private static object _SyncLock = new object();
 
public TableInfo<TEntity> TableInfo
{
  get 
  {
      if (_TableInfo == null)
      {
          lock (_SyncLock)
          {
              if (_TableInfo == null)
                _TableInfo = new TableInfo<TEntity>();
          }
      }
 
      return _TableInfo; 
  }
  set { _TableInfo = value; }
}
private static TableInfo<TEntity> _TableInfo = null;
