Trial apps in Windows Phone 8

Question

In WinPhone 8 SDK, there are two LicenseInformation classes:

• Microsoft.Phone.Marketplace.LicenseInformation (present since WP7.0)
• Windows.ApplicationModel.Store.LicenseInformation (WinRT-inspired)

And two ways to initiate a full product purchase:

• via MarketplaceDetailTask with app GUID as ContentIdentifier
• via CurrentApp.RequestAppPurchaseAsync

They're slightly different. Which one should I use?

You should use MarketplaceDetailTask with the Microsoft.Phone.Marketplace.LicenseInformation class.
