I second the 'any 3rd party provider' option. I'd love to use LinqPad with Postgres (for those of you who don't know yet - Postgres has the best features of both MySQL and Oracle).

Why not start with System.Data.Sqlite? It supports LINQ and Entity Framework: http://sqlite.phxsoftware.com/

MySQL

Oracle support would be great

MySQL is very well supported using the EntityFramework...

simply add Datacontext by DLL... there you go... very easy... i even think that Oracle is supported this way too, heck the EntityFramework supports Oracle + MySQL

I'm using Entity Framework to MySQL and it would be great to use LinqPad to query that database. Otherwise, I'm not going to really be able to use Linqpad :-(.

MySQL support would be fantastic... My employer runs .NET solutions on MySQL and I have been using Entity Framework on one of my projects recently. I'd love to be able to load my EF context into LINQPad.

SqLite has a VS2008 provider that allows VS to create entity models from the database, so all one has to do is build the data context in VS and then LinqPad should be able to hook right up to it

How about just third party EF Providers? They all should be able to load dynamically using the EF interfaces, that was the whole point of EF.

Of course my vote is for VistaDB support (we are adding EF in the next release and LINQPad would be a great tool for our users).

it would be nice to have oracle provider beside MS SQL

Oracle Support would be great though its a widely used and highly sophisticated db-engine.

The more backends you could support the better. MS Access should probably be right up there also.
