Silver generates pure Java .jar files and Android .apk files containing such, so any post-processing tools available for the platform can be applied to Silver, and should work in the exact same way as they do for apps created with the Java language.
VS2015 is supported in the current release, if you have Pro or (free) Community Edition installed. A future update will include/install the VS2015 Shell for you, as soon as Microsoft makes that available (they have not yet).
