metadata	{"author":"Altinn"}

Add a new migration

dotnet ef migrations add <MigrationName> \
  --project src/WorkflowEngine.Data \
  --startup-project tests/WorkflowEngine.TestApp

After generating, run dotnet csharpier format on the new migration files in src/WorkflowEngine.Data/Migrations/.

List existing migrations

dotnet ef migrations list \
  --project src/WorkflowEngine.Data \
  --startup-project tests/WorkflowEngine.TestApp

Remove the last migration (if not yet applied)

dotnet ef migrations remove \
  --project src/WorkflowEngine.Data \
  --startup-project tests/WorkflowEngine.TestApp

Important notes

• Migrations are applied automatically on application startup via DbMigrationService — there is no need to run dotnet ef database update manually.
• Migration files live in src/WorkflowEngine.Data/Migrations/.
• The DbContext is EngineDbContext in WorkflowEngine.Data.
• Always format generated migration files with CSharpier before committing.
