We are happy to announce the immediate availability of AdDuplex SDK for Windows 8.1 XAML apps (including both C#/VB.NET and C++ based apps).
Install the SDK via the Visual Studio extension by searching for AdDuplex in the Visual Studio Gallery directly from within Visual Studio (Tools > Extensions and Updates > Online > Visual Studio Gallery), select “AdDuplex SDK for Windows 8.1 (XAML)”. Or just get it from the Gallery web page. See the Documentation for details.
Note: due to an incompatibility of Nuget with the new way XAML controls are distributed for Windows 8.1 we recommend you use Visual Studio extension to get the SDK. We will make the Nuget version available at a later date once the issue is resolved.
