      var insp = new Inspector();
      insp.LoadSchema(annoLayer);
      // get the annotation properties from the inspector
      AnnotationProperties annoProperties = insp.GetAnnotationProperties();
      // change the annotation text 
      annoProperties.TextString = DateTime.Now.ToLongTimeString();
      // change font color to green
      annoProperties.Color = ColorFactory.Instance.GreenRGB;

      annoProperties.HorizontalAlignment = HorizontalAlignment.Center;
      annoProperties.Shape = pnt;
      // set the annotation properties back on the inspector
      insp.SetAnnotationProperties(annoProperties);
      // create the annotation
      op.Create(annoLayer, insp); 
      if (!op.IsEmpty)
      {

      // use the inspector methodology
      //at 2.x - var insp = new Inspector(true);
      var insp = new Inspector();
      insp.Load(annoLayer, oid);
    
      // get the annotation properties
      AnnotationProperties annoProperties = insp.GetAnnotationProperties();
      // set the attribute
      annoProperties.TextString = "Hello World";
      // assign the annotation proeprties back to the inspector
      insp.SetAnnotationProperties(annoProperties);
    
      //create and execute the edit operation
      EditOperation op = new EditOperation();
      op.Name = "Update annotation";
      op.Modify(insp);
      if (!op.IsEmpty)
      {
        var result = op.Execute(); //Execute and ExecuteAsync will return true if the operation was successful and false if not
