CultureInfo.CurrentCulture = CultureInfo.InvariantCulture; Is it possible to solve this?

Should I use CultureInfo.InvariantCulture for all Convert.To functions?

Resolution Note:
Convert.ToSingle is culture specific function, you can reproduce the same issue in simple .NET application
CultureInfo.CurrentCulture = new CultureInfo("ru-RU");
Convert.ToSingle("0.13")
The proper fix, would be to do
Convert.ToSingle("0.13", CultureInfo.InvariantCulture) is it would language independent.
