Replaced direct service usage in CatalogsController with MediatR-based commands and queries for all CRUD operations. Added command/query and handler classes for Catalog operations. Updated dependency injection to register MediatR and removed ICatalogService. Improved code maintainability and testability by adopting CQRS architecture.
The Update method now checks if CatTitle is being changed and returns a 400 Bad Request if so. It also returns 404 Not Found if the catalog does not exist before attempting an update. This ensures CatTitle remains immutable during updates.
Added a uniqueness check for catalog titles in the creation flow. The service now prevents creating catalogs with duplicate titles by checking for existing entries before insertion. If a duplicate is detected, the API returns a 409 Conflict response. Updated interfaces and repository to support title-based lookups.
Removed Upsert endpoint and related service/repository methods. Deleted ExecuteUpsertAsync helper. Insert now throws NotImplementedException as a placeholder. Refactored Delete method in repository; logic unchanged.
- Split `CatalogDto` into `CatalogReadDto` and `CatalogWriteDto` for clear separation of read/write operations in both backend and frontend.
- Updated API controllers, services, and AutoMapper profiles to use new DTOs; ensured audit fields are set in service layer.
- Enabled CORS in the API project to support Blazor WASM frontend.
- Added new Blazor WebAssembly project (`DbFirst.BlazorWasm`) with catalog management UI, API client, Bootstrap v5.1.0 styling, and configuration-driven API base URL.
- Included `bootstrap.min.css` and its source map for frontend styling and easier debugging.
- Updated solution file to include new project and support multiple build configurations.
- Result: improved API design, clean DTO separation, and a modern interactive frontend for catalog management.
Refactor UpdateWithStoredProcedure to accept id from the route and set dto.Guid accordingly. In the repository, use Guid for existence checks instead of CAT_TITLE, and ensure CatTitle is not changed via the SP. Improve error handling to return NotFound when appropriate.
Added support for updating and deleting Catalog records via SQL Server stored procedures. Introduced PUT /catalogs/sp and DELETE /catalogs/sp/{id} endpoints in CatalogsController. Extended service and repository interfaces and implementations to handle stored procedure operations. Added Microsoft.Data.SqlClient package for direct SQL execution. Repository checks for record existence before SP calls to prevent unintended behavior.
Set up multi-project solution with DbFirst API, Application, Domain, and Infrastructure layers. Implemented database-first EF Core for the Catalog entity, including domain, DTOs, repository, service, and controller. Configured AutoMapper, DI, Swagger, and project settings. Added .gitattributes and initial configuration files.
