Does anyone know of an already implemented money type for the .NET framework that supports i18n (currencies, formatting, etc)? I have been looking for a well implemented type and can't seem to find one.

The best datatype to use for currency in C# is decimal. The decimal type is a 128-bit data type suitable for financial and monetary calculations. The decimal type can represent values ranging from 1.0 * 10^-28 to approximately 7.9 * 10^28 with 28-29 significant digits.
The "C" (or currency) format specifier is used to convert a number to a string representing a currency amount. Let us see an example. double value = 139.87; Now to display the above number until three decimal places, use (“C3”) currency format specifier.
The decimal keyword indicates a 128-bit data type. Compared to floating-point types, the decimal type has more precision and a smaller range, which makes it appropriate for financial and monetary calculations.

I think you want to use the decimal data type, and use the appropriate overload for ToString().
CultureInfo current = CultureInfo.CurrentCulture;
decimal myMoney = 99.99m;
//formats as money in current culture, like $99.99
string formattedMoney = myMoney.ToString("C", current);
