Nightly Builds

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>

Getting Started

1. Recommended Character Set

We recommend to set utf8mb4 as your MySQL database default character set. This is already the server default in MySQL 8. The following statement will check the charset of the current database:

show variables like 'character_set_database';

2. Project Configuration

Ensure that your .csproj file contains the following reference:

<PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="5.0.0-alpha.2" />

3. Services Configuration

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

using System;
using Microsoft.EntityFrameworkCore;
using Pomelo.EntityFrameworkCore.MySql.Infrastructure;

// Replace "YourNamespace" with the namespace of your application.
namespace YourNamespace
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            // Replace "YourDbContext" with the name of your own DbContext derived class.
            services.AddDbContextPool<YourDbContext>(
                dbContextOptions => dbContextOptions
                    .UseMySql(
                        // Replace with your connection string.
                        "server=localhost;user=root;password=1234;database=ef",
                        // Replace with your server version and type.
                        // For common usages, see pull request #1233.
                        new MySqlServerVersion(new Version(8, 0, 21)), // use MariaDbServerVersion for MariaDB
                        mySqlOptions => mySqlOptions
                            .CharSetBehavior(CharSetBehavior.NeverAppend))
                    // Everything from this point on is optional but helps with debugging.
                    .EnableSensitiveDataLogging()
                    .EnableDetailedErrors();
            ));
        }
    }
}

View our Configuration Options Wiki Page for a list of common options.

4. Sample Application

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

5. Read the EF Core Documentation

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

Scaffolding / Reverse Engineering

Use the EF Core tool to execute scaffolding commands:

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

Contribute

One of the easiest ways to contribute is to report issues and participate in discussions. 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.
