MySqlConnector: High Performance .NET MySQL Driver

About

MySqlConnector is a C# ADO.NET driver for MySQL Server, MariaDB, Amazon Aurora, Azure Database for MySQL, Google Cloud SQL for MySQL, Percona Server and more. It provides implementations of DbConnection, DbCommand, DbDataReader, DbTransaction — the classes needed to query and update databases from C# code.

Getting Started

Install MySqlConnector from NuGet: dotnet add package MySqlConnector

Connecting to your database is simple. For example, in C#:

using var connection = new MySqlConnection("Server=myserver;User ID=mylogin;Password=mypass;Database=mydatabase");
connection.Open();

using var command = new MySqlCommand("SELECT field FROM table;", connection);
using var reader = command.ExecuteReader();
while (reader.Read())
    Console.WriteLine(reader.GetString(0));

For more information, see how to install and a basic example of using the API. Many ORMs are supported.

Asynchronous I/O

MySqlConnector also fully supports asynchronous I/O. The C# example above can be rewritten as:

await using var connection = new MySqlConnection("Server=myserver;User ID=mylogin;Password=mypass;Database=mydatabase");
await connection.OpenAsync();

using var command = new MySqlCommand("SELECT field FROM table;", connection);
await using var reader = await command.ExecuteReaderAsync();
while (await reader.ReadAsync())
    Console.WriteLine(reader.GetString(0));

Performance

MySqlConnector outperforms 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)

Why use MySqlConnector over Oracle’s MySQL Connector/NET?

MySqlConnector is a clean-room reimplementation of the MySQL Protocol and is not based on Oracle’s MySQL Connector/NET.

• Asynchronous: True asynchronous I/O for maximum throughput
• Fast: Optimized for speed and low memory usage
• Reliable: Fixes dozens of open bugs in Oracle’s Connector/NET; passes all ADO.NET Specification Tests
• Leading Edge: First MySQL library to support .NET Core; uses the latest .NET features
• Open: MIT license; development happens on GitHub with publicly visible roadmaps, issues, and PRs
