Hi ProgrammerBret,
Thank you for posting here.
>>My question is whether I should use .net core 3 in VS 2019 when it becomes available, and whether this would still require me to install Mono on the Pi in order to run the .exe on a schedule, or will this not work ?
I only tell you that you could use .net core 3.0, because I am not familiar with Raspberry Pi 4 or Mono. Also, it is a hardware product, we don't support.
Therefore, I suggest that you could ask it in the following link.
https://developercommunity.visualstudio.com/spaces/61/index.html
The Visual C# forum discusses and asks questions about the C# programming language, IDE, libraries, samples, and tools.
Best Regards,
Jack
