Server and Client Side Data Validation in ASP MVC Core and Learn to create custom attribute

We will use Data Annotation to implement validation. Below are the data annotation we are going to use in this video

Required - To be put on mandatory fields so that user should not be able to submit blank values in those fields
Range - To validate the range i.e. year should be between 2000 to current date
EmialAddress - Validate email address
RegularExpression - If anything that can not be validated using available data annotations / Attributes we can use regular expression

We need to use above data annotation on our Model class and it will work for both Server side and client side validation

We will use tag helper named "asp-validation-for" to display the error message to user

And for client side validation we need to add following libraries to our project

1. jquery
2. jquery-validation
3. jquery-validation-unobtrusive
