You are developing a Windows Store app that will provide users with the ability to subscribe to
content by using in-app purchases.
You need to test the in-app purchase functionality of the app before you deploy the app to the
Windows Store.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

A.
Modify the Windowsstoreproxy.xml file.

B.
Modify the App.xaml file.

C.
use the CurrentAppSimulator class.

D.
use the CurrentApp class.

E.
Modify the Package.appxmanifest file.

Explanation:

When you code and test new in-app offers for the first time, you must use the CurrentAppSimulator
object instead of the CurrentApp object. This way you can verify your license logic using simulated
calls to the license server instead of calling the live server. To do this, you need to customize the file
named “WindowsStoreProxy.xml” in <installation_folder>\Microsoft\Windows Store\ApiData. The
Microsoft Visual Studio simulator creates this file when you run your app for the first time—or you
can also load a custom one at runtime. For more info, see CurrentAppSimulator docs.
