Yes! Those couple of seconds wait-time are a big bummer for that style of fast-feedback coding (for which there is the built-in `dotnet watch run` by the way).

Made me sad when I was playing around with generative art, where you would really want to see the result of your changes in a split-second.

You can check out ".NET Interactive Notebooks" in VSCode, that executes much faster, but it doesn't do this live watch.
