Unable to reference Box api from Windows Phone 8.1 project

Hi,

I am working on a Windows Phone 8.1 project and would like to use some Box api features. I am using Visual Studio 2015 with the Windows Phone SDK installed.

I am unable to install the Box sdk through nuget (even the earlier versions). The nuget package manager does state the Box.V2 sdk earlier versions are supported on Windows Phone 7.5 or higher but I am not sure why I am not able to install the package for my project. I see an error about one of the dependencies Nito.AsyncEx which does not target WindowsPhoneApp, Version=v8.1.

Has anyone successfully used the Box Api with a Windows Phone 8.1 project? Any help would be appreciated.

Thanks!
