Question

What controls CurrencyPositivePattern in .NET.

At startup

var x = 10.0M;

Console.WriteLine(typeof(Program).Assembly.ImageRuntimeVersion);

var culture = System.Globalization.CultureInfo.GetCultureInfo("da-DK");

Console.WriteLine(culture.NumberFormat.CurrencyPositivePattern);
Console.WriteLine(x.ToString("C", culture));

We see the difference when using different versions of the frame.
