So I want to use the XboxLive features with unity. The only way I found is using this plugin : https://github.com/Microsoft/xbox-live-unity-plugin (look like an official one). If I start an empty project : no problem during build (for windows 10 universal app, XAML, .NET, using unity 5.6.1f1 with windows SDK and visual studio tools for UWP installed). If I add the plugin I try to build I got this : Looks like the dll used in this plugin use something that is not in the .NET framework. That's really ironic that the only plugin that does not work in .Net is the official XboxLive services one. Does anyone succeded to use XboxLive plugin and build?
