Re: Returning a CLR type from IronRuby

I was talking about this IronRuby group:

http://groups.google.co.uk/group/ironruby?hl=en

It has very little traffic and I am guessing there is a better one?

I have removed the require from the .rb file and my code is below but the
same error persists:

[Fact]
public void Then_a_build_metadata_object_is_returned()
{
   var engine = Ruby.CreateEngine();
   engine.Runtime.LoadAssembly(typeof (Horn.Core.DSL.Domain.BuildMetaData
).Assembly);
   engine.ExecuteFile(buildFile);
   var klass = engine.Runtime.Globals.GetVariable("MetaDataFactory");
   var instance = (RubyObject)engine.Operations.CreateInstance(klass);
   var metaData = (BuildMetaData)engine.Operations.InvokeMember(instance,
"return_meta_data");
   Assert.Equal(metaData.Description, "A description of sorts");
}
