Pomelo.EntityFrameworkCore.MySql is an Entity Framework Core provider built on top of MySqlConnector that enables the use of the Entity Framework Core ORM with MySQL.

Pomelo.EntityFrameworkCore.MySql is currently looking for core contributors

To use nightly builds from our MyGet feed, add a NuGet.config file in your solution root with the following contents:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="Pomelo" value="https://www.myget.org/F/pomelo/api/v3/index.json" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

We recommend you to set utf8mb4 as your MySQL database default charset. The following statement will check your DB charset:

show variables like 'character_set_database';

Ensure that your .csproj file has the following references.

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.2</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" Version="2.2.0" />
    <PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="2.2.0" />
  </ItemGroup>
  
</Project>

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

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

namespace YourNamespace // replace "YourNamespace" with the namespace of your application
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            // other service configurations go here
            services.AddDbContextPool<YourDbContext>( // replace "YourDbContext" with the class name of your DbContext
                options => options.UseMySql("Server=localhost;Database=ef;User=root;Password=123456;", // replace with your Connection String
                    mySqlOptions =>
                    {
                        mySqlOptions.ServerVersion(new Version(5, 7, 17), ServerType.MySql); // replace with your Server Version and Type
                    }
            ));
        }
    }
}

The escaping style can be configured to support SQL mode NO_BACKSLASH_ESCAPES by adding .DisableBackslashEscaping() to your MySQL option configuration.

mysqlOptions =>
{
    mysqlOptions
    .ServerVersion(new Version(5, 7, 17), ServerType.MySql); // replace with your Server Version and Type
    //further MySQL option configurations go here
    .DisableBackslashEscaping();
}

PLEASE NOTE This option does not set the SQL mode and will not check if it matches the actual database configuration either. Do not use this option unless you are absolutely sure it will always be set when queries are performed on the context. As of today, it also does not apply to parameter values in insert or update statements; do not use it when the context is used to update entries.

View our MySql Provider Configuration Options Wiki Page for a complete list of supported options.

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