.NET Core with jquery.validate.unobtrusive: error messages are missing

I am using jquery.validate.unobtrusive with .NET Core to do client-side validation. I see the form validation is working (upon error the input is turning red …) but I do not see the error messages. I think error messages should be visible, at least that’s I have seen sofar link1 link2

I have already done:

1. import scripts for jquery.validate.js and jquery.validate.unobtrusive.js
2. ClientValidationEnabled = true
3. Added System.ComponentModel.DataAnnotations validation attributes

I cannot post the whole code so this the repository

Method 1

You can also use ValidationSummary on top like below:

@Html.ValidationSummary()
<!-- your fields here -->

Method 2

I was missing the following in razer:

@Html.ValidationMessageFor(m => m.Username)
