What I Do

I help you create production-ready ASP.NET Core Web API projects with:

• Clean architecture structure
• Proper dependency injection
• Swagger/OpenAPI documentation
• Global exception handling
• Request/response logging
• API versioning
• Health checks
• CORS configuration

When to Use Me

Use this skill when:

• Creating a new Web API project
• Setting up API infrastructure
• Adding middleware and filters
• Configuring API best practices

What I Create

Project Structure:

src/{ProjectName}.Api/
├── Controllers/
├── Filters/
│   ├── GlobalExceptionFilter.cs
│   ├── ValidationFilter.cs
│   └── ApiKeyFilter.cs
├── Middleware/
│   ├── RequestLoggingMiddleware.cs
│   └── ErrorHandlingMiddleware.cs
├── Extensions/
│   ├── ServiceCollectionExtensions.cs
│   └── ApplicationBuilderExtensions.cs
├── Models/
│   └── ErrorResponse.cs
├── Program.cs
└── appsettings.json

Key Features:

• Program.cs configured with:

  • Controllers and minimal APIs
  • Swagger/OpenAPI
  • Health checks
  • CORS
  • Global exception handling
  • Request validation
  • API versioning

• GlobalExceptionFilter.cs handles exceptions

• ValidationFilter.cs validates requests

• RequestLoggingMiddleware.cs logs requests/responses

Best Practices I Follow

1. Use minimal APIs for simple endpoints
2. Implement proper HTTP status codes
3. Validate all inputs
4. Use DTOs for API models
5. Implement proper error responses
6. Add XML comments for Swagger
7. Configure health checks
8. Use API versioning from start

Example Usage

Create a new ASP.NET Core Web API project with:
- Swagger/OpenAPI documentation
- Health checks endpoint
- Global exception handling
- Request validation
- API versioning
- CORS configuration

I will generate all necessary files following .NET 8 best practices.
