Model Validation in ASP.NET Core MVC
In this tutorial, we look at how ASP.NET core Model Validation works. Often the data entered by the user is not valid and cannot be saved into the database. The entered data may contain a typo or user may intentionally enter the inappropriate data. Hence, we need to validate the user input before storing it in the database. The ASP.NET Core gives us Model Validator, which uses the validation attributes to validate the model, which makes our task easier. We also take a look at ModelState and how to use it. Finally, we look at the list of Validation attributes.
