Thanks to Paul Stroffregen and Joe Pasquariello's efforts, I have been able to successfully perform OTA updates to a Teensy 3.5 using Visual Studio 2019 Community Edition and the Visual Micro extension as my Arduino IDE, and a BT link from my laptop to a HC-05 module as the OTA link to the Teensy.
I have placed my demo code on my GitHub site - see this link for the Teensy demo sketch, and this link for the C# command-line program I created to automate the process. I also have a very detailed description of the entire development process (including all my failures!) on my blog site here.
Many thanks to Joe for answering all my dumb questions and helping me understand how his wonderful FlasherX update framework does it's magic. I just hope this demo will help others get over the Teensy OTA hump as well.
Note that at present, the BT OTA process appears to be significantly slower than the manual process using Tera Term. I'm not quite sure why, but I suspect I missed something in my command-line program when initializing the serial link. If anyone can figure that out I'd appreciate the help ;-).
