typeof(THandler).GetMethod(nameof(CliAction.InvokeAsync) pattern

[KalleOlaviNiemitalo]

As used in HostingExtensions.UseCommandHandler<THandler>(this CliCommand command):

command-line-api/src/System.CommandLine.Hosting/HostingExtensions.cs

Lines 54 to 60 in b40ebf6

	public static CliCommand UseCommandHandler<THandler>(this CliCommand command)
	where THandler : CliAction
	{
	command.Action = CommandHandler.Create(typeof(THandler).GetMethod(nameof(CliAction.InvokeAsync)));
	return command;
	}

This seems incompatible with explicit override supported by Visual Basic, i.e. where THandler has a method that overrides CliAction.InvokeAsync but is not itself named InvokeAsync.

Besides, GetMethod will fail due to ambiguity if THandler has multiple public methods named InvokeAsync, which is possible in C# too.
