This may be a silly question but I was under the impression that it was possible to use IronRuby and MS Visual Studio 2010 together to sort of build interfaces\\edit XAML in one
In order to build GUIs you should use XAML with WPF. You can create XAML with the editor in Visual Studio. Running a XAML file is possible with:
require "PresentationFramework"
include System::Windows
include System::Windows::Markup
xaml = File.Open('d:/app/window1/xaml', "r").read
@root = System::Windows::Markup::XamlReader.parse(xaml)
app = System::Windows::Application.new
app.run @root
Please refer to IronRuby Unleashed for more information
