Entity Framework - Migrations in SQL Server Database

Code Based Migration. When you develop a new application, your data model changes frequently, and each time the model changes, it gets out of sync with the database. You have configured the Entity Framework to automatically drop and re-create the database each time you change the data model.

By mistake Instead of typing add-migration "addedCourse" I typed update-database "addedCourse" and then got "build failed"... what is the issue?

I got this message: "Enable-Migrations is obsolete. Use Add-Migration to start using Migrations."

[gitbunde]

No context type was found in the assembly 'IanEvents'

[miauw]

3 Steps to do:
o Enable-Migrations (only do this step once)
o Add-Migration "name of migration"
o Update-Database


--> Next migration
o Add-Migration "name of migration"
o Update-Database

Very basic, was expecting something more. Probably the EF-hell problems
