Async MySQL Connector for .NET and .NET Core
This is an ADO.NET data
provider for MySQL. 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?
Async Support
This library implements true asynchronous I/O for database operations, without blocking
(or using Task.Run to run synchronous methods on a background thread). This greatly
improves the throughput of a web server that performs database operations.
Performance
This library outperforms MySQL Connector/NET (MySql.Data) on benchmarks:
(Client: MySqlConnector 2.2.0, Ubuntu 20.04, .NET 7.0; Server: Azure Database for MySQL 8.0.28, TLS 1.2)
Bug Fixes
This library fixes dozens of outstanding bugs in Connector/NET.
License
This library is MIT-licensed and may be freely distributed with commercial software. Commercial software that uses Connector/NET may have to purchase a commercial license from Oracle.
ORMs
This library is compatible with popular .NET ORMs including:
- Dapper (GitHub, NuGet)

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:
- .NET Standard support: It must run on the full .NET Framework and all platforms supported by .NET Core.
- Async: All operations must be truly asynchronous whenever possible.
- High performance: Avoid unnecessary allocations and copies when reading data.
- Lightweight: Only the core of ADO.NET is implemented, not EF or Designer types.
- Managed: Managed code only, no native code.
- 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.
