Now I'm curious if C#/.Net 10 is smart enough to ignore the shebang line. Personally, I've tended to use Deno/TS for my more advanced shell scripting... the main runtime is a single executable that works fine in user context, and dependencies can be loaded/cached at first run.

Of course, with C# as a shell script, you'd likely be limited to just in the box libraries or have to setup a project for sake of running a script, like I've had to do with Node or Python stuff.
