create a localization content management system named eagle in csharp

To create a localization content management system named Eagle in C#, we can follow the below steps:

1. Create a new C# project in Visual Studio with .NET framework version 4.6 or above.
2. Install the required NuGet packages like Newtonsoft.Json, System.Web.Mvc, etc.
3. Create a database for storing the content and localization data using SQL Server.
4. Create an MVC application within the project which will be used as the front-end for managing the content and localization data.
5. Create controllers and views to manage the content data like text, images, videos, etc.
6. Create a separate section to manage the localization data.
7. Use resource files to store the localized strings. You can use different resource files for different languages.
8. Create a model to store the localized data and its respective language.
9. Use Razor views to display the localized content.
10. Create a centralized library to fetch the content and localization data from the database and populate it at runtime.
11. Use localization middleware in C# to manage the preferred language of the user.
12. Write unit tests to test the functionality of the application.

Below is a sample code snippet for handling localization in C#:

main.cs
public class LocalizationMiddleware
{
    private readonly RequestDelegate _next;
 
    public LocalizationMiddleware(RequestDelegate next)
    {
        _next = next;
    }
 
    public async Task InvokeAsync(HttpContext context, IOptions<RequestLocalizationOptions> options)
    {
        var requestCulture = context.Features.Get<IRequestCultureFeature>();
        var culture = requestCulture.RequestCulture.UICulture.TwoLetterISOLanguageName;
 
        if (!string.IsNullOrEmpty(culture))
        {
            CultureInfo.CurrentCulture = new CultureInfo(culture);
            CultureInfo.CurrentUICulture = new CultureInfo(culture);
        }
 
        await _next(context);
    }
}
