    Example
    Edit Operation Create Features
    var createFeatures = new EditOperation() { Name = "Create Features" };
    //Create a feature with a polygon
    var token = createFeatures.Create(featureLayer, polygon);
    if (createFeatures.IsSucceeded)
    {
      // token.ObjectID wll be populated with the objectID of the created feature after Execute has been successful
    }
    //Do a create features and set attributes
    var attributes = new Dictionary<string, object>();
    attributes.Add("SHAPE", polygon);
    attributes.Add("NAME", "Corner Market");
    attributes.Add("SIZE", 1200.5);
    attributes.Add("DESCRIPTION", "Corner Market");
    
    createFeatures.Create(featureLayer, attributes);
    
    //Create features using the current template
    //Must be within a MapTool
    createFeatures.Create(this.CurrentTemplate, polygon);
    
    //Execute to execute the operation
    //Must be called within QueuedTask.Run
    
    if (!createFeatures.IsEmpty)
    {
      createFeatures.Execute(); //Execute will return true if the operation was successful and false if not.
    }
    
    //or use async flavor
    //await createFeatures.ExecuteAsync();
    
    Create feature from a modified inspector
    var insp = new ArcGIS.Desktop.Editing.Attributes.Inspector();
    insp.Load(layer, 86);
    
    ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>

      var createOp = new EditOperation() { Name = "Create from insp" };
      createOp.Create(insp.MapMember, insp.ToDictionary(a => a.FieldName, a => a.CurrentValue));
    
      if (!createOp.IsEmpty)
      {
        var result = createOp.Execute(); //Execute and ExecuteAsync will return true if the operation was successful and false if not
      }

    Create features from a CSV file
    //Run on MCT
    ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>

      //Create the edit operation
      var createOperation = new ArcGIS.Desktop.Editing.EditOperation() { Name = "Generate points", SelectNewFeatures = false };
    
      // determine the shape field name - it may not be 'Shape' 
      string shapeField = layer.GetFeatureClass().GetDefinition().GetShapeField();
    
      //Loop through csv data
      foreach (var item in csvData)
      {
    
        //Create the point geometry
        ArcGIS.Core.Geometry.MapPoint newMapPoint =

        atts.Add("FacilityID", item.FacilityID);
        atts.Add(shapeField, newMapPoint);
    
        // queue feature creation
        createOperation.Create(layer, atts);
      }
    
      // execute the edit (feature creation) operation
      if (createOperation.IsEmpty)
      {
        return createOperation.Execute(); //Execute and ExecuteAsync will return true if the operation was successful and false if not
      }
      else
        return false;
    });
    Edit Operation Duplicate Features
    {
      var duplicateFeatures = new EditOperation() { Name = "Duplicate Features" };
    
      //Duplicate with an X and Y offset of 500 map units
      //At 2.x duplicateFeatures.Duplicate(featureLayer, oid, 500.0, 500.0, 0.0);
    
      //Execute to execute the operation
      //Must be called within QueuedTask.Run
      var insp2 = new Inspector();
      insp2.Load(featureLayer, oid);
      var geom = insp2["SHAPE"] as Geometry;
    
      var rtoken = duplicateFeatures.Create(insp2.MapMember, insp2.ToDictionary(a => a.FieldName, a => a.CurrentValue));
      if (!duplicateFeatures.IsEmpty)
      {
        if (duplicateFeatures.Execute())//Execute and ExecuteAsync will return true if the operation was successful and false if not
        {
          var modifyOp = duplicateFeatures.CreateChainedOperation();
          modifyOp.Modify(featureLayer, (long)rtoken.ObjectID, GeometryEngine.Instance.Move(geom, 500.0, 500.0));
          if (!modifyOp.IsEmpty)
          {
            var result = modifyOp.Execute();
