About this capability

Implementation details for the EF Core dotnet-ef CLI and tooling. Use when changing dotnet-ef commands, the ef wrapper, EFCore.Tools (PMC), or EFCore.Tasks MSBuild integration.

What this skill tells your AI

The instructions your AI receives, as published by dotnet/efcore in .agents/skills/tooling/SKILL.md and read by ahel’s review.

The dotnet ef CLI and Visual Studio Package Manager Console commands for migrations, scaffolding, and compiled models.

dotnet-ef CLI (src/dotnet-ef/)

RootCommand parses global options. Subcommands implemented in src/ef/Commands/. Each invokes MSBuild to build, then shells out via dotnet exec ef.dll, which hosts OperationExecutor.

PMC (src/EFCore.Tools/)

PowerShell module: Add-Migration, Update-Database, Scaffold-DbContext, Optimize-DbContext, etc.

MSBuild Tasks (src/EFCore.Tasks/)

NuGet package Microsoft.EntityFrameworkCore.Tasks provides build/publish-time compiled model and precompiled query generation. Targets in buildTransitive/Microsoft.EntityFrameworkCore.Tasks.targets.

Testing

  • CLI tests: test/dotnet-ef.Tests/, test/ef.Tests/
  • EFCore.Tasks has no dedicated test project — for task/target changes, create a test project and manually run dotnet build / dotnet publish with EFOptimizeContext=true to verify

Validation

  • For tool changes, create a test project and manually run affected commands to verify behavior
  • dotnet ef migrations script output matches expected DDL
