I tries use "Method To Property" wneh i select get accessor. 
public string Description
       {
           get { return description; }
           set { description = value; }
       }

Trying to use "Convert Method to Property". Actually, I was longer for "Convert Property to Method", but it wasn't available and I tried "Property to Method" just to see if it would work.
