I have a project (.NET 3.0, c#) that needs to be converted to open source (probably GPLv2).

The project uses some closed source libraries at its core that need to be replaced with open source ones.

Can anyone point me in the direction of the best open source replacements for the following libraries?

Thanks!

VistaDB can be replaced by MySQL, SQLite, or even the express version of SQL Server 2008 (although SQL Server is not GPL).

Indeed, for an open source project you would normally try to allow any reasonably modern database backend, rather than tie to a single embedded engine.

There's a simple SMTP client built into .Net.
