How to split the Options Configured in Startup

I have a .Net Core project where I Configured different options. Now it looks more complex, so I need to split each in to different methods.

For Example I registered mongo db credentials options and I need to move this to simple extension methods:

services.Configure<DataAccess.MongoDB.Contracts.AppSettings.MongoDBSettings> options =>
        {
            options.ConnectionString
                = GetConfigurationSection("MongoConnection:ConnectionString");
            options.Database
                = GetConfigurationSection("MongoConnection:Database");
        });

Expected something like this:

services.ConfigureMongoDbSettings();

Move your code to a class like this (you can name it whatever you like):

public static class MongoDbSettingsCollectionExtensions {
    public static IServiceCollection ConfigureMongoDbSettings(
                  this IServiceCollection services,
                  IConfiguration Configuration) {
      services.Configure<DataAccess.MongoDB.Contracts.AppSettings.MongoDBSettings> options =>
        {
            options.ConnectionString
                = Configuration.GetConfigurationSection("MongoConnection:ConnectionString");
            options.Database
                = Configuration.GetConfigurationSection("MongoConnection:Database");
        });
      return services;
    }
}

This will allow you to call it in Startup as you suggested:

services.ConfigureMongoDbSettings(Configuration);

Alternatively, you can pass it the configuration section itself which is what the Core team did with some services:

services.ConfigureMongoDbSettings(Configuration.GetConfigurationSection("MongoConnection"));

Obviously, in this way you'll have to change the ConfigureMongoDbSettings() function above to receive and work directly with the configuration section.
