Its good to finally see this being 'a thing' in C#. In my opinion, it is 10 years overdue!
This feature is likely added to compete with Python, Ruby, etc. The fact you just create a file, write some code and run it.
However, I don't see C# being a competitor of said languages even for simple command lines. If anything, it could be a viable replacement to Powershell or maybe F# especially if you need to link it to other .NET DLLs and 'do things'
I am also interested in the performance difference compared to other languages. I mean even Dlang has a script-like feature for sometime, now.. rdmd. Not sure the status of that, but it still compiled and runs the program. Just seems overkill for something rather simple.
This is about education and mindset. Not to enter the space. There might be some people working with it, if they are more relaxed with C# than bash.
Performance right now is horrible (500ms), they promised to improve it, but let us be honest: They are in-memory scaffolding a project, run msbuild restore/reassess/reuse dependencies, and then compile a dll and then load it into a JIT. that is so many more steps than a interpreter will do.

Absolutely...100% !!
