How do I contribute

If you encounter a bug or have a feature request, please use the Issue Tracker. The project is also open for pull requests following standard pull request guidelines

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.

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.
