## GitHub Copilot AI Rules for .NET Development Best Practices

### Rule 1: Code Structure
- **Enforce Layered Architecture**: Ensure all projects follow a clear separation of concerns with distinct layers (Presentation, Business Logic, Data Access).
- **Use Dependency Injection**: All dependencies should be injected via constructor injection.

### Rule 2: Naming Conventions
- **Class Names**: Use PascalCase for class names (e.g., `CustomerService`).
- **Method Names**: Use PascalCase for method names (e.g., `GetCustomerDetails`).

### Rule 3: Performance Optimization
- **Avoid N+1 Queries**: Use eager loading or include related data in a single query.
- **Use Async/Await**: Ensure all I/O operations are asynchronous.

### Rule 4: Error Handling
- **Use Custom Exceptions**: Create specific exceptions for business logic errors.
- **Log Errors**: All exceptions should be logged with relevant context.

### Rule 5: Security
- **Input Validation**: Validate all inputs at the controller level.
- **Use Parameterized Queries**: Avoid SQL injection by using parameterized queries.
