Installing Entity Framework Core

In this tutorial, learn the various ways to install the Entity Framework Core. We can use the Entity Framework Core with both .NET Core & .NET Framework.

Supported Frameworks

Before installing it is important to know the how EF Core is supported in various frameworks.

EF Core 5.0. .NET Standard 2.1 & .NET Core 3.0

EF Core 3.1 .NET Standard 2.0 & NET Core 2.0

FF Core 2.1 .NET Standard 2.0 & NET Core 2.0

What to Install

The Microsoft.EntityFrameworkCore is the core library. But installing that alone is not sufficient. We also need to install the EF Core database provider(s). For Example, to use the SQL Server, we need to install the Microsoft.EntityFrameworkCore.SqlServer. For SQLite install the Microsoft.EntityFrameworkCore.Sqlite. When we install the database provider(s) , they automatically install the Microsoft.EntityFrameworkCore.

The following are the some of the database provider(s)

  • Microsoft.EntityFrameworkCore.InMemory
  • Npgsql.EntityFrameworkCore.PostgreSQL
  • Pomelo.EntityFrameworkCore.MySql (for both Mysql & MariaDB)
  • MySql.Data.EntityFrameworkCore (Official version for MySQL)
  • Oracle.EntityFrameworkCore
  • EntityFrameworkCore.Jet (Microsoft Access)

We also need to install the Entity Framework Core tools. These tools contain the help us to create migrations, apply migrations, and generate code for a model based on an existing database. The tools are available in the package Microsoft.EntityFrameworkCore.Tools.
