Pomelo.EntityFrameworkCore.MySql is the most popular Entity Framework Core provider for MySQL compatible databases. It supports EF Core up to its latest version and uses MySqlConnector for high-performance database server communication.

The following versions of MySqlConnector, EF Core, .NET (Core), .NET Standard and .NET Framework are compatible with Pomelo.EntityFrameworkCore.MySql:

• Pomelo.EntityFrameworkCore.MySql
• Pomelo.EntityFrameworkCore.MySql.Json.Microsoft
• Pomelo.EntityFrameworkCore.MySql.Json.Newtonsoft
• Pomelo.EntityFrameworkCore.MySql.NetTopologySuite

Pomelo.EntityFrameworkCore.MySql is tested at least against the latest 2 minor versions of MySQL and MariaDB. Older versions and other server implementations (e.g. Amazon Aurora) may be compatible (and likely are to a high degree) but are not officially supported or tested.

Currently supported versions are:

• MySQL 8.0
• MySQL 5.7
• MariaDB 10.5
• MariaDB 10.4
• MariaDB 10.3

To use nightly builds from our Azure DevOps feed, add a NuGet.config file to your solution root with the following content and enable prereleases:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="Pomelo" value="https://pkgs.dev.azure.com/pomelo-efcore/Pomelo.EntityFrameworkCore.MySql/_packaging/pomelo-efcore-public/nuget/v3/index.json" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

Ensure that your .csproj file contains the following reference:

<PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="5.0.1" />

Add Pomelo.EntityFrameworkCore.MySql to the services configuration in your the Startup.cs file.

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // Replace with your connection string.
        var connectionString = "server=localhost;user=root;password=1234;database=ef";

        // Replace with your server version and type.
        // Use 'MariaDbServerVersion' for MariaDB.
        // Alternatively, use 'ServerVersion.AutoDetect(connectionString)'.
        // For common usages, see pull request #1233.
        var serverVersion = new MySqlServerVersion(new Version(8, 0, 25));

        // Replace 'YourDbContext' with the name of your own DbContext derived class.
        services.AddDbContext<YourDbContext>(
            dbContextOptions => dbContextOptions
                .UseMySql(connectionString, serverVersion)
                .EnableSensitiveDataLogging() // <-- These two calls are optional but help
                .EnableDetailedErrors()       // <-- with debugging (remove for production).
        );
    }
}

Check out our Integration Tests for an example repository that includes an MVC Application.

There are also many complete and concise sample console applications posted in the issue section (some of them can be found by searching for Program.cs).

Refer to Microsoft's EF Core Documentation for detailed instructions and examples on using EF Core.

Use the EF Core tools to execute scaffolding commands:

dotnet ef dbcontext scaffold "Server=localhost;Database=ef;User=root;Password=123456;TreatTinyAsBoolean=true;" "Pomelo.EntityFrameworkCore.MySql"

One of the easiest ways to contribute is to report issues, participate in discussions and update the wiki docs. You can also contribute by submitting pull requests with code changes and supporting tests.

We are always looking for additional core contributors. If you got a couple of hours a week and know your way around EF Core and MySQL, give us a nudge.
