[Mono-list] Exception using EntityFramework 5

[DrGusman]

Hi. I'm having an exception whenever I try to use entity framework. Have
tried with Sql server and MySQL  providers/db and I get the exact same
error.

The database is the same in Sql server and MySQL, so the resulting entity
model is the same (I puntualize about that because I belive the error is in
the metadata information parsing).

The exception is this:

It's running on mono 4.0.0 compiled from tarball under arm (raspberry).

Everything else works perfectly, any idea on what's going on?

Cheers.
