Answer 1

Hi,

I hope you are talking about code first approach

once you create database using code first approach then after that if you want to change the model class . that reflect your database

if you do not want loose any column value then use migration

here is step

open your package manager console type the following comand

1. enable-migrations

2. add-migration

3. update-database

when ever you change the model class repeat the second and third step
