IAP for Unity Windows Phone 8.1

I bought the Plugin from Reign-Studios. There are examples in the DemoScenes directory. The environment is Visual Studio 2015 Community for a Windows Phone 8.1 project.

Things to be noticed:

• In Unity
• Edit->Reign->Check for updates to check version
• Edit->Reign->Download UnityPackage Updates to get the latest version

• In VS, read the following links first
1. http://reign-studios.net/docs/windows-8/
2. http://reign-studios.net/docs/windows-8/ads/

The step 6 for document 2 is not available for VS2015 Community. The following steps are working for me

For AdDuplex

• Right click on the Reference in Solution Explorer and choose Manage NuGet Packages
• Search "AdDuplex"
• Install AdDuplexWin81 and AdDuplexWinPhone81

For Microsoft Advertising SDK(credits to stackoverflow)

• Download and Install from here 
• Right click on Reference in Solution Explorer and choose Add Reference
• Select Windows Phone 8.1 -> Extensions and Select Microsoft Advertising SDK for Windows Phone 8.1 (XAML)
