That worked! That would be a fun bug to track down. 🙂

I was worried that it was reflection against an attribute, because the  
documentation on the IR site seems to suggest that attributes still  
aren’t  
supported in .net API interop. (  
[http://ironruby.net/Documentation/.NET/API\_Guidelines](http://ironruby.net/Documentation/.NET/API_Guidelines))

Thanks again!

That’s a bit ambiguous.  
If your C# library uses attributes I don’t see why you wouldn’t be able  
to  
reflect over those types with IronRuby and execute the attribute.

But using attributes in Ruby that is a totally different story. Luckily  
ruby  
has a different idea about classes and you can use class methods to  
reach a  
similar effect.  
For example [ASP.NET](http://ASP.NET) MVC uses attributes to do its job, but IronRubyMvc  
has  
no need for them because it uses those class methods.
