How to use Verbs in combination with inheritance?

[dasdingo]

When trying to have 2 verbs which inherit from a base class i get the following error:

System.InvalidOperationException: Sequence contains more than one matching element

Is inheritance of option classes not supported at the moment?

Can you post the relevant options classes? Quick glance says you might be duplicating verb names in the child class, but it's hard to tell without a sample.

Code Extract:
Baseclass:
public class CommandLineOptions
{

	[Option('m', "ma", Min = 3,Max = 3, HelpText = "[]")]
	public IEnumerable<string> InputTypes { get; set; }
    }

child class:

public class ListGeneratorCommandLineOptions : CommandLineOptions
{
public enum GenType
{
dat
}

	[Option('g', "gentype", Required=true, HelpText = "File Generation.")]
	public GenType GenerationType { get; set; }

In Main:

var result = Parser.Default.ParseArguments(args);

What version of the library? I'm using the latest beta and it works fine (although you need to explicitly specify the options type you are parsing: Parser.Default.ParseArguments<ListGeneratorCommandLineOptions>(args))

[dasdingo]

I used version 2.0.0.0 before. Now I am using 2.0.275.0 and everything works fine! Thank you very much!
