Earlier quoted context omitted.
It isn't a proprietary language. Anyone can implement the language spec. Do you people do any basic research, you know just googling or reading the license?
> Anyone can implement the language spec. No. So far, only Microsoft has implemented the language spec and as long as no one else does it, no one can. Prove to me that "anyone can implement it" by pointing to someone who has done it, instead of relying on some theoretical "it could be done" fantasy. The amount of effort, time, energy needed is just not something anybody else outside of MS is able or willing to put in…
Yes I am sure that it takes a lot of time, but anyone who is willing and able can do it there is no-one stopping anyone from doing it.
The spec is open, the source code for pretty much everything is now open and is sitting on github, it has been ported to MacOS, iOS and Linux and it runs on both x86 and ARM what more do you people want?
