Using ArcGIS Runtime SDK for .NET - Version: 100.1.0.0, I am creating label definitions for various layers, using this documentation: labelingInfo | ArcGIS for Developers
However, I'm unable to determine if there's any property where I can add a leader to the label. Right now, the label is just a rectangle(attached) - I'd like it to have a leader from the left side as part of the label (attached a leader too for better understanding of what I'm talking about). Is this possible using the labelingInfo object, and if so, how do I do it?
