iron* - an introduction to getting dynamic on .net
DESCRIPTION
In recent years dynamically typed languages have received more and more attention on the .NET platform. Initially, an implementation of Python showed up. Later, the Dynamic Language Runtime (DLR) appeared which made it much easier to implement dynamically typed languages on .NET. This session explores how dynamically typed languages fit in the ecosystem of .NET. We’ll see why dynamic languages are interesting and contrast them to their static brethren (C#, Java). Then we will touch on how IronPython and IronRuby are implemented on .NET via the Dynamic Language Runtime (DLR). Finally, we’ll look at some code examples of how you can utilize these languages on .NET today.TRANSCRIPT

Why Dynamic Languages
Simplicity
Expressive Perspective
The traditional view of the world
Dynamic Languages
Simple and succinct
Implicitly typed
Meta-programming
No compilation
Static Languages
Robust
Performance
Intelligent tools
Better scaling
Dynamic Language Runtime
Dynamic Languages on .NET
IronPython IronRuby
C# VB.NET
Common Language Runtime
Iron?
Multiple Language Dynamic Dispatch
Object Binder
Python Binder
Ruby Binder
COM Binder
Dynamic Language Runtime
GetMember Name=“Foo”, IgnoreCase=false
IronPython x.Foo
IronRuby x.Foo
C# x.Foo
VB.NET x.Foo
Common Language = CLR + DLR
