Changing kestrel's port from localhost:5000 to azure server?

Currently when I deploy my app to azure then I will get below error

System.AggregateException: One or more errors occurred. --->
    System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

I am using the following:

var host = new WebHostBuilder()
  .UseKestrel()
  .UseUrls("azure_server_url")                                           
  .UseContentRoot(Directory.GetCurrentDirectory())
  .UseIISIntegration()
  .UseStartup<Startup>()
  //.UseConfiguration(configuration)
  .Build();

host.Run();
