public void ConfigureServices(IServiceCollection services)
{
	services.Replace<IMyService, MyService>(ServiceLifetime.Scoped);
}

ReplaceTransient

Use ReplaceTransient to replace a service with a new implementation with a transient scope.

public void ConfigureServices(IServiceCollection services)
{
	services.ReplaceTransient<IMyService, MyService>();
}

ReplaceScoped

public void ConfigureServices(IServiceCollection services)

{
	services.RegisterOptions<MyOptions>(Configuration);
	services.RegisterOptions<MyOptions>(Configuration, "SectionName");
