SqlTools is a .NET 2.0 library that wraps Mysql and SqlServer api's. This tool allows one to communicate with those two databases much more easily. The code you use won't require a complete rewrite when changing between those two databases.
This tool also decreases the repetitious code designs necessary to build applications and websites with database backends and leaves you with plenty of time to focus on what is important: building a successful project that just happens to rely on the database.
