nHydrate ORM for Entity Framework Core

This platform creates strongly-typed, extendable classes for Entity Framework. The generated code is Entity Framework Core. There is no difference. This is not a replacement for EF or a custom ORM. It is a visual, modeling layer that allows a team to manage complex database schemas. It works well with SCM software like Git, allowing multi-user access to your model with minimal conflicts.

Running the code

To load and compile this project you need Visual Studio 2017 or greater. When installing Visual Studio, be sure to include the Modeling SDK. You can then load and build the solution.

When you build, the plugin will be automatically be installed as an extension in the Experimental Hive. You will not see the extension in the main Visual Studio setup. You must open Visual Studio as Experimental Hive. The Experimental Hive is a copy of Visual Studio with fresh settings that can be reset if needed. It is automatically installed and configured when you have the Modeling SDK on your machine.

You can’t perform that action at this time.
