Localizing a minimal API application

To enable localization within a minimal API application, let us go through the following steps:

1. The first step to making an application localizable is to specify the supported cultures by setting the corresponding options, as follows:

   var builder = WebApplication.CreateBuilder(args);
   //...
   var supportedCultures = new CultureInfo[] { new("en"), new("it"), new("fr") };
   builder.Services.Configure<RequestLocalizationOptions>(options =>
   {

In our example, we want to support three cultures – English, Italian, and French – so, we create an array of CultureInfo objects.

We’re defining neutral cultures, that is, cultures that have...
