Create calculation independence (from Windows system) for visual basic programs with netcore 8

### Description

Hi, I'm a visual basic (.net) programmer. Now I create the programs with netcore. 8.
This is not a bug but a kind of request (if it can be done with future netcore 8 stable version).
I have created various programs to make economic calculations, I have noticed, it has been like this for years now, that calculations with the comma must be done with the point. That is, if you want to do 2,5 + 10,9 (for example), you have to write 2.5 + 10.9. No sense but ok.
Now I wanted to ask, is't possible to create something independent of windows? In the sense that, the visual basic programs written with netcore 8 or 7 or 6 etc. are dependent on the Windows system in many things and it would be good to make them even more performing and also independent (ie detaching from the dependencies of the windows system). One of them is the calculator, because the calculations are definitely done using the Windows system. Netcore always comes out with a new release and new changelogs, however the "dependencies" issue (as regards visual basic .net) is minimal and frankly no, I'm not going back to the 4.8 framework (it's less performing than netcore6 or 7 or 8).
Among so many things for visual basic, in the new netcore 8 stable version, it would be nice to see more performance and above all more "nativity" and less dependencies on Windows (dll, exe, etc), also as regards computers, maybe keeping the point, what you want. Of course having independence from the main system would be a very good thing for programs written in visual basic (which have remained the same and behind). In this case of course this "request" was only for the calculator, (I don't mean a calculator but having in the netcore 8 installation package everything you need to do the calculations without the program interfacing with the Windows version of that moment).
Thank you

### Configuration

Netcore 8

Windows 7, Widows 8.1, Windows 10

### Other information
Naturally mine is not a purely philosophical discourse because it's cool to detach from Windows dependencies, the discourse is more than anything else
1) Be logical because it's time that netcore 8 also look a little at the performance of programs that are used to make calculations, but no asp or others, I'm also talking about Visual basic which has been put on the back burner.
2) Also logical because a netcore installation file that weighs a total of MB, i.e. weighs a lot but doesn't create too many independencies (so O_o)?
So why not put more "things" that make Windows detach (like for example detaching from the work done by Windows to do the calculations, be it the addition (+) the subtraction - the square root, multiplication, percentage calculation or whatever else).

Thank you
