Fixing Unity ANR Errors: The Masterclass on Async/Await in C#

Описание: Unity ANR Fix: Mastering C# Async/Await | Engineering Case Study #1

Application Not Responding (ANR) errors are the silent killer of user retention and ASO rankings. In this engineering case study, we deep-dive into why the Unity Main Thread freezes and how to refactor blocking synchronous code into a high-performance, asynchronous architecture.

As a developer with 15+ years of experience, I’ve seen how "callback hell" and poorly managed threads can ruin a production app. Today, we’re moving past basic tutorials to look at production-grade C# patterns.

🛠 What We’re Covering:
The Anatomy of an ANR: Why I/O, API calls, and heavy disk writes hijack your UI.

Tasks vs. Promises: Bridging the gap for JavaScript developers moving to C#.

The Unity Threading Trap: Solving the "get_isActiveAndEnabled can only be called from the main thread" exception.

Scaling with Task.WhenAll: How to fire parallel requests without breaking your app.

Async File I/O: Modernizing Save/Load managers with StreamWriter.WriteAsync.

🏗 The "Building in Public" Journey:
I am currently applying these exact patterns to my upcoming Crypto Market AI Intelligence Tool (Launching Feb 2026). Handling real-time market data requires a non-blocking architecture at scale.
