Description Dimitar Dobrev 2016-04-07 02:12:20 UTC
This sample:

public class Program
        public void Arg(double a, int fieldWidth = 0, char fmt = 'g', int prec = -1)

        public void Arg(char a, int fieldWidth, QChar fillChar)

        public void Arg(char a, int fieldWidth = 0)
            Arg(a, fieldWidth, ' ');

        public partial class QChar
            public static implicit operator QChar(char ch)
                return new QChar();

compiles with .NET but with Mono it gives the following error:

(11,13): error CS0121
: The call is ambiguous between the following methods or properties: 'Arg(double, int, char, int)' and 'Arg(char, int, QChar)'
