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.

A number of tutorials are available from http://www.rikware.com/RikMigrations.html and more are being added regularly. Please be patient as the documentation is created. Development is being supported by my job, but documentation is not :s
If you have specific questions drop a comment here or contact me via the contact page at http://www.rikware.com/contact.aspx. I will concentrate documentation efforts around people's requests.
