Nightly Builds

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"?>
    <add key="Pomelo" value="" />
    <add key="" value="" />

Getting Started

1. Recommended Server CharSet

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

show variables like 'character_set_database';

2. CSPROJ Configuration

Ensure that your .csproj file contains the following reference:

<PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="3.0.0" />

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;

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

View our Configuration Options Wiki Page for a complete list of supported 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"
