Firebird - nice, scalable open source database with one of the best freeware .NET integration.

Answer 4

PostgreSQL is licensed under a BSD license, which makes it an obvious choice if your product is commercial. That, and it's a very good database management system.

SQLite also has a friendly licesnse, but it is very different from a traditional SQL DBMS.

Answer 5

SQLite is a public domain embeddable database engine that has many options for .NET language binding.

Answer 6

C#-SQLite is a complete rewrite of SQLite (mentioned by Greg Hewgill) in C#. The Highlight: It's 100% managed .NET code.

Answer 7

If you are using .NET I would go for a MS engine. SQL Express is garanteed to work good with .NET Now dependes on the size of your poject and the load the engine will be handling.-

Hope this helps.-
