Convert.ToDouble(“4089.90”) outputs 40.899,00 why?

Question

I am developing a software that uses number precision, but I have this problem, it happens that when I take a string to convert to double it outputs me with a different culture.

Answer 1

Culture could be based on where the ASP.Net application is running, and not the client PC that is running the browser. While their desktop PC might have similar culture settings, the server may differ.
