What is the safest workflow for applying Entity Framework Core schema changes?▼

The safest workflow for applying Entity Framework Core schema changes involves verifying compilation, generating a descriptive migration, applying it to a local database, and running integration tests to validate behavior.

Do I need the dotnet SDK installed to generate EF Core database migrations?▼

Yes, you need the dotnet SDK with EF Core tooling installed, along with access to your project files, to generate and apply database migrations for your .NET application.

Can I apply EF Core migrations to a local or test database for validation?▼

Yes, you can apply EF Core migrations to a local or test database to synchronize the schema and run integration tests, ensuring the model changes behave as expected before deployment.

What should I check before generating an Entity Framework Core code-first migration?▼

Before generating an Entity Framework Core code-first migration, you should check for uncommitted domain model changes and ensure the project compiles successfully to prevent migration errors.

Why does my EF Core migration workflow need a rollback plan?▼

An EF Core migration workflow needs a rollback plan to document potential risks and reversal steps, ensuring that deliberate schema changes can be safely undone if issues arise during deployment.
