EditOperation.Delete() fails

Question

I am playing with the ArcGIS Pro SDK, and got stuck when trying to delete a feature from a featureclass using an EditOperation. While FeatureClass.DeleteRows() works fine, the following code throws an error: No parameterless constructor defined for this object. var result = await QueuedTask.Run(() => { using (var gdb = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(@"C:\Data\Test.gdb")))) { var fc = gdb.OpenDataset<FeatureClass>("punten"); var cursor = fc.Search(null, false); if (cursor.MoveNext()) { var editOp = new EditOperation { Name = "Een test" }; editOp.Delete(cursor.Current); return editOp.Execute(); } return false; } });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Also, modifying a feature works perfect: editOp.Modify(cursor.Current, "test", "Hello");‍‍ Am I missing something?

The best practice is definitely to call Dispose on Row and Feature objects.  Keeping these objects around in memory can cause the system to hold onto file handles or database connections.

Yes, thanks for the reminder about disposing objects.

I was wondering, are Row and Feature objects meant to be short lived, or is it OK to keep them in memory? What are the best practices?

Yes, working on a MapMember works. In this case though, I was trying to edit a featureclass that was not added to a map.
