What are the differences between ASP.NET routing attributes and conventional routing?

ASP.NET routing attributes allow you to define routes directly on your controller actions, making it more intuitive. Conventional routing, on the other hand, relies on a predefined route template and is set up in the route configuration.

Can you give me an example of each?

Sure! For attribute routing, you might use [Route("api/[controller]")] above your action method. For conventional routing, you would define a route like `routes.MapRoute(name: "Default", template: "{controller=Home}/{action=Index}/{id?}"); in the Startup.cs.

Which one is better for a large application?

For large applications, attribute routing can be more manageable as it keeps routes close to the action methods, making it easier to understand and maintain. However, conventional routing can be beneficial for simpler applications or when you want a consistent routing structure.

Are there any performance differences between the two?

Generally, the performance difference is negligible. However, attribute routing may introduce a slight overhead due to the additional metadata processing. In most cases, the choice should be based on maintainability rather than performance.
