The Complete Guide to ASP.NET Core MVC (.NET 5) - Common Error and Delete Product

The video tutorial covers how to properly delete products and their associated images from a database, ensuring that both the product and its image are removed. It also addresses handling edge cases when creating new products, focusing on model state validation and error handling. The tutorial demonstrates how to manage model state and view rendering, ensuring that necessary data is populated to prevent errors during product updates.

What is the first step to ensure that an image file is removed when deleting a product?

• Open the images folder to verify deletion

• Add a debugger to the application

• Check if the file exists and then remove it

• Remove the product from the database first

What common error might students face when creating a new product without client-side validation?

• The model state is invalid due to missing required properties

• The application crashes without any error message

• The product is created without an image

• The model state is valid but the product is not saved

What should be done if the model state is invalid to prevent the view from encountering null values?

• Remove all validation scripts

• Ignore the invalid model state

• Add an else block to load necessary data

• Stop the application immediately

How can you ensure that errors are handled correctly when creating a product?

• Ignore errors and proceed with product creation

• Only validate on the server side

• Enable client-side validation and check the model state

• Disable all validation scripts
