body: <p>I get the error "Cannot implicitly convert type 'string' to 'bool'.  How do I return 'Yes' or 'No' instead of true/false?</p>
  
  <pre><code>public bool? BuyerSampleSent

      get { bool result;
            Boolean.TryParse(this.repository.BuyerSampleSent.ToString(), out result);
          return result ? "Yes" : "No";
      }
      set { this.repository.BuyerSampleSent = value; }
