A VS Code extension to manage Entity Framework migrations.

• dotnet sdk
• efcore tools
• Microsoft.EntityFrameworkCore.Design must be installed in one of the projects

• List migrations by DbContext
• Add / Remove / Run / Undo migrations
• Show migration applied status
• Reset (Squash) Migrations
• Export DbContext as SQL script
• View DbContext information
• Scaffold DbContext & entity types
• Generate ER Diagram (Requires EF Core 7+)

Set the project and startupProject configuration for the workspace by clicking on the Configure icon in the tree view:

This extension contributes the following settings:

• entityframework.project: Target Project

  Example

  {
    "entityframework.project": "src/Infrastructure"
  }

• entityframework.startupProject: Startup Project

  Example

  {
    "entityframework.startupProject": "ExampleAPI"
  }

• entityframework.commands: Custom commands

  Example

• entityframework.erDiagram.ignoreTables: A list of tables to ignore from the ER Diagram

  Example

  {
    "entityframework.erDiagram": {
      "ignoreTables": [".*Tracking$"]
    }
  }

• entityframework.env: Custom environment variables

  Example

  {
    "entityframework.env": {
      "ASPNETCORE_ENVIRONMENT": "LocalDev",
      "TenantId": "12345"
    }
  }

When generating an ER diagram, a Mermaid .t4 template will be installed into the project. You can ignore this file (by adding it to .gitignore), or add it to source control. The template file is used to generate the ER Diagram, feel free to customise it. If you delete it, it will be regenerated next time you generate an ER Diagram.

The EF tools execute application code at design time to get information about the project, thus performance on large projects can be slow.
