3. What is the difference between convention-based routing and attribute-based routing in ASP.NET Core?
- There is no difference between them.

- Convention-based routing is used for routing in MVC applications, while attribute-based routing is used for routing in Web API applications.
4. Which of the following is a valid example of using ViewData in ASP.NET Core?

5. What is the main difference between strongly typed and weakly typed forms in ASP.NET Core?
- Strongly typed forms use a model to define the form fields and their data types, while weakly typed forms do not use a model and rely on HTML helpers to generate form fields.
- Strongly typed forms can only be used with Razor syntax, while weakly typed forms can be used with any syntax.
- Strongly typed forms are only supported in the latest version of ASP.NET Core, while weakly typed forms are supported in all versions.
- Strongly typed forms are faster and more efficient than weakly typed forms, but are harder to implement.
6. What is model binding in ASP.NET Core?
- A technique for automatically mapping HTTP request data to action method parameters or model properties.
- A way to enforce strong typing in your HTML form fields.
- A method of client-side validation using JavaScript.
- A way to define the layout and structure of your Razor views.
7. How can you handle a form post in ASP.NET Core?
- By creating an action method in your controller that accepts the form data as parameters.
- By creating a separate class to handle the form post and using dependency injection to inject it into your controller.
- By using a middleware component to intercept the form data before it reaches your controller.
- By creating a custom HTML helper to handle the form post and generate the necessary HTML and JavaScript.
8. What is client-side validation in ASP.NET Core?
- A technique for validating user input on the client using JavaScript.
- A technique for validating user input on the server before processing it.
- A method for storing user input in a database for later retrieval.
- A technique for encrypting user input to prevent it from being intercepted during transmission.
