Csla.Luna, what is it?

I have this wpf form; the call InitializeComponent()

brings up this message:

A binding error was detected.

The assembly with the display name "Csla.Luna" was not loaded into the Binding Context "Load" AppDomain with the identifier 1. The reason for the failure was: System.IO.FileNotFoundException: it is possible not to load the file or assembly "Csla.Luna, Version = 3.6.1.0, Culture = neutral, PublicKeyToken = 93be5fdc093e4c30 'or one of its dependencies.

We are using Csla, but in a data access component not developed by me; I don't know what Csla.Luna is and I couldn't find anything on the internet. Any help? ...

The only "normal" thing I do on this form is that I bind to some ObjectDataProviders that call static methods that access the database but have worked so far and I can't tell if this is the problem or not.

Any help would be greatly appreciated. Can't believe Google has no idea about this Csla.Luna thing.
