Model Binding Masterclass: Mastering Request Sources
1. [FromQuery] (The Search & Filter Source)
Typically used for pagination, filtering, and optional parameters. /Products?id=123. Values are optional.
2. [FromRoute] (The Immutable Resource Source)
Used to identify a specific record in a RESTful manner. /Products/123/Details. If the route parameter is missing, the request fails (404).
