Windowsphone8.1rt creating a blank app cannot save data

wp8.1, the problem encountered after building a blank application: you want to achieve save, extract data can not be successful

1, the program will first run MainPage (), and then into the Onnavigatedto (), before the first run onnavigatedto.

2: Unable to enter the Onnavigatedfrom () after exiting the program.

Online say to manually invoke the Onsuspending event?

-------------------Shabby dividing line-----------------------------

Later learned that in the blank application of the lack of SuspensionManager.cs, NavigationHelper.cs, etc.

Although said can add their own, but the trouble, need to fly a lot of kung Fu.

So the advice is: build other non-empty projects and build your own mainpage with BasePage.

In addition, you may have problems when you want to save data while running on the emulator.

Report:

On Windows Phone, Onnavigatedfrom () was called when the app was suspended.

Onnavigatedto () isn't called when the app is resumed.
