ADO.NET Data Services enables an application to intercept request messages so that you can add custom logic to an operation. You can use this custom logic to validate data that goes to the client or returns to be persisted on the server.

LinqPad is a nice and popular query analyzer made to test LINQ queries: whether it is Linq To Sql, Linq to Objects or some other flavor, you will be able to play in a nice way with it.
