Hi,

I’m trying to load an IronPython file in IronRuby (via IronRuby.require)  
and  
I get an exception: “Failed to load language ‘IronPython 2.6’: type  
‘IronPython.Runtime.PythonContext’ is not a valid language provider  
because  
it does not inherit from LanguageContext”.

This is thrown from the require method.

What am I doing wrong?

Thanks,  
Shay.

Looks like version mismatch. Do you build IronPython from the same  
sources as IronRuby?  
You can find compatible binaries here:  
[http://ironruby.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=33693](http://ironruby.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=33693)

You’re right. I had to build IronPython to make it work.  
I didn’t realize IronPython was part of the source until now 🙂

Thanks!  
Shay.
