Ok. I give up. I cannot for the life of me getting a simple IronRuby Silverlight project to debug. I am using VS2008 SP1 and the Silverlight 3 Tools. These are my steps: - Create website using chiron. - Set the initparams to debug=true,reportErrors=errorLocation - F5 These last steps I have tried in every order under the sun. - Set a breakpoint in my app.rb file - Attach to browser - Refresh browser No matter what I do I always get that empty circle with a question mark for my breakpoint like the symbols never get loaded. I have tried using both Casini and Chiron when trying to be debug, but nothing works. I also tried selected the Silverlight checkbox in the website settings for the debugging and still nothing. Please help. Thanks, Randall ---

Randall, It’s a bug; we were not emitting PDBs in Silverlight, by mistake ([http://ironruby.codeplex.com/WorkItem/View.aspx?WorkItemId=3423](http://ironruby.codeplex.com/WorkItem/View.aspx?WorkItemId=3423)). This will be checked in shortly and fixed in the next release. If you want to fix this yourself now, just remove the “#if !SILVERLIGHT” and corresponding “#endif” from RubyScriptCode.CompileLambda([http://github.com/ironruby/ironruby/blob/master/Merlin/Main/Languages/Ruby/Ruby/Runtime/RubyScriptCode.cs#L124](http://github.com/ironruby/ironruby/blob/master/Merlin/Main/Languages/Ruby/Ruby/Runtime/RubyScriptCode.cs#L124)), then rebuild IronRuby for Silverlight: msbuild Merlin/Main/Languages/Ruby/Ruby.sln /p:Configuration=“Silverlight Debug” /p:SilverlightPath=“C:\Program Files\Microsoft Silverlight\3.0.40818.0” (make sure that path to Silverlight is correct for you). ~js
