💡 Key Difference: IServiceScopeFactory is always a singleton, but IServiceProvider follows the lifetime of the class it’s injected into.
| Feature | IServiceProvider | IServiceScopeFactory |
|---|---|---|
| Purpose | Resolves dependencies | Creates a new scope for resolving dependencies |
| Creates New Scope? | ❌ No (not its primary purpose) | ✅ Yes (optimized for scope creation) |
| Lifetime | ❌ Depends on containing class | ✅ Always Singleton |
| Usage | Used in constructors and methods to get dependencies | Used in background services & singletons to get scoped dependencies |
| Scoped Service Resolution | ❌ Not safe in singletons | ✅ Safe, as it creates a scope |
