You can represent related settings using classes, which gives you strong typing for those settings.

✨ Benefits:
By applying this pattern, your app follows two important software engineering principles:

🔒 𝐄𝐧𝐜𝐚𝐩𝐬𝐮𝐥𝐚𝐭𝐢𝐨𝐧 – services only depend on the settings they actually use.
🧩 𝐒𝐞𝐩𝐚𝐫𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐜𝐨𝐧𝐜𝐞𝐫𝐧𝐬 – configuration logic is separated from business logic.

𝐈𝐎𝐩𝐭𝐢𝐨𝐧𝐬
• Reads configuration once at startup.
• ❌ Doesn’t update if config changes while the app is running.
• 🟢 Registered as Singleton, can be injected anywhere.

𝐈𝐎𝐩𝐭𝐢𝐨𝐧𝐬𝐒𝐧𝐚𝐩𝐬𝐡𝐨𝐭
• Reads configuration fresh on every request.
• Useful for per-request updates (e.g., in web apps).
• 🟡 Registered as Scoped, so cannot be injected into Singletons.

𝐈𝐎𝐩𝐭𝐢𝐨𝐧𝐬𝐌𝐨𝐧𝐢𝐭𝐨𝐫
• Supports real-time updates without restarting the app.
• Can trigger callbacks when config changes.
• 🟢 Registered as Singleton, safe to inject anywhere.

💡** Quick Summary**
• IOptions → Static, simple, app startup only.
• IOptionsSnapshot → Per-request updates.
• IOptionsMonitor → Real-time updates with change notifications.
