Base class for code-based migrations.

Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc.

Explicit Interface Implementations

IDbMigration.AddOperation(MigrationOperation)

Adds a custom MigrationOperation to the migration. Custom operation implementors are encouraged to create extension methods on IDbMigration that provide a fluent-style API for adding new operations.
