MySqlConnector.DependencyInjection 2.3.0-beta.1

About

MySqlConnector.DependencyInjection helps set up MySqlConnector in applications that use dependency injection, most notably in ASP.NET. It allows easy configuration of your MySQL connections and registers the appropriate services in your DI container.

How to Use

For example, if using the ASP.NET minimal web API, use the following to register MySqlConnector:

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddMySqlDataSource("Server=server;User ID=test;Password=test;Database=test");

This registers a transient MySqlConnection which can get injected into your controllers:

app.MapGet("/", async (MySqlConnection connection) =>
{
    await connection.OpenAsync();
    await using var command = connection.CreateCommand();
	command.CommandText = "SELECT name FROM users LIMIT 1";
    return "Hello World: " + await command.ExecuteScalarAsync();
});

You can use MySqlDataSource directly if you need more than one connection:

app.MapGet("/", async (MySqlDataSource dataSource) =>
{
    await using var connection1 = await dataSource.OpenConnectionAsync();
    await using var connection2 = await dataSource.OpenConnectionAsync();
    // use the two connections...
});

Advanced Usage

The AddMySqlDataSource method also accepts a lambda parameter allowing you to configure aspects of MySqlConnector beyond the connection string.

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddMySqlDataSource("Server=server;User ID=test;Password=test;Database=test",
	x => x.UseRemoteCertificateValidationCallback((sender, certificate, chain, sslPolicyErrors) => { /* custom logic */ })
);
