Shebang not working with runtime directive in script file

I’m trying to play around with using these scripts, and I’m attempting to allow the file to be run directly from the terminal, however whenever I use the shebang and runtime directive together, I get the following error message:

test.csx(2,1): error CS1024: Preprocessor directive expected

I’m using the following script:

#! /usr/bin/env dotnet script
#! "netcoreapp2.1"

Console.WriteLine("Hello world");

If I remove the runtime directive, using ./test.csx works fine, and if it remove the shebang instead, then dotnet script test.csx works fine, it’s just when both are present, dotnet script seems to not like it. I’ve tried putting the shebang in with double quote around it, but then dotnet script just tries to load that as a runtime, and it doesn’t seem to work out.

We should maybe consider scaffolding the shebang on *nix. We already set up the omnisharp.json during dotnet script init so OmniSharp will be happy either way

#345 is new PR for this (I messed up the branch for #341. 2 things to make shebang work:

1. just add the single directive !#/usr/bin/env dotnet-script
2. mark the file as executable with chmod +x foo.csx
3. make sure file doesn’t have Byte Order Mark (BOM) and has Linux LF, not windows

That works even without the PR. The PR is simple to make the Dotnet script init scaffolding do that by default.
