Dynamic line when drawing from one vertex to another

Question

We would like the ability to see the line when connecting two vertices of a polygon (before creating the new vertex). Our old application using 10.2.7 seems to have this functionality but I can't find it using 100.1 does not. I have searched everywhere without any luck.

Is there a way to activate this functionality in the MapView or in the SketchEditor?

I guess I replied to myself instead of you. I posted a response below that I am now getting a null reference exception.

I am now getting this issue Completing the SketchEditor with a double click sometimes causes the application to crash

I am using the solution above along with attaching to the GeoViewDoubleTapped event to handle completing the draw action.

I found that the GeoViewTapped event fires before GeoViewDoubleTapped (obviously). The issue that I am seeing is that InsertVertexAfterSelectedVertex is executed fine, then when the GeoViewDoubleTapped is fired it completes the sketch. Something with the runtime is taking so long to complete the InsertVertexAfterSelectedVertex method call that the sketch actually completes before the vertex is added. Which causes the error that is noted in the link above

Is that if adding a vertex is asynchronous? If it is, then we need the ability to await that method.

Awesome, I was hoping it would be a property but this is simple enough. Thanks!
