This challenge may have ambiguous wording. It wants you to create a class in the RepeatDetector.cs file that is a subclass of SequenceDetector. Leave what is in SequenceDetector.cs as is after challenge 1.

try this:

namespace Treehouse.CodeChallenges
{
    class RepeatDetector : SequenceDetector
    {
    }
}

A problem I'm noticing here. You have 

if(sequence[i] == sequence[i - 1]

The first time through the for loop, that would be comparing 

if(sequence[0] == sequence[0 - 1]

See what I mean?
