Milestone 1: .NET Foundations & Internals

🟦 Milestone 1: .NET Foundations & Internals

Master the inner workings of the .NET CLR, memory management, and high-performance concurrency patterns by learning the Mechanics before the Abstractions.

🧠 Memory & Performance (The Metal)

• The Mechanic: Manual Memory & Pointers: Unsafe code, stackalloc, and pinning.
• The Abstraction: Span & Memory: Zero-allocation high-performance safety.
• The Engine: Memory Management & GC: How the Garbage Collector works under the hood.

🏗️ Objects & Dependencies

• The Mechanic: Pure DI & Service Location: Understanding DI without a container.
• The Abstraction: Microsoft.Extensions.DI: Standardizing dependency management.

🧵 Concurrency & Parallelism

• The Mechanic: Threads & Synchronization: Working with the raw OS primitives.
• The Abstraction: Task Parallel Library (TPL): Asynchronous programming with async/await.
• The Pattern: Channels: High-performance producer/consumer workflows.

🔍 Inspection & Generation

• Reflection: Inspecting code at runtime (The Mechanic).
• Source Generators: Generating code at compile-time (The Abstraction).

Professor’s Note

“If you cannot explain how memory is laid out on the stack, you cannot optimize a high-traffic ASP.NET Core application. Abstractions are for productivity; understanding is for performance.”
