Using Options pattern (IOptions<T>, IOptionsSnapshot<T>,?

IOptionsMonitor<T>)

• IOptions<T>: Reads settings once at startup.
• IOptionsSnapshot<T>: Gets updated settings per request (for scoped services).
• IOptionsMonitor<T>: Supports change notifications and works in singleton

services.

public MyService(IOptions<MySettings> options) {
var settings = options.Value;
}
