Reflection and Expression Trees in .NET for Custom ORM Development

Writing adaptable and high-performance .NET applications often requires working directly with code metadata and dynamic execution. Understanding Reflection and Expression Trees unlocks the ability to inspect types at runtime and generate optimized code on the fly. In this course, you will progress from core runtime concepts to building a working micro-ORM library. You will discover how reflection works under the hood, learn to construct expression trees that compile into fast delegates, and apply these techniques to eliminate redundant data-mapping code. What you'll learn: - Understand foundational concepts of .NET metadata, reflection, and dynamic execution. - Inspect types, attributes, and members at runtime using standard reflection APIs. - Construct complex expression trees and compile them into strongly-typed delegates for high performance. - Apply dynamic code generation techniques to map database records to objects efficiently. - Explore modern source generator concepts and dynamic compilation considerations. - Practice building a lightweight micro-ORM through step-by-step written guides and code exercises. The course begins with essential terminology, runtime type inspection, and metadata concepts before advancing to dynamic expression trees and delegate compilation. Through detailed text explanations and code snippets, you will incrementally develop a functional data access library. This course is designed for developers looking to master dynamic metaprogramming and internal runtime capabilities.
