Checks:
- Checked the file permissions and I have `drwxr-xr-x` in `bin/Debug/net5.0` and `obj/Debug/net5.0` and my user is the owner of the folders

The code in my Program.cs

```csharp
using System;
using System.CommandLine;
using System.CommandLine.Invocation;
using System.IO;

namespace HelloWorld
{
class Program
{
static int Main(string[] args)
{
var rootCommand = new RootCommand("Hello world CLI with System.CommandLine")
{
new Option(
"--int-option",
getDefaultValue: () => 42,
description: "An option whose argument is parsed as an int"
),
new Option(
"--bool-option",
"An option whose argument is parsed as a bool"
),
new Option(
"--file-option",
"An option whose argument is parsed as a FileInfo"
)
};

rootCommand.Handler = CommandHandler.Create((intOption, boolOption, fileOption) =>
{
Console.WriteLine($"The value for --int-option is: {intOption}");
Console.WriteLine($"The value for --bool-option is: {boolOption}");
Console.WriteLine($"The value for --file-option is: {fileOption?.FullName ?? "null"}");
});

return rootCommand.InvokeAsync(args).Result;
}
}
}
