    public interface ITypeDataSearcher
    {
        /// <summary> Get all types found by the search. </summary>
        IEnumerable<ITypeData> Types { get; }
        /// <summary>
        /// Performs an implementation specific search for types. Generates ITypeData objects for all types found Types property.
        /// </summary>
        void Search();
    }
