The folder SL is installed into is the version; if you're using SL2 it should be C:\Program Files\Microsoft Silverlight\2.0.40115.0\. SL3 Beta is C:\Program Files\Microsoft Silverlight\3.0.40307.0\.
http://jimmy.schementi.com/silverlight/repro-defined.zip Unzip that and double-click on the index.html file. The first line of app.xap is defined?(System::Windows::Forms), and works fine. It also works in the console. Let me know what happens for you. ~js From: ironruby-core-boun...@rubyforge.org [mailto:ironruby-core-boun...@rubyforge.org] On Behalf Of Thibaut Barrère Sent: Thursday, April 02, 2009 2:57 AM To: ironruby-core@rubyforge.org Subject: Re: [Ironruby-core] defined?(xxx) behaves differently when called from Silverlight Hi, I believe I need to give you more context about what I'm doing. In Magic (see here<http://github.com/thbar/magic/blob/faf98c3161221e309290e7a6e311adb27fddf825/lib/magic.rb#L32> in particular) I currently have a single file providing support for WPF, Silverlight and Windows Forms. I use defined? to determine if one of these are available and adopt adequate behaviour. So that's why I run defined?(System::Windows::Forms::Control) inside Silverlight. I can definitely think about alternatives (such as creating a specific file for each scenario) - I could do that but I'm trying to stay with a single file and avoid metaprogramming for the moment as it's much simpler to test. So back to the issue, now that I hope you have a clearer understanding of what I'm doing here. Using ruby 1.8.6 or ironruby v0.3, running this file through command line [ruby/ir] my_test.rb doesn't choke: raise "detected!" if defined?(System::Windows::Forms::Control) Putting the same code as the first line of app.rb in a silverlight ironruby app fails: MemberAccessException: uninitialized constant System::Windows::Forms Is there any way to retrieve some accurate info on versioning from inside silverlight, so that I can make a better report or understand what's happening ? -- Thibaut
