WINDOWS8 development-about WP7 app migration to WIN8 Metro style

Although Microsoft said that WP7 application porting to Win8 above is relatively simple, only need to modify some of the API and design in principle the details, but also provides a relatively concise reference document;

In fact, this kind of migration is still a lot of work, especially when the application refers to more underlying APIs.

Here are a few issues to consider in porting your application:

(1) UI: Basically all of the UI page will be changed, mainly a reference library changes, some wp7 on the win8 above the control is not supported, such as PhoneApplicationPage.

(2) Database: Currently WIN8 no source database, but can use SQLite to achieve data storage; Win8 also does not support sqlce databases in WP7.

(There are still system.data.linq such Win32 libraries in WIN8, which can only be faulted if the 64-bit environment compiles)

(3) If the original WP7 application also involves registering a mobile phone alarm clock, but also have to reconsider the logic of the bell. There is no concept of a clock in win8, but consider switching to a supported message push notification (i.e. implementing timed push notifications, referring to blogs).

(4) Background process model: WIN8 background model and WP7 similar, background process cannot run continuously (interval run once), can refer to: Blog or MSDN document.

(5) Other changes to the reference library. For the time being, we have not found a complete reference document, only scattered search and replace.

We have to spit out a bit. NET libraries, a DLL library will have n multiple versions, accidentally will be wrong ... It's a catastrophe to use such a library.
