Do these problems manifest when using IronRuby 1.1.2? (master from
github). Could you file a bug with details if so?
Thanks,
Tomas

It seems that Cucumber for IronRuby is a little broken at the moment.
There’s an issue with Gherkin (the bdd language used by Cucumber and
SpecFlow).
To get around this, I installed an older version of Cucumber that did
not have this dependency.
I installed Cucumber 1.6.4 with the command:
igem install cucumber -v=1.6.4
It needed iron-term-ansicolor, I installed that with:
igem install iron-term-ansicolor
To get Cucumber to run with IronRuby, I created a batch file in the
IronRuby bin folder called icucumber.bat. My bat file looks like:
@ECHO OFF
REM This is to tell IronRuby where to find gems.
SET
GEM_PATH=C:\Users\mike.hatfield.NICOM.pik\rubies\IronRuby-10v4\lib\ironruby\gems\1.8
@“C:\Users\mike.hatfield.NICOM.pik\rubies\IronRuby-10v4\bin\ir.exe”
“C:\Users\mike.hatfield.NICOM.pik\rubies\IronRuby-10v4\bin\cucumber” %*
Your batch file’s GEM_PATH and executable paths are probably different
than mine, I’m running IronRuby with PIK (allows me to run multiple
versions of Ruby).
I then started the feature from the MSDN article. I had to change
“Story:” to “Feature:”. My story is:
Feature: Pricing for New Product X
As a sales administrator, I want to be able to view
prices for product x so that I can provide customers
with an accurate cost for their requirements.
Scenario: Single User License for Product X without support
Given Product X
When user requests a 1 user license
And this does not include support
Then the price should be $250
I called this file story.feature and saved it in a folder called
features.
If you run the following cucumber command, you should get the initial
cucumber story run.
icucumber features
This gives you a list of steps (When clauses) that need to be
implemented in your step definitions to make the story pass.
Inside the features folder I created another folder called
step_definitons. Inside the step_definitons folder, I created a file
called product_steps.rb
Now, for the .NET class library. I created three class files:
Product.cs
namespace Bdd.Store
{
public class Product
{
public string Name { get; set; }
public double Price { get; set; }
}
}
Store.cs
namespace Bdd.Store
{
public class Store
{
public Product FindByProductName(string name)
{
Product product = new Product { Name = name };
return product;
}
}
}
Purchase.cs
namespace Bdd.Store
{
public class Purchase
{
public Product Product{ get; set; }
public int Licenses { get; set; }
public bool IncludesSupport { get; set; }
public double GetTotalPurchasePrice()
{
double price = Product.Price * Licenses;
double supportFees = 0.0;
if(IncludesSupport)
{
supportFees = price * 0.10;
}
return price + supportFees;
}
}
}
I then compiled these into an assembly called Product.dll using the
CSharp compiler command (run from my Visual Studio Command window):
csc /out:Product.dll /target:library Product.cs Store.cs Purchase.cs
I then required my Product.dll into my step definitions file
(product_steps.rb)
require File.dirname(FILE) + “/Product.dll”
Just as a convenience, I “include” my Bdd.Store namespace:
include Bdd::Store
I also require RSepc
require “rspec”
Lastly, I begin implementing my steps:
Given /^Product (.*)$/ do |product|
@store = Store.new
@product = @store.find_by_product_name(product)
@product.price = 250;
@product.name.should == product
end
and so on and so forth. You can download my files from

CSharp.ziphttp://webcoding4fun.oakraven.net/downloads/BDD%20Example%20with%20CSharp.zip
I hope this helps a little.
