I am using visual studio 2019. When I use doubles, it uses "," instead ".". I get error if I use ".". I searched around and I can change it but I want to change it inside setting so that it automatically uses "." and not ",".
this is code i use.
double d = double.Parse(Console.ReadLine());
Console.WriteLine(d);
and if i type 4.6 (decimal with .) it gets this error.
Unhandled exception. System.FormatException: Input string was not in a correct format.
at System.Number.ThrowOverflowOrFormatException(ParsingStatus status, TypeCode type)
at System.Double.Parse(String s)
at project3.Program.Main(String[] args) in C:\Users\a2bme\source\repos\project3\Program.cs:line 9
but 4,6 works fine. I have worked with some other languages and am used to ".".
edit:
I know about CultureInfo.InvariantCulture
and want a way without using it every time.

If "," is valid and "." is not valid A simple solution can be this. Now you can enter 4.5 or 4,5 and both will work.
using System;
public class Program
{
public static void Main()
{
var input = Console.ReadLine().Replace(".", ",");
double d = double.Parse(input);
Console.WriteLine(d);
}
}

If you only need to format the decimal number use
String.Format("{0:n}", numb)
