Hi,

a quick report: when requiring a home-baked C# dll from ruby (require  
‘service.dll’) I get a Ruby.Builtins.LoadError - french error message  
on my machine, but it could mean something like informations about an  
absolute path are required.

In case its useful to newcomers like myself, this can be solved using  
for instance:

require File.dirname( **FILE** ) + “/service.dll”

I guess it is something which will change in the future, right ? Is it  
useful to file a bug for that ?

cheers
