Activators in .NET are classes or methods that create instances of other classes. They are essentially responsible for instantiating objects, configuring them, and returning them for use in an application. Activators are often used in conjunction with dependency injection containers, which manage the creation and lifetime of objects.
IPlugin plugin = (IPlugin)Activator.CreateInstance(type); plugins.Add(plugin);
return plugins;

public class Configuration public string ConnectionString get; public Configuration(string connectionString) ConnectionString = connectionString; // Instantiation with arguments Type configType = typeof(Configuration); object[] ctorArgs = "Server=myServerAddress;Database=myDataBase;" ; Configuration config = (Configuration)Activator.CreateInstance(configType, ctorArgs); Use code with caution.

A major shift during the .NET 4.6.1 era was the introduction of . activators dotnet 4.6.1
Internally, many DI containers use Activator.CreateInstance to generate object instances.
class remains a core component of the .NET ecosystem for developers maintaining legacy systems. Microsoft Learn What is the .NET Activator?

Understanding Activators in .NET 4.6.1: A Comprehensive Guide
In .NET 4.6.1, you can create generic types by first constructing a closed generic type at runtime.
