Hi all,
I am trying to test out v.5.0, and I downloaded the trial, but when I try to add a table from an oracle DB that we have running here, I receive the error: unable to cast object of type system.null to system.string

It doesn't give any more info than this. Has anyone seen this before, and if so, is there a fix for it.

Ok, I was able to generate an entity model using the devArt developer, which worked very well. Is it better to use the external tool, or should I be looking to use it within VS 2008?

The only way to work with LINQ to Oracle at the moment is to use Entity Developer.
We are working on Visual Studio integration, but no timeframe can be available.
