Given:

class Options
{
    [Value(0, Required = true)]
    public string Text { get; set; }

    [Option("option", Required = true)]
    public string Option { get; set; }
}

mycmd.exe "test" --option "test"

produces:

ERROR(S):
  A required value not bound to option name is missing.

  --option        Required.

  --help          Display this help screen.

  --version       Display version information.

  value pos. 0    Required.

whereas

mycmd.exe "test1" --option "test2"

works fine.

It's not apparent why passing the same value would cause commandline to behave differently.

This is especially common when you have integer options and values, since it can be common to want to specify 0 or 1 for both an option and a value.

This bug is still present in the latest nuget package (2.1.1-beta), but it looks like it's fixed already in source code.
