# EF Core Power Tools



Reverse engineering, model visualization and migrations UI for EF Core in Visual Studio 2022 (amd64)  - and reverse engineering from command line.



Aims to lower the bar for getting started with EF Core, by providing GUI based assistance with reverse engineering of an existing database, creating migrations and visualizing your DbContext model.

# Downloads/builds



## Requirements 



.NET Framework 4.8 or later is required. For EF Core reverse engineering, the .NET 6.0 or .NET 8.0 x64 runtime must be installed.



## Release



Download the latest version of the Visual Studio extension from [Visual Studio MarketPlace](https://marketplace.visualstudio.com/items?itemName=ErikEJ.EFCorePowerTools)



Or simply install from the Extensions dialog in Visual Studio.



I have also published [EF Core Power Pack](https://marketplace.visualstudio.com/items?itemName=ErikEJ.EFCorePowerPack) which includes some helpful DDEX providers as well as EF Core Power Tools.



## Daily build



You can download the daily build from [Open VSIX Gallery](https://www.vsixgallery.com/extension/f4c4712c-ceae-4803-8e52-0e2049d5de9f)



Ensure you always have the latest daily build (if you are brave) by installing [this extension](https://marketplace.visualstudio.com/items?itemName=MadsKristensen.VSIXGallery-nightlybuilds)



## Cross platform command line tool - efcpt



If you do not use Visual Studio, but for example Visual Studio Code, a cross platform dotnet tool for reverse engineering is available, more information [here](https://github.com/ErikEJ/EFCorePowerTools/blob/master/src/GUI/efcpt.7/readme.md)



## Related NuGet packages



[ErikEJ.EntityFrameworkCore.DgmlBuilder](https://github.com/ErikEJ/EFCorePowerTools/blob/master/src/GUI/ErikEJ.EntityFrameworkCore.DgmlBuilder/readme.md)



Adds the AsDgml() extension method to any derived DbContext. The method will create a DGML graph of your DbContext Model, that you can then view in the Visual Studio DGML viewer



[ErikEJ.EntityFrameworkCore.SqlServer.Dacpac](https://github.com/ErikEJ/EFCorePowerTools/blob/master/src/GUI/ErikEJ.EntityFrameworkCore.SqlServer.Dacpac/readme.md)



Reverse engineer a SQL Server .dacpac with the EF Core tooling

# Building and debugging



To build and debug, run latest version of Visual Studio as Administrator with the "Visual Studio extension development workload" installed. Make EFCorePowerTools the startup project, and ensure your build configuration is Debug, AnyCPU.



# Smoke testing changes to reverse engineering

You can smoke test changes to reverse engineering. Launch one of the efreveng console apps in the debugger using the name of a file in the TestFiles folder as parameter.



In the ScaffoldingTester solution there are scripts to populate Northwind and Chinook databases with the required objects.
