2. Hello, IronRuby!

3. History
Ruby and .NET
Ruby to .NET
Ruby CLR Project
RubyCLR
All attempted to run Ruby on top of the CLR

4. History
CLR 2.0
(.NET 3.0 and 3.5 were still CLR 2.0)
No dynamic dispatch
Everything had to be compiled
Lots of magic, and shims

5. History
CLR 2.0

Type calcType = calc.GetType();
object res =
calcType.InvokeMember("Add",
BindingFlags.InvokeMethod, null,
new object[] { 10, 20 });
int sum = Convert.ToInt32(res);

12. History
DLR
Introduced in 2007
Set of libraries to assist language developers
Still runs on the CLI, and can access the CLR
Standardizes the implementation of dynamic
languages on the CLI/CLR

13. History
IronRuby
John Lam hired by Microsoft in 2006
Announced in 2007 at MIX7
Goal to make Ruby a first-class citizen
Completely rewritten to take advantage of the
DLR
