Syllabus

Getting Up and Running with Minimal API Development

In this section, we explore minimal APIs using .NET 9.0 SDK, focusing on efficient setup, reduced overhead, and practical benefits over traditional approaches.

Creating Your First Minimal API

In this section, we explore building minimal APIs in .NET, focusing on project structure, defining HTTP endpoints, and handling requests and responses effectively.

The Anatomy of a Minimal API

In this section, we explore the structure of minimal APIs in ASP.NET, focusing on components like routing, middleware, and the request lifecycle to enhance application design and performance.

Handling HTTP Methods and Routing

In this section, we explore configuring HTTP endpoints, managing route parameters, and implementing request validation and error handling in minimal APIs for reliable API interactions.

The Middleware Pipeline

In this section, we explore ASP.NET middleware pipelines, focusing on configuring order, implementing custom middleware, and optimizing performance for scalable API development.

Parameter Binding

In this section, we explore parameter binding in API requests, focusing on sources like route values, query strings, and headers, and how to map client data to server-side objects for effective API interactions.

Dependency Injection in Minimal APIs

In this section, we will learn DI in ASP.NET, including container configuration, service lifetimes, and best practices for scalable development.

Integrating Minimal APIs with Data Sources

In this section, we will learn integrating minimal APIs with SQL and NoSQL databases for persistent data storage and management.

Object Relational Mapping with Entity Framework Core and Dapper

In this section, we explore how to use Object Relational Mapping (ORM) frameworks—specifically Entity Framework Core and Dapper—to configure minimal API projects and perform CRUD operations while promoting scalable and maintainable database interactions.

Profiling and Identifying Bottlenecks

In this section, we explore profiling techniques, resource monitoring, and common bottlenecks to optimize API performance and improve system efficiency.

Utilizing Asynchronous Programming for Scalability

In this section, we explore asynchronous programming in minimal APIs, focusing on non-blocking task execution, scalability, and common challenges like deadlocks and race conditions.

Caching Strategies for Enhanced Performance

In this section, we explore caching strategies to reduce system strain, including in-memory, distributed, and response caching techniques for improved API performance and resource efficiency.

Best Practices for Minimal API Resiliency

In this section, we explore code organization, error handling, and security practices to enhance API readability, scalability, and resilience using structured design patterns and best security protocols.

Unit Testing, Compatibility, and Deployment of Minimal APIs
