Master Web API Development in C# with ASP.NET Core: Build Scalable, Secure, and AI-Enhanced APIs for the Future

Unlock the power of APIs and boost your C# development skills with our comprehensive Web API Development in C# course. Learn how to build high-performing, scalable APIs using ASP.NET Core—an essential framework for modern application development. Whether you're developing mobile apps, IoT solutions, AI-driven features, or connecting multiple software systems, mastering Web API development will make you an invaluable asset in today’s IT landscape. This course is tailored for developers familiar with .NET and C# who are ready to take their skills to the next level by exploring the world of API development.

Course Highlights

• Hands-On Experience: Gain practical knowledge by building RESTful APIs from scratch and integrating real-world AI services such as chatbots, sentiment analysis, and image recognition.
• Cross-Platform Compatibility: Learn how ASP.NET Core enables you to develop APIs that work across various platforms (like Linux and Windows), run on any public cloud (like Azure, AWS, or Google Cloud), and support AI features from established providers like Azure AI and OpenAI.
• Comprehensive API Design: Master the fundamental principles of API design, including handling JSON data structures, asynchronous operations, and input validation tailored for both traditional and AI-powered APIs.
• Advanced Topics: Explore API security, input validation, versioning, AI-enhanced testing, responsible AI practices, and automated documentation using Swagger/OpenAPI.

What You Will Learn

• Understand and explain the core principles of API design.
• Set up and configure a complete ASP.NET Core development environment using Visual Studio for API development.
• Design and develop scalable RESTful APIs using ASP.NET Core, with full control over routing, controllers, and middleware.
• Ensure your APIs are secure, maintainable, and up-to-date by implementing industry-standard practices in API security, versioning, and documentation.
• Serialize and deserialize data from machine learning models and ensure reliable communication through input validation, retry policies, and rate limiting strategies.
• Use AI tools for generating automated test cases and analyzing API logs for intelligent monitoring and diagnostics.

Course Topics

• Designing RESTful APIs: Best practices for structuring your APIs for scalability and ease of use.
• Implementing REST APIs: Learn how to retrieve, create, update, and delete resources using ASP.NET Core.
• Input Validation: Build robust APIs by validating incoming requests to ensure data integrity.
• Securing Web APIs: Implement essential security features to protect your APIs from unauthorized access.
• API Documentation and Versioning: Learn how to document your APIs with Swagger/OpenAPI and manage versioning for future-proof development.
• JSON Handling and Serialization: Work with structured JSON data returned by AI APIs, and handle complex serialization/deserialization when consuming or exposing ML models.
• Performance and Reliability: Apply async programming, batching, and smart caching to improve responsiveness, particularly for AI requests that may have longer processing times.
• Testing and Monitoring: Use AI-powered tools to auto-generate test cases, analyze logs for unusual activity, and enhance observability across your API ecosystem.
• Responsible AI Practices: Learn how to identify and address bias in AI models exposed via your APIs, ensure compliance with data privacy regulations (like GDPR), and protect your system from AI abuse and overuse.
