Run efvibe inside VS Code — evaluate EF Core LINQ against your real DbContext, see translated and executed SQL, scan the repo, and open an interactive REPL. Works with most EF Core relational providers (SQL Server, PostgreSQL, SQLite, Oracle, MySQL/MariaDB, Firebird, and others discovered from your EF project). Maps workspace settings to CLI -p, -s, and -c.

Prerequisites

.NET SDK (same major version as your EF project)
efvibe CLI on PATH: dotnet tool install -g efvibe
Workspace settings: efvibe.project, efvibe.context (and usually efvibe.startupProject)

Run Selection, model tree (tables / describe / DbInfo), scan, and db.* completions use efvibe serve by default (efvibe.useDaemon: true) so build + DbContext stay warm.

Database providers

The extension uses the same provider model as the CLI:

The provider is auto-discovered from efvibe.project PackageReference entries.
efvibe.startupProject supplies connection strings from user secrets / appsettings — same split as dotnet ef.
Optional efvibe.connectionString overrides the connection string; the provider is still discovered from -p.

See docs/database-providers.md for feature tiers, :plan support, and platform notes.

Quick start

{
  "efvibe.project": "${workspaceFolder}/src/MyApp.Data/MyApp.Data.csproj",
  "efvibe.startupProject": "${workspaceFolder}/src/MyApp.Api/MyApp.Api.csproj",
  "efvibe.context": "AppDbContext",
  "efvibe.dotnetFramework": "net8.0"
}

Command Palette → efvibe: Check Prerequisites → efvibe: Run Selection on a db.* query.

Notebooks

Use efvibe: New Notebook or create a *.efvibe-notebook file. Code cells run through the configured DbContext using efvibe serve / JSON evaluation and keep rows, SQL, metrics, warnings, and query plans attached to the cell. The notebook has two controllers: efvibe and efvibe :plan.

Supported command cells:

:dbinfo
:tables
