The release on DLR CodePlex is broken. We are working on a fix. The problem is in signed assemblies. Removing ir.exe.config (located next to ir.exe) might help.

Subject: [Ironruby-core] how to initialize iron ruby from c#

Hi there,

I am trying to initialize an iron ruby engine for execution of code snipptes from a c# application. extensive googling has not helped me with the task because there seem to have been much changes in iron ruby lately.

Here is my code:
var runtime = Ruby.CreateRuntime();
var engine = m_runtime.GetEngine("IronRuby"); // <--- InvalidImplementationException is thrown here

This is the inner exception.

{"Could not load file or assembly 'IronRuby.Libraries, Version=, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.":"IronRuby.Libraries, Version=, Culture=neutral, PublicKeyToken=null"}

This happens with the latest nightly build of DLR binaries. I did make sure that IronRuby.Libraries.dll is added in the References of the project but it still can't be loaded. Did I miss something obvious?

Any help would be much appreciated.
