RikMigrations is a database migration library for .NET based on the migrations facility provided by Ruby on Rails. It allows simple upgrading and downgrading of databases using .NET code (such as VB or C#) either from the command line or built into your application. Unlike many other migration frameworks, RikMigrations is a stand-alone library which does not rely on a large surrounding framework.
