this.next = next;
}
public async Task Invoke(HttpContext context) {
await this.next.Invoke(context);
}
}
app.UseMiddleware<SampleMiddleware>();

services)
{
service.AddMvc();
}
{
app.UseMvc(routes => ...)

builder.Populate(services);
return builder.Build().Resolve<IServiceProvider>();
}

public void ConfigureServices(IServiceCollection services)
{
services.AddScoped<ICalculator, Calculator>();
}
