Re: [IronPython] Loading Python modules from Silverlight Isolated Storage

Another option, assuming it's possible, would be to exec the function definition as well as the lambda. Also I would expect exec ... in locals() would work the same as "in dict(locals())". Which might also be problematic if you expect to see changes in the closure: def f(): a = 1 d =

Re: [IronPython] Question Regarding WPF : DataBinding, DataTemplates and C# Extensions

Michael is right. The control still does have some limitations. When I finish my IronRuby book I'll look at changing some of the implementation. At this moment you would need a create a formatter for ironpython You can view the RubyFormatter here: http://code.google.com/p/dynamic-script-control/s
