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

Pomelo.EntityFrameworkCore.MySql
is tested against all actively maintained versions of MySQL
and MariaDB
. Older versions (e.g. MySQL 5.7) and other server implementations (e.g. Amazon Aurora) are usually compatible to a high degree as well, but are not tested as part of our CI.
Officially supported versions are:

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-nightly" 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>
Feeds that contain optimized (Release
configuration) builds:
https://pkgs.dev.azure.com/pomelo-efcore/Pomelo.EntityFrameworkCore.MySql/_packaging/pomelo-efcore-public/nuget/v3/index.json
https://www.myget.org/F/pomelo/api/v3/index.json
Feeds that contain debugging enabled unoptimized (Debug
configuration) builds:
https://pkgs.dev.azure.com/pomelo-efcore/Pomelo.EntityFrameworkCore.MySql/_packaging/pomelo-efcore-debug/nuget/v3/index.json
https://www.myget.org/F/pomelo-debug/api/v3/index.json
The AZDO nupkg
packages always contain .pdb
files.
The MyGet nupkg
packages only contain .pdb
files for their debug builds. For optimized builds, the symbols are packed in a snupkg
file and are available via the https://www.myget.org/F/pomelo/api/v2/symbolpackage/
symbol server URL.
All .pdb
files use Source Link.
Ensure that your .csproj
file contains the following reference:
<PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="8.0.2" />
Add Pomelo.EntityFrameworkCore.MySql
to the services configuration in your the Startup.cs
file of your ASP.NET Core project:
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, 36));
// Replace 'YourDbContext' with the name of your own DbContext derived class.
services.AddDbContext<YourDbContext>(
dbContextOptions => dbContextOptions
.UseMySql(connectionString, serverVersion)
// The following three options help with debugging, but should
// be changed or removed for production.
.LogTo(Console.WriteLine, LogLevel.Information)
.EnableSensitiveDataLogging()
.EnableDetailedErrors()
);
}
}
View our Configuration Options Wiki Page for a list of common options.
Check out our Integration Tests for an example repository that includes an ASP.NET Core MVC Application.
There are also many complete and concise console application samples 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;User=root;Password=1234;Database=ef" "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.
