Customizing the User Experience within ASP

• How to use sessions:
  • Set session data:
    

    HttpContext.Session.SetString("UserName", "JohnDoe");
    

  • Get session data:
    

    var userName = HttpContext.Session.GetString("UserName");
    

• Customization example: You can track a user's preferences (e.g., theme, language) across their visit by saving their choices in a session and modifying the UI accordingly.

• How to use cookies:
  
  • Set cookie:
    

    var cookieOptions = new CookieOptions
    {
     Expires = DateTime.Now.AddDays(7)
    };
    Response.Cookies.Append("Theme", "DarkMode", cookieOptions);
    

  • Get cookie:
    

    var theme = Request.Cookies["Theme"];
    

• Customization example: Use cookies to remember a user's selected theme or preferences so the website will load with their choices when they return.

• Customization example: You can display different content or layouts based on the user’s role (admin, user, guest), or show personalized dashboards with user-specific data.
• Basic setup:
  
  • Use `SignInManager` to sign users in and track them.

        var result = await _signInManager.PasswordSignInAsync(userName, password, isPersistent, lockoutOnFailure);
        

  • Display different content based on roles:

        if (User.IsInRole("Admin")) 
        {
            // Show admin-specific content
        }
        else 
        {
            // Show general user content
        }
        

ASP.NET supports profile properties, which allow you to persist user-specific data across sessions.
• Setting up profiles in Web.config:

    <profile>
      <properties>
        <add name="PreferredLanguage" type="String" />
        <add name="Theme" type="String" />
      </properties>
    </profile>
    

• Accessing profile data in code:

    Profile["PreferredLanguage"] = "English";
    var language = (string)Profile["PreferredLanguage"];
    

• Customization example: You can store user preferences such as language and display customized content based on their stored profile information.

• Using Razor Pages: You can return different content from `Razor Pages` based on the user’s context, such as their preferences or role.

public IActionResult Index()
{
    string userName = HttpContext.Session.GetString("UserName") ?? "Guest";
    ViewBag.UserName = userName;
    return View();
}

<h2>Welcome, @ViewBag.UserName!</h2>
