[Question] How to do migrations

How do you do migrations in this project?

Based on the clean architecture repo (https://github.com/jasontaylordev/CleanArchitecture) I tried this PS C:\TMP\Blazor\MVP\BlazorClean> dotnet ef migrations add "itemv1" --project src\Infrastructure --startup-project src\Blazor.Server.UI --output-dir Migrators.MSSQL\Migrations

Resulting in error Your target project 'CleanArchitecture.Blazor.Infrastructure' doesn't match your migrations assembly 'CleanArchitecture.Blazor.Migrators.MSSQL'. Either change your target project or change your migrations assembly.

How should the command be for MSSQL?

Geen probleem! 😃

@neozhu, I will update the readme somewhere soon, so it’s more clear on how to create migrations. I had the same issue in the beginning, so if we improve the documentation on how to do so, it should be more clear for new users!

Hey @jochem4207,

There are multiple options you could use.

Option 1 (Command Line)

Try using the following command, and make sure to replace yourMigrationName with the name you want to give the migration, so in your case, probably itemv1.

dotnet ef migrations add --project src/Migrators/Migrators.MSSQL/Migrators.MSSQL.csproj --startup-project src/Blazor.Server.UI/Blazor.Server.UI.csproj --context CleanArchitecture.Blazor.Infrastructure.Persistence.ApplicationDbContext --configuration Debug yourMigrationName --output-dir Migrations

Option 2 (Visual Studio)

However don’t change the settings to PostgreSQL, since this screenshot is on how to create a migration when using PostgreSQL, but you should get a general idea of how to create a migration.

Option 3 (Rider)

1. Install the Entity Framework Core UI plugin.
2. Go to the toolbar and click Tools, then Entity Framework Core, and then Add Migration.

4. Click on OK

I hope this helps, and otherwise, let me know!

Kind regards, Bram (Je landgenoot 😊)
