yep that is correct :) http://github.com/casualjim/ironnails/tree/master/IronNails/vendor/iron_nails/lib/core_ext/kernel.rb
I figure you can wrap that in a begin..rescue block again and first try the one with the bool and then the one without it. Some implementations of Dispose don't actually implement the method with a bool as parameter. Instead of FileStream you can use the ruby File class or you could write a FileStreamAdapter in C# or something so you can safely use it from IronRuby without the overloading mayhem.
