Hey folks, I downloaded DLR from [dlr.codeplex.com](http://dlr.codeplex.com) a few days ago and IR was not properly using CWT to store properties on CLR objects. Has this been fixed? ---

No, IronRuby still uses a custom weak table, which doesn’t work properly in all scenarios.

That’s pretty odd given that there is code to transparently use CWT instead of Dictionary\. I was hoping for to use IR to benchmark my current implementation of CWT on mono. ☹ On Thu, May 6, 2010 at 2:21 PM, Tomas M. \ **Author:** ![Rodrigo\_Kumpera](https://www.ruby-forum.com/letter_avatar_proxy/v4/letter/r/ea666f/32.png) [@Rodrigo\_Kumpera](https://www.ruby-forum.com/u/Rodrigo_Kumpera)\ **Post date:** [May 11, 2010, 5:57am UTC](https://www.ruby-forum.com/t/ironruby-usage-of-conditionalweaktable/188162/4 "2010-05-11T05:57:40Z") Don’t rush at finishing it just because of me. Specially because the managed part of our CWT is doing linear search instead of been a hashtable. I’m halfway thru implementing it and it would be awesome to have it done since most of my tests are artificial.

I can look at doing so tomorrow if it helps you.
