Async MySQL Connector for .NET and .NET Core

This is an ADO.NET dataprovider for MySQL. It provides implementations ofDbConnection, DbCommand, DbDataReader, DbTransaction—the classesneeded 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 greatlyimproves the throughput of a web server that performs database operations.

Performance

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

(Client: MySqlConnector 0.44.0, Windows 10 x64; Server: MySQL Server 5.6.21, Unix)

Bug Fixes

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

Build Status

Building

Install the latest .NET Core.

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

dotnet restore
dotnet test tests\MySqlConnector.Tests

To run the side-by-side 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, althoughit will try not to be gratuitously incompatible. For typical scenarios, migrating to this package shouldbe easy.
