MySQL Connector for .NET and .NET Core

This is an ADO.NET data provider for MySQL and other compatible servers including MariaDB. It provides implementations of DbConnection, DbCommand, DbDataReader, DbTransaction—the classes needed to query and update databases from managed code.

Complete documentation is available at the MySqlConnector Documentation Website.

Why Use This Library?

Performance

This library outperforms MySQL Connector/NET (MySql.Data) on benchmarks:

(Client: MySqlConnector 3.0.0, MySql.Data 26.10.0, Ubuntu 24.04, .NET 11.0; Server: Azure Database for MySQL 8.4.11, TLS 1.3)

Server Compatibility

This library is compatible with many MySQL-compatible servers, including MySQL 5.5 and newer and MariaDB 10.x and newer. MySql.Data only supports MySQL Server.

Bug Fixes

This library fixes dozens of outstanding bugs in Connector/NET.

Cutting Edge

This library implements the latest ADO.NET APIs, from async (introduced in .NET Framework 4.5), through DbBatch (.NET 6.0) and DbDataSource (.NET 7.0).

Build Status

Building

Install the latest .NET.

To build and run the tests, clone the repo and execute:

dotnet restore
dotnet test tests\MySqlConnector.Tests

To run the integration tests, see the instructions.

Goals

The goals of this project are:

1. .NET Standard support: It must run on the full .NET Framework and all platforms supported by .NET Core.
2. Async: All operations must be truly asynchronous whenever possible.
3. High performance: Avoid unnecessary allocations and copies when reading data.
4. Lightweight: Only the core of ADO.NET is implemented, not EF or Designer types.
5. Managed: Managed code only, no native code.
6. Independent: This is a clean-room reimplementation of the MySQL Protocol, not based on Connector/NET.

Cloning the full API of Connector/NET is not a goal of this project, although it will try not to be gratuitously incompatible. For typical scenarios, migrating to this package should be easy.
