What does Unity have to do with Xamarin? Are you referring to the fact that Unity uses an old version of Mono, because that hardly is relevant to greenspot&#x27;s comment.<p>To their actual comment, it is extraordinarily difficult to make a quality product with Xamarin. As they said, there are <i>shockingly</i> few wins built with it. There are loads and loads of teams using it, all sure that it&#x27;s the short cut that will build for everything with one code base, but so few wins.
