So merging @Jon Skeet answer with this one
The Real Answer was to add this method to the Global.asax.cs file of your MVC Project. And that's it.
The key is the second line:
protected void Application_BeginRequest(object sender, EventArgs e)
{
CultureInfo culture = new CultureInfo("en-us");
culture.NumberFormat.CurrencyNegativePattern = 1;
Thread.CurrentThread.CurrentUICulture = culture;
Thread.CurrentThread.CurrentCulture = culture;
}
