This repository is a central hub for all the advanced .NET and ASP.NET Core features I introduce on LinkedIn. It provides hands-on implementations of key concepts with real-world examples, allowing you to explore, test, and integrate them into your projects.

• ✅ Feature Management & Feature Flags
• ✅ Rabbitmq Eventbus Ready for Miroservices
• ✅ Aspire Orchestration
• ✅ Aspire App Host Integration Tests
• ✅ IdempotentFusion (Idempotent Api with optional lock)
• ✅ Reusable Generic Cursor Pagination
• ✅ Manual Mediator with Pipeline Behavior
• ✅ Api Versioning Strategies
• ✅ Generic and Reusable Api Validations
• ✅ Middleware Dynamic Caching
• ✅ App Initializer
• ✅ High-Performance Caching (Memcached, Redis, etc.)
• ✅ Distributed Rate Limiting with YARP & Memcached
• ✅ Advanced API Design & Middleware
• ✅ Optimized Data Processing Techniques
• ✅ Performance Improvements & Best Practices
• 🧩 Design Patterns

Each feature is structured for easy exploration and practical implementation.
Functional Tests need Docker installed and running.

This example demonstrates distributed rate limiting using YARP (Yet Another Reverse Proxy) and Memcached. This approach ensures that API rate limits are enforced consistently across distributed instances.

or

Run the following command to spin up Memcached:

docker-compose up -d

The YARP reverse proxy is configured to limit incoming requests based on IP-based quotas stored in Memcached.

• 100 requests per minute per IP
• Requests exceeding the limit receive a 429 Too Many Requests response

Use a tool like Postman or cURL to send multiple requests:

curl -X GET http://localhost:5000/api/resource -H "Authorization: Bearer <your_token>"

Once the limit is reached, you’ll receive:

{
  "error": "Too Many Requests"
}

This example demonstrates feature management in ASP.NET Core using feature filters. Feature filters allow conditional feature toggling based on factors like user claims, enabling personalized experiences.

or

To enable the Memcached-based feature toggle, run:

docker-compose up -d

To test VIP-based feature toggling, generate a JWT token using the following credentials:

• Username: vipuser
• Password: vippassword

Once you have the JWT token, call the API:

GET /custom-greeting
Authorization: Bearer <your_jwt_token_here>

This section contains various design patterns implemented in .NET, showcasing real-world use cases and best practices. Some of the patterns you'll find include:

• Mediator Pattern
• Adapter Pattern
• Decorator Pattern
• Singleton Pattern
• Factory Pattern
• Repository Pattern
• Strategy Pattern
• CoR Pattern
• Observer Pattern
• Dependency Injection

Each pattern is demonstrated with clear code examples and explanations of when and why to use them.
