Validation Tag Helpers in ASP.NET Core
The ASP.NET provides validation related tag helpers which display the validation messages to the user. We learned how server-side model validation works in the previous tutorial. The Model binder binds and validates the data received over the HTTP Request. It then creates the ModelState object, which contains the validation messages generated by the Model Binder. The Validation Tag helpers generate the HTML element to display these messages in the view.
