got unexpected named argument error when running csharp code on visual studio

I tried to run the csharp code in Visual Studio Code for Mac, I have scripts installed and added to PATH.
It gives me below error and code cannot run.

[Running] scriptcs "/var/folders/sr/5jzw91rn4g3cc2b0xyhw0j100000gq/T/tempCodeRunnerFile.csharp"
    Unexpected named argument: var/folders/sr/5jzw91rn4g3cc2b0xyhw0j100000gq/T/tempCodeRunnerFile.csharp

This is the question linked: Getting error: /bin/sh scriptcs: command not found

The OS version is 10.14.6(18G87) Please see attached screenshot. Mac OS version

The Visual Studio Code version is below:

Version: 1.38.1

minimal reproducible example:

Open Visual Studio Code and create a new File with below code:

using System;
using System.Collections.Generic;
class Test
{
    static void Main()
    {
        foreach (int fib in Fibs(6))
        Console.Write (fib + " ");
    }
    static IEnumerable<int> Fibs (int fibCount)
    {
        for (int i = 0, prevFib = 1, curFib = 1; i < fibCount; i++)
        {
             yield return prevFib;
             int newFib = prevFib+curFib;
             prevFib = curFib;
             curFib = newFib;
        }
     }
 }

and then click Run Code on top right in Visual Studio Code.

This is a bug in PowerArgs, it recognizes an argument started with slash as an option, so you need split the command into two steps.

cd "/var/folders/sr/5jzw91rn4g3cc2b0xyhw0j100000gq/T"
scriptcs "tempCodeRunnerFile.csharp"

[Update] scriptcs is a csharp code runner, to make it work, at least you need one line to call the entry method.

...

class Test
{
    public static void Main() // Public
    {
        ...
    }
}

Test.Main(); // Run it
