Tracks On Tracks On Tracks test 9 error

Exercism

Hi Everyone,
I keep getting this error for task 9 in the exercise Tracks On Tracks On Tracks:

We received the following error when we ran your code:
TracksOnTracksOnTracks.cs(28,91): error CS0029: Cannot implicitly convert type 'bool' to 'System.Collections.Generic.List<string>'

Here is my solution:

 public static bool IsUnique(List<string> languages)
    {
        HashSet<string> set = new HashSet<string>();
        foreach (string item in languages)
        {
            if (!set.Add(item))
                return false;
        }
        return true;
    }

I’m guessing the error is a faulty test implementation. I have also tried the LINQ solution below that generates the same error:

    public static bool IsUnique(List<string> languages) => languages.Count == languages.Distinct().Count();
2

Which one is line 28?

Haha, I looked at the wrong line… It works as intended - Sorry for confusion.
