One extremely handy open source library for .NET developers is FluentMigrator. This package allows you to script out your database changes as C# classes. The concept is similar to the code first migrations of EntityFramework, but allows you a bit more fine tuned control over deployments and doesn’t tie you to any specific ORM or other database interaction model. For example, it’s easy to control which environments the updates go to with tagging. This can help prevent accidental database updates to production and has already saved me from database restores on a couple of occasions.
