This documentation is for EF Core. For EF6.x, see Entity Framework 6.
These 101 tutorials require no previous knowledge of Entity Framework (EF) or Visual Studio. They will take you step-by-step through creating a simple ASP.NET Core application that queries and saves data from a database. You can chose a tutorial that creates a model based on an existing database, or creates a database for you based on your model.
You can find the ASP.NET Core documentation at docs.asp.net.
