Example of implementing a custom logging provider doesn't match .NET 7

[SetTrend]

Trying to reproduce the example from the page, I noticed that the following code snippet doesn't apply to .NET 7:

public static ILoggingBuilder AddColorConsoleLogger(this ILoggingBuilder builder)
  {
    builder.AddConfiguration();

    builder.Services.TryAddEnumerable(ServiceDescriptor.Singleton<ILoggerProvider, ColorConsoleLoggerProvider>());

    LoggerProviderOptions.RegisterProviderOptions<ColorConsoleLoggerConfiguration, ColorConsoleLoggerProvider>builder.Services);

    return builder;
  }

Reasoning

1. There is no extension method adorning the ILoggingBuilder interface with a parameterless AddConfiguration() member:
   
2. builder.Services doesn't provide a TryAddEnumerable method.
3. Where does LoggerProviderOptions all of a sudden come from?

In addition to these issues, the page is missing an explanation on how to retrieve the configured logging level when it may be defined in Default or the custom logger's dedicated configuration section (https://learn.microsoft.com/en-us/aspnet/core/fundamentals/logging/#configure-logging)

Hi there @SetTrend - The source code for this doc (and specifically the code in question) is located here:

https://github.com/dotnet/docs/blob/main/docs/core/extensions/snippets/configuration/console-custom-logging/Extensions/ColorConsoleLoggerExtensions.cs

This project is built using .NET 7, and the LoggerProviderOptions comes from the Microsoft.Extensions.Logging.Configuration namespace.

This is all detailed in the article, did you follow it fully or just parts of it? What specifically should be updated for the article? I'm happy to update it based on your feedback, just want to make sure I capture the correct updates.
