Hi As you''ve probably seen before I''d like to write a couple of articles that show how to use ironruby with a couple of .NET ORMS but in the process of writing those I get constantly tripped up. When I have to pass a type parameter it looks like it loses some of it''s inheritance information at least that is the case with lightspeed. I can do without LightSpeed so atm this is no problem for me When I want to use Linq 2 Sql I need to pass a type of block Func<T, bool> to the where expression db.categories.where {|c| puts c.name } But IronRuby doesn''t like it that much. So the question is how exactly do I use System::Enumberable.Where etc? I haven''t gone further trying other ORM''s yet.
