- If they are separate, will they run on a server or a peer within the local area network, an intranet or specific subdomain, or the Internet?
- How do you transmit data? Secure Sockets? Plaintext? A syndication component? Do you have an authorization or authentication model separate from the Windows Identity model?
- How do you plan to deploy your application? In the Windows Store, or via side-loading?
- Can some functionality be moved to the client, now that you have access to a broader spectrum of client features and behaviors?
The Windows Runtime provides several namespaces and classes for communication, streaming, security, client package deployment, data sharing, and syndication. The following table lists these namespaces and their contents:
|Windows.ApplicationModel.Search||Defines the classes for implementing the Windows search pane in an app. The search pane is a touch-friendly search box that offers type-ahead suggestions to the user. Using the search pane in your application gives the user a way to enter search queries that is consistent with other apps.|
|Windows.Data.Html||Defines a set of utility classes for working with HTML.|
|Windows.Management.Deployment||Defines types that provide functionality for managing Windows Store app packages in Windows 8. Functionality includes API elements to add, update, remove, stage, register, and enumerate packages.|
|Windows.Media||Defines classes for creating and working with media such as photos, audio recordings and videos.|
|Windows.Media.PlayTo||Defines classes and interfaces for streaming audio, video, and images to remote devices.|
|Windows.Networking.BackgroundTransfer||Defines classes for advanced download and upload transfer capabilities within an app.|
|Windows.Networking.Connectivity||Defines types used in a cost-aware application. Specifically, it defines the types that can tell the application exactly how much certain activities (such as a large download on a metered connection) will cost in terms of usage data.|
|Windows.Networking.NetworkOperators||Defines classes that support mobile broadband account management.|
|Windows.Networking.PushNotifications||Defines classes and interfaces that encapsulate push notifications for network events.|
|Windows.Networking.Sockets||Defines classes that are used to define networking sockets (such as datagram, stream, and web) for both local subnet and Internet-aware connections.|
|Windows.Security.Authentication.OnlineId||Defines classes that enable Windows Store apps to use Windows Live to authenticate users using their Microsoft account. After authentication, apps can get back a JSON token with an ID that can be used for that user with your app.|
|Windows.Security.Authentication.Web||Defines classes that enable Windows Store apps to integrate with online web services, such as Facebook, without exposing a user's credentials. This is accomplished by using protocols like OAuth and OpenID.|
|Windows.Security.Credentials||Defines classes for securely storing and managing user passcodes, passphrases, and other identification information.|
|Windows.Security.Cryptography.Certificates||Defines classes that you can use to create certificate requests and install certificate responses.|
|Windows.Security.Cryptography.DataProtection||Defines classes that enables you to easily encrypt and decrypt static data or a data stream.|
|Windows.Web.AtomPub||Defines the classes, delegates, and interfaces needed to implement the AtomPub protocol. This protocol enables HTTP CRUD access to Web resources by using the Atom 1.0 wire format.|
|Windows.Web.Syndication||Defines the types that provide functionality for managing syndication feeds.|
