LINQ to SQL is just for SQL Server (and SQL Mobile). LINQ itself is a
very general, nebulous term.

The ADO.NET Entity Framework is a pluggable ORM which incorporates LINQ
and will support drivers for multiple databases.

use Linq with it?

It means you wouldn't be able to use LINQ to SQL with it.

You need to be very precise about what you mean: "LINQ" is too general
a term in this case.

You should be able to use the Entity Framework LINQ provider:

As Jon observes, "LINQ" is a very vague term. For example, NHibernate
is getting a LINQ API; and I'm pretty sure NHibernate supports Oracle.

    I wouldn't hold my breath for that one. I'd be surprised if it is
released before the summer. Writing a full provider (not a toy) is a
lot of work, and even though some work has been done, it's still a lot
of work to get everything implemented.

Fair enough (you're an awful lot closer to that area than me ;-p).

    Within a month you will, using LLBLGen Pro and our linq provider. It
goes into beta this week.
