    Windows Phone上的新Windows 10会是什么样子？现在我们就来看看！
    1.邮件    如题图所示，作为改进最大的自带应用，微软试图搭建一个跨、平板和PC的Outlook应用，从现在的效果来看，Windows 10的确比Windows 8和Windows Phone 8.1做得要好很多。不仅加入了"插入图标"、"全文格式化"等功能，同时用户还可以使用手势功能进行删除等操作。
    开始界面
    开始界面也变得更自然了，虽然整体明显借鉴了Android和iOS壁纸的管理方式。
    Messaging功能
    该提升对于那些喜欢通过视频聊天的人来说无疑是一个再好不过的消息，Windows 10将Skype功能和Windows Phone连接在一起。你可以随意地在同一个页面下切换SMS与Skype。同时网页上会有内联推送通知，方便你及时回复。推送通知同时和PC端相连，当你忽略了PC上的APP推送消息时，它同样会从手机上自动消失。
    拍照功能
    手机、PC和平板三端都对照片应用实现了同步，用户可通过OneDrive实时共享。自带Lumia Camera界面操作清晰易懂，可快速抓拍、摄影，对图片的编辑功能也更丰富，PC上的使用效果更佳。
    日历方面的提升也很明显，实现了Gmail对三端、IMAP、POP及其它web邮箱服务的支持。
    地图
    还在抱怨要么是HERE地图要么是Bing Maps地图吗？Windows 10的出现会改变这一切。除了统一的地图功能，Cortana语音助手也会自动加入其中。

出门在外也不愁ASP.NET MVC 4 Dependency Injection | The ASP.NET Site
Follow us on
ASP.NET MVC 4 Dependency InjectionNote: This Hands-on Lab assumes you have basic knowledge of ASP.NET MVC and ASP.NET MVC 4
filters. If you have not used ASP.NET MVC 4 filters before, we recommend you to go over ASP.NET MVC Custom
Action Filters Hands-on Lab.
All sample code and snippets are included in the Web Camps Training Kit, available at .In Object Oriented Programming paradigm, objects work together in a collaboration model where there are contributors and
consumers. Naturally, this communication model generates dependencies between objects and components, becoming difficult to manage when
complexity increases.
Class dependencies and model complexity
You have probably heard about the Factory Pattern and the separation between the interface and the implementation using
services, where the client objects are often responsible for service location.
The Dependency Injection pattern is a particular implementation of Inversion of Control. Inversion of Control (IoC) means
that objects do not create other objects on which they rely to do their work. Instead, they get the objects that they need from an outside
source (for example, an xml configuration file).
Dependency Injection (DI) means that this is done without the object intervention, usually by a framework component that
passes constructor parameters and set properties.
The Dependency Injection (DI) Design Pattern
At a high level, the goal of Dependency Injection is that a client class (e.g. the golfer) needs something that satisfies an
interface (e.g. IClub). It doesn't care what the concrete type is
(e.g. WoodClub, IronClub, WedgeClub or
PutterClub), it wants someone else to handle that (e.g. a good caddy). The Dependency Resolver in ASP.NET MVC can allow you
to register your dependency logic somewhere else (e.g. a container or a bag of clubs).
Dependency Injection - Golf analogy
The advantages of using Dependency Injection pattern and Inversion of Control are the following:
Reduces class coupling
Increases code reusing
Improves code maintainability
Improves application testing
Note: Dependency Injection is sometimes compared with Abstract Factory Design Pattern, but there is a slight difference
between both approaches. DI has a Framework working behind to solve dependencies by calling the factories and the registered services.
Now that you understand the Dependency Injection Pattern, you will learn throughout this lab how to apply it in ASP.NET MVC 4. You will
start using Dependency Injection in the Controllers to include a database access service. Next, you will apply Dependency
Injection to the Views to consume a service and show information. Finally, you will extend the DI to ASP.NET MVC 4 Filters,
injecting a custom action filter in the solution.
In this Hands-on Lab, you will learn how to:
Integrate ASP.NET MVC 4 with Unity for Dependency Injection using NuGet Packages
Use Dependency Injection inside an ASP.NET MVC Controller
Use Dependency Injection inside an ASP.NET MVC View
Use Dependency Injection inside an ASP.NET MVC Action Filter
Note: This Lab is using Unity.Mvc3 NuGet Package for dependency resolution, but it is possible to adapt any Dependency
Injection Framework to work with ASP.NET MVC 4.
Prerequisites
You must have the following items to complete this lab:
or superior (read
for instructions on how to install it).
Installing Code Snippets
For convenience, much of the code you will be managing along this lab is available as Visual Studio code snippets. To install the code
snippets run .\Source\Setup\CodeSnippets.vsi file.
If you are not familiar with the Visual Studio Code Snippets, and want to learn how to use them, you can refer to the appendix from this
document &&.
This Hands-On Lab is comprised by the following exercises:
Note: Each exercise is accompanied by an End folder containing the resulting solution you should obtain
after completing the exercises. You can use this solution as a guide if you need additional help working through the exercises.
Estimated time to complete this lab: 30 minutes.
Exercise 1: Injecting a Controller
In this exercise, you will learn how to use Dependency Injection in ASP.NET MVC Controllers by integrating Unity using a NuGet Package. For
that reason, you will include services into your MvcMusicStore controllers to separate the logic from the data access. The services will create
a new dependence in the controller constructor, which will be resolved using Dependency Injection with the help of Unity.
This approach will show you how to generate less coupled applications, which are more flexible and easier to maintain and test. You will
also learn how to integrate ASP.NET MVC with Unity.
About StoreManager Service
The MVC Music Store provided in the begin solution now includes a service that manages the Store Controller data named
StoreService. Below you will find the Store Service implementation. Note that all the methods return Model entities.
C#namespace MvcMusicStore.Controllers
using System.Web.M
using MvcMusicStore.F
using MvcMusicStore.S
[MyNewCustomActionFilter(Order = 1)]
[CustomActionFilter(Order = 2)]
public class StoreController : Controller
private IStoreS
public StoreController(IStoreService service)
this.service =
// GET: /Store/
public ActionResult Details(int id)
var album = this.service.GetAlbum(id);
if (album == null)
return this.HttpNotFound();
return this.View(album);
public ActionResult Browse(string genre)
// Retrieve Genre and its Associated Albums from database
var genreModel = this.service.GetGenreByName(genre);
return this.View(genreModel);
public ActionResult Index()
var genres = this.service.GetGenres();
return this.View(genres);
// GET: /Store/GenreMenu
public ActionResult GenreMenu()
var genres = this.service.GetGenres();
return this.PartialView(genres);
StoreController from the begin solution now consumes StoreService. All the data references were removed
from StoreController, and now possible to modify the current data access provider without changing any method that consumes
StoreService.
You will find below that the StoreController implementation has a dependency with
StoreService inside the
class constructor.
Note: The dependency introduced in this exercise is related to Inversion of Control (IoC).
The StoreController class constructor receives an IStoreService type parameter, which is essential to
perform service calls from inside the class. However, StoreController does not implement the default constructor (with no
parameters) that any controller must have to work with ASP.NET MVC.
To resolve the dependency, the controller has to be created by an abstract factory (a class that returns any object of the specified
using System.Collections.G
using System.L
using System.W
using System.Web.M
using MvcMusicStore.ViewM
using MvcMusicStore.M
using MvcMusicStore.S
namespace MvcMusicStore.Controllers
public class StoreController : Controller
private IStoreS
public StoreController(IStoreService service)
this.service =
// GET: /Store/
public ActionResult Index()
// Create list of genres
var genres = this.service.GetGenreNames();
// Create your view model
var viewModel = new StoreIndexViewModel
Genres = genres.ToList(),
NumberOfGenres = genres.Count()
return View(viewModel);
// GET: /Store/Browse?genre=Disco
public ActionResult Browse(string genre)
var genreModel = this.service.GetGenreByName(genre);
var viewModel = new StoreBrowseViewModel()
Genre = genreModel,
Albums = genreModel.Albums.ToList()
return View(viewModel);
// GET: /Store/Details/5
public ActionResult Details(int id)
var album = this.service.GetAlbum(id);
return View(album);
Note: You will get an error when the class tries to create the StoreController without sending the service object, as there
is no parameterless constructor declared.
Task 1 - Running the Application
In this task, you will run the Begin application, which includes the service into the Store Controller that separates the data access from
the application logic.
When running the application, you will receive an exception, as the controller service is not passed as a parameter by default:
Open the Begin solution located in Source\Ex01-Injecting Controller\Begin.
You will need to download some missing NuGet packages before continue. To do this, click the Project menu and select
Manage NuGet Packages.
In the Manage NuGet Packages dialog, click Restore in order to download missing packages.
Finally, build the solution by clicking Build | Build Solution.
Note: One of the advantages of using NuGet is that you don't have to ship all the libraries in your project, reducing the
project size. With NuGet Power Tools, by specifying the package versions in the Packages.config file, you will be able to download all the
required libraries the first time you run the project. This is why you will have to run these steps after you open an existing solution from
Press Ctrl + F5 to run the application without debugging. You will get the error message &No parameterless
constructor defined for this object&:
Error while running ASP.NET MVC Begin Application
Close the browser.
In the following steps you will work on the Music Store Solution to inject the dependency this controller needs.
Task 2 - Including Unity into MvcMusicStore Solution
In this task, you will include Unity.Mvc3 NuGet Package to the solution.
Note: Unity.Mvc3 package was designed for ASP.NET MVC 3, but it is fully compatible with ASP.NET MVC 4.
Unity is a lightweight, extensible dependency injection container with optional support for instance and type interception. It is a
general-purpose container for use in any type of .NET application. It provides all the common features found in dependency injection mechanisms
including: object creation, abstraction of requirements by specifying dependencies at runtime and flexibility, by deferring the component
configuration to the container.
Install Unity.Mvc3 NuGet Package in the MvcMusicStore project. To do this, open the Package
Manager Console from View | Other Windows.
Run the following command.
PMCInstall-Package Unity.Mvc3
Installing Unity.Mvc3 NuGet Package
Once the Unity.Mvc3 package is installed, explore the files and folders it automatically adds in order to simplify
Unity configuration.
Unity.Mvc3 package installed
Task 3 - Registering Unity in Global.asax.cs Application_Start
In this task, you will update the Application_Start method located in Global.asax.cs to call the Unity
Bootstrapper initializer and then, update the Bootstrapper file registering the Service and Controller you will use for Dependency
Injection.
Now, you will hook up the Bootstrapper which is the file that initializes the Unity container and Dependency Resolver. To do this, open
Global.asax.cs and add the following highlighted code within the Application_Start method.
(Code Snippet - ASP.NET Dependency Injection Lab - Ex01 - Initialize Unity)
C#protected void
Application_Start()
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
Bootstrapper.Initialise();
AppConfig.Configure();
Open Bootstrapper.cs file.
Include the following namespaces: MvcMusicStore.Services and MusicStore.Controllers.
(Code Snippet - ASP.NET Dependency Injection Lab - Ex01 - Bootstrapper Adding Namespaces)
C#using System.Web.M
using Microsoft.Practices.U
using Unity.Mvc3;
using MvcMusicStore.S
using MvcMusicStore.C
Replace BuildUnityContainer method's content with the following code that registers Store Controller and Store
(Code Snippet - ASP.NET Dependency Injection Lab - Ex01 - Register Store Controller and Service)
C#private static
IUnityContainer BuildUnityContainer()
var container = new UnityContainer
container.RegisterType&IStoreService, StoreService&();
container.RegisterType&IController, StoreController&(&Store&);
Task 4 - Running the Application
In this task, you will run the application to verify that it can now be loaded after including Unity.
Press F5 to run the application, the application should now load without showing any error message.
Running Application with Dependency Injection
Browse to /Store. This will invoke StoreController, which is now created using
MVC Music Store
Close the browser.
In the following exercises you will learn how to extend the Dependency Injection scope to use it inside ASP.NET MVC Views and Action
Exercise 2: Injecting a View
In this exercise, you will learn how to use Dependency Injection in a view with the new features of ASP.NET MVC 4 for Unity integration. In
order to do that, you will call a custom service inside the Store Browse View, which will show a message and an image below.
Then, you will integrate the project with Unity and create a custom dependency resolver to inject the dependencies.
Task 1 - Creating a View that Consumes a Service
In this task, you will create a view that performs a service call to generate a new dependency. The service consists in a simple messaging
service included in this solution.
Open the Begin solution located in the Source\Ex02-Injecting View\Begin folder. Otherwise, you might
continue using the End solution obtained by completing the previous exercise.
If you opened the provided Begin solution, you will need to download some missing NuGet packages before continue. To do
this, click the Project menu and select Manage NuGet Packages.
In the Manage NuGet Packages dialog, click Restore in order to download missing packages.
Finally, build the solution by clicking Build | Build Solution.
Note: One of the advantages of using NuGet is that you don't have to ship all the libraries in your project, reducing the
project size. With NuGet Power Tools, by specifying the package versions in the Packages.config file, you will be able to download all the
required libraries the first time you run the project. This is why you will have to run these steps after you open an existing solution from
For more information, see this article: .
Include the MessageService.cs and the IMessageService.cs classes located in the Source
\Assets folder in /Services. To do this, right-click Services folder and select Add Existing
Item. Browse to the files' location and include them.
Adding Message Service and Service Interface
Note: The IMessageService interface defines two properties implemented by the
MessageService class. These properties -Message and ImageUrl- store the message and the URL
of the image to be displayed.
Create the folder /Pages in the project's root folder, and then add the existing class MyBasePage.cs
from Source\Assets. The base page you will inherit from has the following structure.
C#namespace MvcMusicStore.Pages
using System.Collections.G
using System.L
using System.W
using Microsoft.Practices.U
using MvcMusicStore.M
using MvcMusicStore.S
public class MyBasePage : System.Web.Mvc.WebViewPage&Genre&
[Dependency]
public IMessageService MessageService { get; set; }
public override void
Open Browse.cshtml view from /Views/Store folder, and make it inherit from
MyBasePage.cs.
C#@inherits MvcMusicStore.Pages.MyBasePage
ViewBag.Title = &Browse Albums&;
In the Browse view, add a call to MessageService to display an image and a message retrieved by the
HTML(C#)@inherits MvcMusicStore.Pages.MyBasePage
Viewbag.Title = &Browse Albums&;
@this.MessageService.Message
&img alt=&@this.MessageService.Message& src=&@this.MessageService.ImageUrl& /&
Task 2 - Including a Custom Dependency Resolver and a
Custom View Page Activator
In the previous task, you injected a new dependency inside a view to perform a service call inside it. Now, you will resolve that dependency
by implementing the ASP.NET MVC Dependency Injection interfaces IViewPageActivator and IDependencyResolver.
You will include in the solution an implementation of IDependencyResolver that will deal with the service retrieval by using
Unity. Then, you will include another custom implementation of IViewPageActivator interface that will solve the creation of
the views.
Note: Since ASP.NET MVC 3, the implementation for Dependency Injection had simplified the interfaces to register services.
IDependencyResolver and IViewPageActivator are part of ASP.NET MVC 3 features for Dependency Injection.
- IDependencyResolver interface replaces the previous IMvcServiceLocator. Implementers of IDependencyResolver must return
an instance of the service or a service collection.
public interface IDependencyResolver {
object GetService(Type serviceType);
IEnumerable&object& GetServices(Type serviceType);
- IViewPageActivator interface provides more fine-grained control over how view pages are instantiated via dependency
injection. The classes that implement IViewPageActivator interface can create view instances using context information.
public interface IViewPageActivator {
object Create(ControllerContext controllerContext, Type type);
Create the /Factories folder in the project's root folder.
Include CustomViewPageActivator.cs to your solution from /Sources/Assets/ to
Factories folder. To do that, right-click
the /Factories folder, select Add | Existing Item
and then select CustomViewPageActivator.cs. This class implements the IViewPageActivator interface to hold
the Unity Container.
C#namespace MvcMusicStore.Factories
using System.Collections.G
using System.L
using System.W
using System.Web.M
using Microsoft.Practices.U
public class CustomViewPageActivator : IViewPageActivator
private IUnityC
public CustomViewPageActivator(IUnityContainer container)
this.container =
public object Create(ControllerContext controllerContext, Type
return this.container.Resolve(type);
Note: CustomViewPageActivator is responsible for managing the creation of a view by using a Unity
container.
Include UnityDependencyResolver.cs file from /Sources/Assets to
/Factories folder.
To do that, right-click
the /Factories folder, select Add | Existing Item and then select
UnityDependencyResolver.cs file.
C#namespace MvcMusicStore.Factories
using System.Collections.G
using System.L
using System.W
using System.Web.M
using Microsoft.Practices.U
public class UnityDependencyResolver : IDependencyResolver
private IUnityC
private IDependencyR
public UnityDependencyResolver(IUnityContainer container, IDependencyResolver resolver)
this.container =
this.resolver =
public object GetService(Type serviceType)
return this.container.Resolve(serviceType);
return this.resolver.GetService(serviceType);
public IEnumerable&object& GetServices(Type serviceType)
return this.container.ResolveAll(serviceType);
return this.resolver.GetServices(serviceType);
Note: UnityDependencyResolver class is a custom DependencyResolver for Unity. When a service cannot be
found inside the Unity container, the base resolver is invocated.
In the following task both implementations will be registered to let the model know the location of the services and the views.
Task 3 - Registering for Dependency Injection within Unity
In this task, you will put all the previous things together to make Dependency Injection work.
Up to now your solution has the following elements:
A Browse View that inherits from MyBaseClass and consumes MessageService.
An intermediate class -MyBaseClass- that has dependency injection declared for the service interface.
A service - MessageService - and its interface IMessageService.
A custom dependency resolver for Unity - UnityDependencyResolver - that deals with service retrieval.
A View Page activator - **CustomViewPageActivator ** that creates the page.
To inject Browse View, you will now register the custom dependency resolver in the Unity container.
Open Bootstrapper.cs file.
Register an instance of MessageService into the Unity container to initialize the service:
(Code Snippet - ASP.NET Dependency Injection Lab - Ex02 - Register Message Service)
C#private static
IUnityContainer BuildUnityContainer()
var container = new UnityContainer();
container.RegisterType&IStoreService, StoreService&();
container.RegisterType&IController, StoreController&(&Store&);
container.RegisterInstance&IMessageService&(new
MessageService
Message = &You are welcome to our Web Camps Training Kit!
ImageUrl = &/Content/Images/webcamps.png&
Add a reference to MvcMusicStore.Factories namespace.
(Code Snippet - ASP.NET Dependency Injection Lab - Ex02 - Factories Namespace)
C#using System.Web.M
using Microsoft.Practices.U
using Unity.Mvc3;
using MvcMusicStore.S
using MvcMusicStore.C
using MvcMusicStore.F
Register CustomViewPageActivator as a View Page activator into the Unity container:
(Code Snippet - ASP.NET Dependency Injection Lab - Ex02 - Register CustomViewPageActivator)
C#private static
IUnityContainer BuildUnityContainer()
var container = new UnityContainer();
container.RegisterType&IStoreService, StoreService&();
container.RegisterType&IController, StoreController&(&Store&);
container.RegisterInstance&IMessageService&(new MessageService
Message = &You are welcome to our Web Camps Training Kit!&,
ImageUrl = &/Content/Images/webcamps.png&
container.RegisterType&IViewPageActivator, CustomViewPageActivator&(new InjectionConstructor(container));
Replace ASP.NET MVC 4 default dependency resolver with an instance of UnityDependencyResolver. To do this, replace
Initialise method content with the following code:
(Code Snippet - ASP.NET Dependency Injection Lab - Ex02 - Update Dependency Resolver)
C#public static
void Initialise()
var container = BuildUnityContainer();
DependencyResolver.SetResolver(new Unity.Mvc3.UnityDependencyResolver
(container));
IDependencyResolver resolver = DependencyResolver.C
IDependencyResolver newResolver = new Factories.UnityDependencyResolver
(container, resolver);
DependencyResolver.SetResolver(newResolver);
Note: ASP.NET MVC provides a default dependency resolver class. To work with custom dependency resolvers as the one we have
created for unity, this resolver has to be replaced.
Task 4 - Running the Application
In this task, you will run the application to verify that the Store Browser consumes the service and shows the image and the message
retrieved:
Press F5 to run the application.
Click Rock within the Genres Menu and see how the MessageService was injected to the view and loaded
the welcome message and the image. In this example, we are entering to &Rock&:
MVC Music Store - View Injection
Close the browser.
Exercise 3: Injecting Action Filters
In the previous Hands-On lab Custom Action Filters you have worked with filters customization and injection. In this
exercise, you will learn how to inject filters with Dependency Injection by using the Unity container. To do that, you will add to the Music
Store solution a custom action filter that will trace the activity of the site.
Task 1 - Including the Tracking Filter in the Solution
In this task, you will include in the Music Store a custom action filter to trace events. As custom action filter concepts are already
treated in the previous Lab &Custom Action Filters&, you will just include the filter class from the Assets folder of this lab, and
then create a Filter Provider for Unity:
Open the Begin solution located in the Source\Ex03 - Injecting Action Filter\Begin folder. Otherwise,
you might continue using the End solution obtained by completing the previous exercise.
If you opened the provided Begin solution, you will need to download some missing NuGet packages before continue. To do
this, click the Project menu and select Manage NuGet Packages.
In the Manage NuGet Packages dialog, click Restore in order to download missing packages.
Finally, build the solution by clicking Build | Build Solution.
Note: One of the advantages of using NuGet is that you don't have to ship all the libraries in your project, reducing the
project size. With NuGet Power Tools, by specifying the package versions in the Packages.config file, you will be able to download all the
required libraries the first time you run the project. This is why you will have to run these steps after you open an existing solution from

Add a IUnityContainer property in the FilterProvider class, and then create a class constructor to
assign the container.
(Code Snippet - ASP.NET Dependency Injection Lab - Ex03 - Filter Provider Constructor)
C#public class
FilterProvider : IFilterProvider
private IUnityC
public FilterProvider(IUnityContainer container)
this.container =
Note: The filter provider class constructor is not creating a new object inside. The container is passed
as a parameter, and the dependency is solved by Unity.
In the FilterProvider class, implement the method GetFilters from IFilterProvider
interface.
(Code Snippet - ASP.NET Dependency Injection Lab - Ex03 - Filter Provider GetFilters)
C#public class
FilterProvider : IFilterProvider
private IUnityC
public FilterProvider(IUnityContainer container)
this.container =
public IEnumerable&Filter& GetFilters(ControllerContext
controllerContext, ActionDescriptor actionDescriptor)
foreach (IActionFilter actionFilter in this.container.ResolveAll&IActionFilter&())
yield return new Filter
(actionFilter, FilterScope.First, null);
Task 2 - Registering and Enabling the Filter
In this task, you will enable site tracking. To do that, you will register the filter in Bootstrapper.cs
BuildUnityContainer method to start tracing:
Open Web.config located in the project root and enable trace tracking at System.Web group.
&system.web&
&trace enabled=&true&/&
&compilation debug=&true& targetFramework=&4.5&&
Open Bootstrapper.cs at project root.
Add a reference to the Filters namespace.

C#using System.Web.M
using Microsoft.Practices.U
using Unity.Mvc3;
using MvcMusicStore.S
using MvcMusicStore.C
using MvcMusicStore.F
using MvcMusicStore.F
Select the BuildUnityContainer method and register the filter in the Unity Container. You will have to register the
filter provider as well as the action filter.

website for each enabled publication method. The publish profile contains the URLs, user credentials and database strings required to connect
to and authenticate against each of the endpoints for which a publication method is enabled. Microsoft WebMatrix 2,
Microsoft Visual Studio Express for Web and Microsoft Visual Studio 2012 support reading publish profiles to
automate configuration of these programs for publishing web applications to Windows Azure websites.
Downloading the Web Site publish profile
Download the publish profile file to a known location. Further in this exercise you will see how to use this file to publish a web
application to a Windows Azure Web Sites from Visual Studio.

Task 2 - Configuring the Database Server
If your application makes use of SQL Server databases you will need to create a SQL Database server. If you want to deploy a simple
application that does not use SQL Server you might skip this task.
You will need a SQL Database server for storing the application database. You can view the SQL Database servers from your subscription
in the Windows Azure Management portal at Sql Databases | Servers | Server's Dashboard. If
you do not have a server created, you can create one using the Add button on the command bar. Take note of the server
name and URL, administrator login name and password, as you will use them in the next tasks. Do not create the database yet, as it
will be created in a later stage.
SQL Database Server Dashboard
In the next task you will test the database connection from Visual Studio, for that reason you need to include your local IP address in
the server's list of Allowed IP Addresses. To do that, click Configure, select the IP address from
