This is for everybody’s information:

If you’re hosting IronRuby in a C# application then your code is likely  
to  
break with IronRuby HEAD

The RubyContext class has gone away and the RequireRubyFile extension  
method  
has been renamed.

var setup = new ScriptRuntimeSetup();  
setup.LanguageSetups.Add(Ruby.CreateRubySetup());  
var scriptRuntime = Ruby.CreateRuntime(setup)  
var loadPaths = new List{ “lib”, “bin” };

var engine = Ruby.GetEngine(scriptRuntime);  
_engine.SetSearchPaths(loadPaths);_  
_engine.RequireFile(“my\_library”);_

This means that you can’t currently use ironrubymvc and ironnails with  
HEAD

These are intentional API changes for v1.0. Do you have any scenarios  
where you need to get RubyContext?

## No that was just a heads up for other people. After having spent some time finding out why my markup extensions wouldn’t work anymore. I like this API better.
