C# is non portable. That is it. It is that simple. [/] I’m sure the Mono and Xamarin people are devastated to learn that what they’re doing is impossible. ---

Answer to the Op and based in this unity page [http://blogs.unity3d.com/2014/05/20/the-future-of-scripting-in-unity/http://](http://blogs.unity3d.com/2014/05/20/the-future-of-scripting-in-unity/http://) C# runtime performance still lags behind C/C++ Garbage collection can cause pauses while running C++ compilers and linkers provide a vast array of advanced optimisations previously unavailable. Fundamentally, it differs from the current implementation in that the IL2CPP compiler converts assemblies into C++ source code. It then leverages the standard platform C++ compilers to produce native binaries. ---

I like blueprints 🆒 Btw you can think that programming in general sucks but you have to prove the vicious engine script, this a another level, regarless to my love to vicious engine multiplatafom support. ---

[=gmpreussner;136998] And by the way, programming in general [sucks](http://stilldrinking.org/programming-sucks) 😉 [/] Oh what a roller coaster this thread has been. Starting from mild curiosity, to entertainment, then dismay, pleading, turning into a deep self introspective journey into the ability of the human race to find common ground and find peace, the possibility of life on Mars, then back to entertainment and mild curiosity. That link there was about the best thing I’ve read in weeks. And let me tell you, I just read a SciFi book that was highly rated by over 2,000 amazon reviews which I believe I could have achieved better during my morning constitutionals by doodling on excess toilet paper, collecting the scraps, and shipping the collection to Random House Publishing. So, I needed that short masterpiece in writing in multiple ways. ---

[=;136878] You really don’t understand the point. The point being not to which platform you can deploy your game but on which platform you can run your engine. [/] What? If you can deploy a game to a given platform then the engine must run on that platform - or you can’t deploy your game to that platform. “Deploy” is not just “copy the files over and stare at them,” it is “install and run on a given platform.” ---

You either use superior rhetoric, or superior facts; and over the entire course of your engagement here, you have failed at providing or utilizing either. All you’re doing is repeating “I am right, you are wrong” over and over again. This only serves to prove one point: That you have a lot of opinion and nothing to actually back it up. Hell, there’s an entire company and thousands of developers out there who are very successful and whose main product is predicated on you not being as right as you think you are.
