说明
dotnet ef is the Entity Framework Core CLI tools for database migrations and scaffolding. It enables code-first database development and reverse engineering from existing databases. The migrations system tracks schema changes in code, generating incremental updates that can be applied to databases. Each migration is a class describing schema modifications. dbcontext scaffold reverse-engineers a DbContext and entity classes from an existing database, useful for database-first development or migrating legacy databases.
