[Ironruby-core] Stupid to_clr_string

...oh, if the CLR interface we're calling is typed to System.Object instead of System.String, then we probably can't do any kind of automatic conversion.

Ah, makes sense.  I'm totally unfamiliar with the way IronRuby is implemented. Is it possible to switch it to a clr string any time it calls any framework code? (like the invoke function I'm using).

This isn't a Silverlight issue but an IronRuby one.  A Ruby string simply isn't the same as a CLR string - the Ruby string is mutable while the CLR string is not.



We need to come up with a cohesive plan for dealing with the difference before we can "fix" anything.

Ok, I keep running into this over and over.  Whenever Silverlight passes a string to javascript, it comes out as some unreadable object.  You have to call to_clr_string to get it working.



This is ok... You can monkey patch some of the javascript library code to fix it, but with HtmlPage.window.invoke, for example, it's not easy to do because it sends a variable number of arguments.



Is this being fixed? Or is this something we're going to have to deal with for a while?



Thanks
