From the Microsoft Store to see the development of the technology used

Ash pulls out a long time to eat Lumia 950
than that, the FIG.

This is the Microsoft Store application on Windows Phone
a developing the App, except than Controls, also using some Mechanism, for example to communication between applications, file access, user authentication, acquires sensor data, etc.
Today, I'll be there on the shining Microsoft Store this application to say something about my views.

App-to-app

This is Microsoft Store inside the application interface to share, click on the application you are currently viewing will be sent a link way to another application, this application can be sent to others (such as QQ)
This is Dev-Center:App-to-app
specific implementation, probably (my guess) when the share button will trigger a DataRequested event, and to share the data into DataPackage, and then sent to the target App

This function is basically all applications will use, very used, but the form will be relatively simple.
Although Microsoft provided DataPackage class scalability, but for most applications it is just a text sharing.

Data access

data access, which is almost the basic functions of the data is the basis for an App, and Microsoft Store as an application center, while access to their own data, but also to be responsible for the installation of other applications. Data access is high.
Microsoft Store to store information about all the local version of the application, installation status, it must have a database locally (probably using a SQLite), but also be able to query and its application, display information , which in turn necessitates a remote database (SQL Server), so this part of the Data access is necessary.
Dev-Center is put this part of the database access (database connection), the local user and the remote database using SQLite using SQL Server. In view of the SQL Server is pro-son, Microsoft Store is basically the distal certainly use the SQL Server.
Dev-Center：SQL Server

Launching, resuming, and background tasks

This is no running in the background of the diagram :(

A short application store, be sure to support the application can be downloaded in the background and install updates, otherwise no one would be willing to open application store to wait long to update those people crash
Dev-Center：Support your app with background tasks

Moreover, we often find that many applications, such as "Love application", click to download the application will jump to download Microsoft Store, which uses here Launching, use a URI to evoke an application.
Dev-Center：Launch an app with a UR

Networking and web services

network, and web services, application store if it is not the lack of these two applications the shops.
download the application, the application needs to update the network, to transfer large blocks of data, for stability, error rate
find application, a browser application also requires network to transmit small application information data, requiring high speed
In order to meet the needs of the background download and update is required Background Transfer
Microsoft herein provides different network protocols to choose: Socket, WebSocket, HTTP, etc.
Dev-Center：Networking and web services

Security

application store Microsoft account to sign in! Microsoft account! Account!
This is a lot of white or novice prohibitive place - too much trouble
, however, have to say this is a responsible approach.
digress. . .

App Store is based on the Microsoft account, naturally, user login, verification is essential to the function.
Microsoft provides a very intimate AccountsSettingsPane class to deal with problems associated with the account and the like.
to see the details Dev-Center to:Web Account Manager

PC is dead, hastily written here.
is somewhat surprised that he was the one with the most class :)
