ASP.NET Core Best Practices - Web

Introduction

This page provides a high-level overview of key best practices for building robust and scalable ASP.NET Core web applications.

We'll cover areas like architecture, code organization, testing, deployment, and monitoring.

Architecture & Design

Favor a layered architecture: Presentation, Business Logic, and Data Access layers. Use Dependency Injection for easier testing and maintainability.

Microservices for large, complex apps - separate concerns and technologies.

Code Organization & Structure

Use PSR-0 or similar standards. Implement clear naming conventions. Document your code thoroughly. Follow DRY (Don't Repeat Yourself) principles.

Feature-based development – organize code around features rather than functions.

Testing & Quality Assurance

Unit Tests - test individual components.

Integration Tests - test the interaction between components.

End-to-End Tests - test the entire application.

Code Coverage - measure how much of your code is covered by tests.

Deployment & Infrastructure

Use Azure DevOps or similar for CI/CD (Continuous Integration/Continuous Deployment).

Utilize .NET Core Dev Containers - containerized development environment.

Infrastructure as Code - automate infrastructure setup.

Monitoring & Logging

Centralized logging with Serilog or NLog. Monitor key metrics (CPU, memory, response time).

Use Application Insights for detailed insights.

Additional Considerations

Use a SOLID principle foundation for design.
