Update S1905: False Positive with 'default'

[nnpcYvIVl]

Description

This code throws S1905 but when I make the recommended change the code fails to compile with CS0411. Is this a false positive?

using System;

namespace S1905_False_Positive
{
    internal static class Class
    {
        public static void RunAction(Action action)
        {
            RunFunc(() => { action(); return default; }, (bool)default);
        }

        public static T RunFunc<T>(Func<T> func, T returnvalue = default)
        {
            try
            {
                return func();
            }
            catch (Exception)
            {
                return returnvalue;
            }
        }
    }
}

Hi @nnpcYvIVl,

This is indeed a FP! This is due to the unsupported (on our side) syntax default.
