 ## 3. Configure Service (ASP.NET Core)
 
-### .NET 6.0

 If using ASP.NET Core, you will want to register a database connection in `Program.cs`:
 
+**Recommended** Install [MySqlConnector.DependencyInjection](https://www.nuget.org/packages/MySqlConnector.DependencyInjection/) via `dotnet add package MySqlConnector.DependencyInjection`. Then add the following to `Program.cs`:
+
 ```csharp
-builder.services.AddTransient<MySqlConnection>(_ =>
-    new MySqlConnection(builder.Configuration.GetConnectionString["Default"]));
+builder.Services.AddMySqlDataSource(builder.Configuration.GetConnectionString("Default")!);
 ```
 
-### .NET 5.0 and earlier
-
-For .NET 5.0 and earlier, register a database connection in `Startup.cs`:
+Alternatively, register a transient `MySqlConnection` object explicitly:
 
 ```csharp
-public void ConfigureServices(IServiceCollection services)
-{
-    // ...
-    services.AddTransient<MySqlConnection>(_ => new MySqlConnection(Configuration["ConnectionStrings:Default"]));
-}
+builder.services.AddTransient<MySqlConnection>(_ =>
+    new MySqlConnection(builder.Configuration.GetConnectionString["Default"]));
 ```
 
+The advantage of using `AddMySqlDataSource` is that it will automatically integrate with logging, and also register `DbDataSource` and `DbConnection` with the service collection.
