What is IronRuby

The Ruby VM implemented in .Net (C#)

Part of the family of the scripting (and not only) languages implemented in .Net Python Ruby (more coming)?

.Net Integration

Interoperability with .Net Consume all the C# code you want!

The huge .Net library ecosystem External .Net libraries Custom / existing C# code

# Demo

.Net Integration

Extend existing .Net classes the ruby way!

.Net Integration

Call ruby code from .Net!

# Demo

.Net Integration

Deploy on .Net infrastructure Web apps on IIS (Rails on .Net!) Consume (natively) .Net services

SQL Office Active Directory Exchange etc...

.Net Integration

Deploy on .Net infrastructure Desktop applications on Windows Desktop applications on everywhere

(Mono)

.Net Integration

Test .Net code with Cucumber & RSpec!

Additionally

“Translations” of idioms: object.SomeMethod() <->

object.some_method System.Core <-> System::Core

C# lambdas and delegates <-> Ruby clojures

>>> l = System::Byte.instance_methods(false).last=> 'get_type_code'

>>> l.ruby_name=> "get_type_code"

>>> l.clr_name=> "GetTypeCode"

Additionally

Interoperability with the other scripting languages! Python JavaScript …

Use code also from there!

Silverlight

Silverlight integration Write ruby instead of javascript in

your pages! (Gestalt project)

# Gestalt Demo

Limitations

No support for native C gems Some rough edges in interoperability
