Create A Class




public interface IDependency {
    void Display();
}

public class DependencyClass : IDependency {
    public void Display() {
        Console.WriteLine("Display Function Called");
    }
}



Create An Implementation Class




public class ImplementationClass {
    public IDependency Dependency { get; set; }

    public void WrapperDisplay() {
        Dependency.Display();
    }
}



Call The Implementation Class


// Create a new service collection
var services = new ServiceCollection();

// Configure the services
services.AddTransient<IDependency, DependencyClass>();
services.AddTransient<ImplementationClass>();

// Build the service provider
var serviceProvider = services.BuildServiceProvider();

// Resolve the ImplementationClass instance from the service provider
var implementation = serviceProvider.GetService<ImplementationClass>();
DependencyClass obj = new DependencyClass();
            
implementation.Dependency = obj;

implementation.WrapperDisplay();
Console.ReadLine();
