Google data is good API tool for C# or other language to connect with Google related service, however here is no official Google Reader API on document. and Google data don’t support for Windows phone (only for Windows mobile for now). However it could be found on web for some of unofficial document for Google Reader API as follows: Unofficial Google Reader API R2 google reader on Google code pyfeed on Google code But however to come out detail implement for Windows Phone, it quit need time to work detail. Allow me try to list some major problems of this. Most important of using HttpWebRequest is the error repose > > The remote server returned an error: NotFound > > It is most common error code your will find during you try to login or get any feedback on Window Phone.

According to Metro Application Lifetime sample and related document, it description about Metro app about suspend/resume.
However, I also find I could not make my Metro app enter suspend mode, so I try to figure out some answer from MSFT forum. Refer here and here.
Here is my summary for this:
When leave app about 5 sec or trigger another app about 5 sec, the “suspend” event will called.
“Suspends”/”Resume” event will trigger automatically when you not attach debugger on release build. See “Star without Debugging” on “debug” tab.
If you using debugger, you only trigger “suspend” manually.
Sleep/Hibernate will trigger “Suspend” if your app is release version without debugger attach.
From last article “HOW TO COMMUNICATE BETWEEN METRO UI AND DESKTOP UI ON WIN8”, it talking about to pass the control between Metro/Desktop application. However during programing on Metro and Desktop, you might need some communication mechanism for Metro/Desktop application. I just provide my experience for this kind of question, here is my solution for communicate between Metro and Desktop on Win8 Customer Preview. (I also feedback on MSFT forum here) Write a application to listen TCP as information center which call “DesktopSvr” (ex: here) Metro app try to send message to localhost via streamsocket (P.S. localhost is not work, but 127.0.0.1 work well). “DesktopSvr” will pass desktop app via IPC or anyway you familiar. Metro application communication guidline: Desktop might also pass some data to “DesktopSvr” it will be our information center. Metro: Since Metro UI will not get any TCP feedback if app under suspends, so communicate between...
