Add additional Data Providers to VS C# Express??

Is it possible to add additional Data Providers/Data Sources to the Express
editions, as I'm trying to connect to an Interbase Server.

The only two providers available are SQL Server and Access... at present,
I'm having to connect the Access to Interbase via ODBC, then connect VS to
the Access DB. I've installed a .NET Data Provider for Firebird, which
allows me to connect directly in Code, no problem.

It's just the designer is giving me problems and it's very frustrating.
