How to change the output folder for migrations with asp.net Core?

Does anyone know how to change the output directory of the following command?

dotnet ef  migrations add Initial --context EsportshubApi.Models.ApplicationDbContext

I tried to add the option:

--content-root-path 'Migrations/Identity'

But that doesn’t do anything. There is a --data-dir option as well and something else with directory. But none of them is the output for migrations.

My problem is that I have 2 DbContexts so I want their migrations to be separated.

Method 1

dotnet ef migrations add Initial --context EsportshubApi.Models.ApplicationDbContext -o YourFolderPath

dotnet ef migrations add

Adds a new migration.

Arguments:

Options:

Also here are the common options you can use with this command.

Method 2

For Package Manager Console run this command:

PM> Add-Migration 001 -OutputDir "Data/Migrations"

My structure is:

.AspCoreProject
  -Data
    -Migrations
       20190721162938_001.cs
       MainDbContextModelSnapshot.cs

Update:

For removing last migration use:

PM> Remove-Migration

Note: If the migration is already applied to the database, then you will get this error:

The migration ‘20190721162938_001’ has already been applied to the database. Revert it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration.

Then run:

PM> Remove-Migration -Force

If your migration is not the last migration. first, rollback to the migration you need by Update-Database then delete all migration classes after that migration.

PM> Update-Database -Migration 001

This will revert all migrations after 001

Method 3

In EF Core 5.0, you are free to move Migration files and changes their namespace manually. New migrations are created as siblings of the last migration. Alternatively, you can specify the directory at generation time as follows:

.Net core CLI

dotnet ef migrations add InitialCreate --output-dir Your/Directory

PowerShell

Add-Migration InitialCreate -OutputDir YourDirectory

EF Core 5.0 documentation

Method 4

You just need to use -o Or –output option with your command,

To do so, you need to explore to your root project folder, eg: C:projectSampleAPi
and use this command

dotnet ef  migrations add DbInitial --context SampleAPi.Infrastructure.DbContext -o Infrastructure/Migrations

and then

dotnet ef database update
