# MyNewProjectName - Clean Architecture Template

A Clean Architecture template for .NET 9 applications.

## 📁 Project Structure

```
├── MyNewProjectName.Domain          # Enterprise Business Rules (Entities, Value Objects, Domain Events)
├── MyNewProjectName.Application     # Application Business Rules (Use Cases, CQRS, Validators)
├── MyNewProjectName.Contracts       # DTOs for external communication (Requests, Responses)
├── MyNewProjectName.Infrastructure  # External concerns (Database, Identity, Services)
├── MyNewProjectName.WebAPI          # Web API presentation layer
├── MyNewProjectName.AdminAPI        # Admin API presentation layer
└── MyNewProjectName.UnitTest        # Unit tests
```

## 🏗️ Architecture

This template follows **Clean Architecture** principles:

```
┌─────────────────────────────────────────────────────────┐
│  Presentation Layer (WebAPI, AdminAPI)                  │
├─────────────────────────────────────────────────────────┤
│  Infrastructure Layer (EF Core, Identity, Services)     │
├─────────────────────────────────────────────────────────┤
│  Application Layer (MediatR, AutoMapper, Validators)    │
├─────────────────────────────────────────────────────────┤
│  Domain Layer (Entities, ValueObjects, Interfaces)      │
└─────────────────────────────────────────────────────────┘
```

### Dependency Rule
- Inner layers know nothing about outer layers
- Dependencies point inward

## 🚀 Getting Started

### Prerequisites
- .NET 9 SDK
- SQL Server (or modify connection string for other databases)

### Setup

1. **Clone and rename the template**
   ```bash
   # Clone the repository
   git clone <repository-url> MyNewProject
   cd MyNewProject
   
   # Run the rename script
   ./rename-project.sh MyNewProject
   ```

2. **Update connection string**
   
   Edit `appsettings.json` in WebAPI/AdminAPI projects:
   ```json
   {
     "ConnectionStrings": {
       "DefaultConnection": "Your-Connection-String"
     }
   }
   ```

3. **Run migrations**
   ```bash
   cd MyNewProjectName.Infrastructure
   dotnet ef migrations add InitialCreate --startup-project ../MyNewProjectName.WebAPI
   dotnet ef database update --startup-project ../MyNewProjectName.WebAPI
   ```

4. **Run the application**
   ```bash
   dotnet run --project MyNewProjectName.WebAPI
   ```

##  NuGet Packages

### Application Layer
- **MediatR** - CQRS pattern implementation
- **AutoMapper** - Object-to-object mapping
- **FluentValidation** - Validation rules

### Infrastructure Layer
- **Entity Framework Core** - ORM
- **Microsoft.AspNetCore.Identity** - Authentication/Authorization

## 🔧 Key Features

-   Clean Architecture structure
-   CQRS with MediatR
-   Validation pipeline with FluentValidation
-   Logging pipeline behavior
-   Global exception handling
-   Generic Repository pattern
-   Unit of Work pattern
-   AutoMapper integration
-   Multi-API support (WebAPI + AdminAPI)
-   Auditable entities
-   Soft delete support
-   Domain events support

## 📝 Usage Examples

### Creating a new Feature

1. **Add Entity** in `Domain/Entities/`
2. **Add Repository Interface** in `Domain/Interfaces/`
3. **Add Command/Query** in `Application/Features/{FeatureName}/`
4. **Add DTO** in `Contracts/DTOs/`
5. **Add Controller** in `WebAPI/Controllers/`

### Sample CQRS Structure

```
Application/Features/Sample/
├── Commands/
│   └── CreateSample/
│       ├── CreateSampleCommand.cs
│       ├── CreateSampleCommandHandler.cs
│       └── CreateSampleCommandValidator.cs
└── Queries/
    └── GetSamples/
        ├── GetSamplesQuery.cs
        ├── GetSamplesQueryHandler.cs
        └── SampleDto.cs
```
