# MVVM 생성 결과

## 엔티티: {EntityName}

### 생성된 파일
| 파일 | 경로 | 상태 |
|------|------|------|
| Model | /Models/{EntityName}.cs | 생성됨 |
| ViewModel | /ViewModels/{EntityName}ViewModel.cs | 생성됨 |
| View | /Views/{EntityName}View.xaml | 생성됨 |
| Code-Behind | /Views/{EntityName}View.xaml.cs | 생성됨 |
| Messages | /Messages/{EntityName}Messages.cs | 생성됨 |
| Service Interface | /Services/I{EntityName}Service.cs | 생성됨 |

### 다음 단계
1. `I{EntityName}Service` 구현
2. DI 컨테이너에 등록
3. View 내비게이션 추가
4. 필요 시 디자인 타임 데이터 생성
