core. Once loaded, a module's classes and methods can be invoked just like any other .NET Core code.


.NET Core supports several mechanisms for creating and distributing modules, including NuGet packages, class libraries, and runtime-specific extensions. Modules can be written in any .NET Core-compatible language, including C#, VB.NET, and F#.


Overall, modules provide a flexible and powerful way to extend and customize .NET Core applications, making them more adaptable and versatile for a variety of use cases.
