In System.CommandLine 2.0.0-beta4.22272.1 (commit 209b724), if I set up an option like this
this.jsonDirectoryOption = new Option<DirectoryInfo>(
name: "--json-directory",
description: "Writes API JSON responses to the specified directory.");
this.jsonDirectoryOption.ExistingOnly();
this.Add(this.jsonDirectoryOption);then --help generated a default description for the argument of the option:
--json-directory Writes API JSON responses to the specified directory.
In System.CommandLine 2.0.0-beta4.23165.2 (commit 4d1e6ac), if I similarly set up an option
this.jsonDirectoryOption = new Option<DirectoryInfo>("--json-directory")
{
Description = "Writes API JSON responses to the specified directory.",
};
this.jsonDirectoryOption.AcceptExistingOnly();
this.Options.Add(this.jsonDirectoryOption);then --help does not show that the option requires an argument:
--json-directory Writes API JSON responses to the specified directory.
I can correct the --help output by setting Option.HelpName in my application, but this is quite a surprising change and should at least be documented in the upcoming release notes.
