The Silverlight Dynamic Languages SDK is available on CodePlex.

From http://github.com/casualjim/ironnails/tree/master:

“IronNails is a framework inspired by the Rails and rucola frameworks. It offers a rails-like way of developing applications with IronRuby and Windows Presentation Foundation (WPF).
This framework uses the pattern Model – ViewModel – View – Controller (M-VM-V-C). It should be able to run on both WPF and Silverlight.
The idea is that the views can be created using a design tool like Blend for example and just save that xaml as is. The designer should not need to use anything else than drag and drop to create a GUI design. The behaviors are then added to the view by using predefined behaviors in the framework or by defining your own behavior.
The framework then generates a proxy for the view which will be used to transparently wire up the commands in the behaviors to controller actions.”

From the Jimmy Schementi‘s blog:

“silverline is a Ruby on Rails plug-in which gives the ability to run Ruby in the browser to manipulate HTML, vector graphics, or just do some computation. Bottom line: it let’s you write Rails code that can run on the client.”

The new release is available for download.

Thanks to this post by Marco Cantù, I’ve found two interesting articles by Justin James about the future of the Embarcadero/CodeGear development environments:

• CodeGear: Working hard to rejuvenate its legacy;
• CodeGear: Extending the Borland legacy to Ruby and PHP developers.

Justin states that ”CodeGear’s .NET products are expanding in new directions, which include RIA development and targeting other platforms (through systems such as Mono)”.

Will we be able to write rich internet applications using Delphi and targeting both .NET and Mono platforms?

Thanks to WinApse I’ve found these useful resources about Unit Testing and Silverlight:

• Unit Testing with Silverlight 2, by Jeff Wilcox;
• Unit Testing Asynchronous Silverlight code, by Jonas Follesoe;
• Source Code and Unit Tests for Silverlight 2 Beta 1 Controls.

Some interesting and introductory material about Unit Testing is also available in the following books:

“IronPython in Action” by Michael J. Foord and Christian Muirhead

“IronRuby in Action” by Ivan Porto Carrero

John Lam has posted the news: Rails runs on IronRuby.

So Microsoft supports Open Source, you’ll be able to write .NET applications in IronRuby, and Rails applications will have access to all the powerful characteristics of the .NET framework (Silverlight, WPF, ASP.NET, just to list a few examples).

Check out the project Home Page on RubyForge!
