This post links to a different page. It shows three big boxes: One for iOS, watchOS, tvOS and MacOS X. One for Android. And a third one which provides a forms package providing native UI on iOS, Android and Windows. Which just received huge updates AND went open source.<p>There is a language: C#. There are bindings to native toolkits. There&#x27;s yet another imperfect Forms package. And there&#x27;s a slightly wonky IDE. I&#x27;m not sure what you&#x27;re expecting but I think the &quot;lossy abstraction&quot; here is mostly your expectations. I also think you are applying your narrow experience (which obviously was not a great one) and trying to amplify it by using unsubstantiated statements like &quot;most teams&quot; and &quot;few wins.&quot;
