title: How to add Extra properties to migration in .net core razor pages without deleting the previous migration or database in EF core
body: <p>I am new in Asp.Net core and making a project Asp.Net core razor pages. So i am using EF core in my project for registration module I wanted to add extra fields of my own as well with the features provided by the EF core.so I created a User Class With additional field. and added the migration from package manager console. And Updated the database .But the problem is when I am adding 1 more property and trying to migrate its giving the error.so what I did is I deleted the migration from the migration folder and deleted the database also and generated the migration with new properties. but certainly this is not a good way of doing it  plz can anyone suggest the proper way without deleting the database.</p>
