I’m new to ASP.NET Core and learning. I’ve been trying for few days now trying to implement a simple form in ASP.NET Core 8 with multi-select drop-down list.

I’m not sure why implementing multi-select drop-down list is so difficult in asp.net core. I want to use X.PagedList on the Index page. This form will have nothing but two fields – Firstname a text field and a multi select drop-down list that contains three options – A, B and C. I need to be able to do CRUD options including Index page that will list all the forms entries stored in a database.

Can someone provide a simple but complete example or point me to an existing solution that I can download?
