A Visual Studio and MonoDevelop version of the sample program.

When using Double.TryParse to convert German text to a double, "+unendlich" does not get converted to Double.Infinity.  Double.TryParse does convert "+unendlich" in Visual Studio using the same code.

Sample program:

using System;
using System.Globalization;

namespace TryParse
    class MainClass
        public static void Main(string[] args)
            double value;
            IFormatProvider german = new CultureInfo("de-DE");
            bool succeeded = Double.TryParse("+unendlich", NumberStyles.Float, german, out value);
            if (succeeded)
                Console.WriteLine("The converted text = " + value);
                Console.WriteLine("TryParse returned null");
