How to update models and DBContext class in Entity Framework core (if database created first)

Question

As the title indicates I Have an SQL server database already made and I excuted the following command to generate DBContext class and the model:

Scaffold-DbContext "connectionstring" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

later on a table has been added through SQL server( Not through a model migration command)

is there a way to generate the related model for it and update the dbContext ?

if i re-excute the command above I would get Build Failed

Hi @Angular Dev, I think you need first check the `Error List` if any error in your project. Build Failed is because your project contains any error. — Rena, Jun 02 '22 at 02:24

Use

-Force

Or have a look at EF Core Power Tools.
