TechDays - IronRuby
Download as PPTX, PDF0 likes1,040 views
This document provides an overview of the IronRuby programming language and how it allows Ruby code to run on the .NET Common Language Runtime (CLR). Some key points covered include: - IronRuby allows Ruby code to leverage .NET libraries and frameworks like ASP.NET and WPF. - The Dynamic Language Runtime (DLR) plays a key role in enabling IronRuby to run Ruby code on the CLR. - IronRuby makes it possible to embed and extend C# applications with Ruby code through features like MEF. - This merging of Ruby and .NET opens up new possibilities for developers to choose the right language for each task and blend multiple languages together in a single application.

Editor's Notes
- #5: Dynamic language
- #6: Static > Dynamic. Dynamic are more flexible, can adapt the applications frameworks to fit your requirements. Produce similar results, cleaner code and provide a nicer experience for developers. As a result, the code is easier to maintain. Ruby community – testable, clean, natural, expressive => open source
