What do you do when you attempt to Check your Work and you keep getting a time-out error for the TreeHouse service?

I am at the point of adding a GetHasCode override and checking my work does not do anything. I have waited, refreshed and retried 5 times now...

VocabularyWord.cs
using System;
namespace Treehouse.CodeChallenges
{
    public class VocabularyWord
    {
        public string Word { get; private set; }

        public VocabularyWord(string word)
        {
            Word = word;
        }

        public override string ToString()
        {
            return Word;
        }

        public override bool Equals(object obj)
        {
            if(!(obj is VocabularyWord))
            {
                return false;
            }

            var that = obj as VocabularyWord;

            return this.Word.Equals(that.Word);
        }

        public override int GetHashCode()
        {
            return this.GetHashCode();
        }
    }
}

When you call "this.GetHashCode" the method is calling itself, which sets up a recursion loop that never ends.

Perhaps you intended to call "this‍.Word‍.GetHashCode()" instead?
