Logic is an exact port of the old `AuthService.LoginAsync` body (trim username, look up user by username with role, verify password, check `IsActive`, throw `UnauthorizedException`/`ForbiddenException` as before, build `LoginResponse` with token + mapped `UserDto`). + +3. **Deleted `mws.application/Auth/AuthService.cs`** — removed the old file containing both `IAuthService` and `AuthService`, now fully superseded by `LoginCommand`/`LoginHandler`. + +4. **Replaced `mws.api/Controllers/AuthController.cs`** — controller now depends on `ISender` instead of `IAuthService`; `Login` action sends `new LoginCommand(request)` via `sender.Send(...)` and returns `Ok(response)`. Matches the brief's Step 4 exactly. + +5. **Updated `mws.infrastructure/DependencyInjection.cs`**: + - Added `services.AddMediatR(cfg => cfg.RegisterServicesFromAssembly(typeof(IUnitOfWork).Assembly));` immediately after `services.AddAutoMapper(...)`. + - Removed `services.AddScoped();`. + - Left `using Mws.Application.Auth;` in place (still required for `JwtOptions`/`ITokenService` wiring elsewhere in the file), per the brief's explicit instruction. + +## Build output (tail) + +``` +mws.domain -> .../mws.domain/bin/Debug/net10.0/mws.domain.dll +mws.application -> .../mws.application/bin/Debug/net10.0/mws.application.dll +mws.infrastructure -> .../mws.infrastructure/bin/Debug/net10.0/mws.infrastructure.dll +/Users/namdh/Desktop/mws.backend.dotnet/.claude/worktrees/cqrs-mediator/mws.api/Program.cs(69,80): warning CS8604: Possible null reference argument for parameter 's' in 'byte[] Encoding.GetBytes(string s)'.
