Hello! So in the previous video, you removed multi-select to use enums and you've carried on using single-select. In the video that you covered multi-select, you didn't cover how to send that new data to the database- the database was still receiving the singular string value. Would you be happy to cover that?

SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint The conflict occurred in database "BookStore", table "dbo.Language", column 'LanguageId'. The statement has been terminated.

Is it fine to Change Model Randomly also instead of using multiple model for different Operation Can we use ViewModel. Its very informative but implementation is bit Complicated.
