Disclaimer; I don’t know the actual cost of developing and maintaining Visual Studio, but I wouldn’t be surprised if a billion dollars is its total cost, over the 30+ years it has existed, considering its strategic importance to Microsoft, and its feature set.
Motivation; My motivation for writing this article, was the comments at Reddit.com about another guy who did something similar. So this article is arguably a comment to that thread.
Anyways, I arguably created Visual Studio in 7 days, and I created it in such a way, that it works on Linux, Mac, Windows, iPhones, Androids, iPads, Tablets in general, and probably your grandma’s fridge, if it has a browser. In fact, if I truly wanted to, I’d probably have it working on Lynx if I wanted to. The only reason why I could do that, is because I do not suffer from neither the “not invented here syndrome”, nor do I suffer from the “we need an app syndrome”. If you don’t believe me, I encourage you to watch this video, for then to download the code, and check it out for yourself. So basically …
I created a billion dollar “app” in 7 days!
