[Ironruby-core] Getting started with IronRuby and c# issues.

[John Nolan]

Hi IronRuby mailing list,

Inspired by a talk by Ben Hall on testing c# with Ruby I thought I'd give it
a go but
I'm frustratingly stuck at the first hurdle. I've emailed Ben but as I've
not had an immediate response I thought I'd open it to you good people.

Any way. I thought I'd start off simple and follow Dom Green's blog.
domgreen.com/2010/02/07/pumping-iron-ruby-net-testing/

He's set a class in c# with a simple property (here's mine)

namespace IronRubyAndCSharp
{
    public class Person
    {
        public string FirstName { get; set; }

        public Person(string name)
        {
            FirstName = name;
        }
    }
}

and tested it like so

require "test/unit"
require "../IronRuby/bin/debug/IronRubyAndCSharp.dll"

class PersonTest < Test::Unit::TestCase
include IronRubyAndCSharp
  def test_create_person_called_john
    john = Person.new("John")
    assert_not_nil(john)
    assert_equal("John",Person.FirstName)
  end
end

RubyMine(RM) has no problem with the require of the dll but it does have a
problem recognising the namespace "IronRubyAndCSharp"
and the Person class (squiggly lines ahoy).

When I run the tests in RM I get

NoMethodError: undefined method `FirstName' for
IronRubyAndCSharp::Person:Class
C:/Users/John/Documents/IronRuby/Tests/Person_test.rb:14:in
`test_create_person_called_john'

Just in case RubyMine was at fault I dropped out to good old ir.exe

C:\Users\John\Documents\IronRuby\Tests>ir Person_test.rb --name

I've stuck my code up on github
http://github.com/johnnonolan/IronRubyAndCSharp if you feel that was
inclined.

Any pointers, help or whatever much appreciated.
