C# Mastery Journey

This repository documents my progress mastering modern C# (v12/14) and .NET (v8/10) through daily coding challenges.

Focus Areas

• Modern Syntax: Records, Pattern Matching, Collection Expressions, Primary Constructors.
• Performance: Span<T>, Memory<T>, ValueTask<T>, Zero-Allocation parsing.
• Architecture: Domain-Driven Design (DDD), Result Pattern, Dependency Injection.
• Domain: Enterprise Asset Management (EAM) & Industrial IoT (Pumps, Telemetry, Sensors).

Progress

• Week 1: Modern C# Refresh (Records, Pattern Matching)
• Week 2: Advanced Initialization & Null Safety
• Week 3: Intermediate .NET (Async/Await, Generics, Streaming)
• Week 4: Intermediate .NET Deep Dive (Expression Trees & Advanced Memory)

How to Run

Requires .NET 8.0 SDK or later.

cd W01/Day03/
dotnet run

CLI Helper

Use the interactive script to create a new day project or run an existing one:

bash scripts/csharp-journey.sh

When creating a project, the script asks whether to place it in the last week or create a new week, then picks the next available DayXX folder automatically.
