Hi,
I am trying to populate a database with three fields. UserIf, registration date, and last login date. Seems easy enough so I followed a couple of tutorials that told me to create the database table and the columns before adding a new class to my IdentityModels.cs
files in my web forms app. Then they say I must enable migrations for it to work because when I try to create a new users I get an error saying "The model backing the 'ApplicationDbContext' context has changed since the database was created. Consider using
Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269)."
I followed the instructions to enable migrations in Nuget console. Problem is whenever I go to my Nuget console in VS 2019 it says that Enable-Migrations or enable-migrations is an invalid parameter:
Each package is licensed to you by its owner. NuGet is not responsible for, nor does it grant any licenses to, third-party packages. Some packages may include dependencies which are governed by additional licenses. Follow the package source (feed) URL to

Can this be solved faster than just adding SQL to the code behind on my registration and login pages?
