Different outputs when running coverlet.console on windows powershell/macOS terminal

I’m running coverlet.console on macOS and no coverage is generated for my project which actually does cover the dll it aims to test.

I tried to see if I got the same on windows powershell, but surprisingly, it does show coverage there for the exact same file and command

The content of the test and the application proj itself it’s super simple:

test:

public class HeartbeatIntervalProviderTests
    {
        [Fact]
        public void Provide01()
        {
            var options = Options.Create(new HeartbeatIntervalConfig
            {
                IntervalInSeconds = 10
            });

            var provider = new HeartbeatIntervalProvider(options);

            Assert.Equal(10, provider.Provide());
        }
    }

project has 2 classes:

public class HeartbeatIntervalProvider : IHeartbeatIntervalProvider
    {
        private readonly HeartbeatIntervalConfig _config;

        public HeartbeatIntervalProvider(IOptions<HeartbeatIntervalConfig> config)
        {
            _config = config.Value;
        }

        public int Provide()
        {
            return _config.IntervalInSeconds;
        }
    }

public class HeartbeatIntervalConfig
    {
        [Range(1, 1000000)]
        public int IntervalInSeconds { get; set; }
    }

Still a problem for us who use the console version of the tool, right?

I have the same problems.
