C# Intermediate C# Polymorphism Virtual Properties

Bug in the "Virtual Properties" task in Intermediate C# course.

There is a bug in this objective, the "Preview" button is nowhere to be seen thus making it impossible to check the console error. Because of that I have no idea what I'm doing wrong in my code.

I'm having the same issue, haven't gotten past the first step even though I'm sure my code is right: 

public override string Description => "Detects repetitions";

did you get past the first step?

No I didn't get past the first step, looks like it's impossible. I have tried doing it in every possible way: same as you did (which I'm sure is correct), as an auto property { get; set; } and as a 'regular' property as well. Nothing seems to work, and I can't see what the error is. Bummer :(

Make sure that in SequenceDetector.cs the description property is 'public virtual' as well. I had the same error message but when I change public string Description => ""; to public virtual string Description => ""; it works.

Hm, that does work... but I could have sworn that's exactly what I did first!
