Microsoft.Extensions.DependencyInjection 9.0.0
About
Supports the dependency injection (DI) software design pattern which is a technique for achieving Inversion of Control (IoC) between classes and their dependencies.
Key Features
Provides an implementation of the DI interfaces found in the Microsoft.Extensions.DependencyInjection.Abstractions package.
How to Use
ServiceCollection services = new ();
services.AddSingleton<IMessageWriter, MessageWriter>();
using ServiceProvider provider = services.BuildServiceProvider();
// The code below, following the IoC pattern, is typically only aware of the IMessageWriter interface, not the implementation.
IMessageWriter messageWriter = provider.GetService<IMessageWriter>()!;
messageWriter.Write("Hello");
public interface IMessageWriter
{
void Write(string message);
}
internal class MessageWriter : IMessageWriter
{
public void Write(string message)
{
Console.WriteLine($"MessageWriter.Write(message: \"{message}\")");
}
}
