Definitely a bug. I've filed it under http://ironruby.codeplex.com/WorkItem/View.aspx?WorkItemId=1628.

We have an interface defining an event which is implemented by an abstract class in C#. In Ruby, we create an implementation of the abstract class and call only a subset of methods as we require them. The 0.4 version played nicely and would only do the dynamic binding of methods we required at the time we called them, however the latest version of IR seems to try and bind the event (even though we don't hook up to it) and can't find an implementation in ruby so it throws a TypeLoadException citing the adder for the event does not have an implementation. A reproducible case is pasted below. Hoping someone would be able to shed light on whether this is intentional, and if so what we can do to implement the event in ruby. *************************** using System; namespace HelloWorldApp { public interface IHelloWorld { event EventHandler SomeEvent; } public abstract class AbstractHelloWorld : IHelloWorld { public abstract event EventHandler SomeEvent; } } *************************** require "HelloWorldApp.dll" class HelloWorlder < HelloWorldApp::AbstractHelloWorld end @hello_app = HelloWorlder.new #barf *************************** D:\source\dotnet\IronRubyInteropBug>ir ruby_test.rb mscorlib:0:in `_TermCreateClass': Method 'add_SomeEvent' in type 'IronRuby.Classes.AbstractHelloWorld$1' from assembly 'Snippets.scripting, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.
