What am I doing wrong? Why isn't the hashcode returning?

using System; namespace Treehouse.CodeChallenges { public class VocabularyWord { public string Word { get; private set; }
public virtual int GetHashCode()

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

    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);
    }
}

}

VocabularyWord.cs 
using System;
namespace Treehouse.CodeChallenges
{
    public class VocabularyWord
    {
        public string Word { get; private set; }    
        public virtual int GetHashCode()

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

        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);
        }
    }
}

Well I have noticed that you have two GetHashCode() methods with the same signature in the class. Just remove that virtual one which is also missing parenthesis {}.

    public class VocabularyWord
    {
        public string Word { get; private set; }


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

        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);
        }
    }
