What is Session Management in ASP.NET Core?

Session Management in ASP.NET Core allows developers to store and retrieve user-specific data across multiple requests. It is useful for maintaining user state, such as login information, shopping cart items, or preferences.

Key Features:

• Stores data temporarily for a user session
• Supports in-memory, distributed, and custom session stores
• Easy integration with controllers and Razor Pages
• Works with cookies to track sessions
• Improves user experience and state management

Example:
Configure session in Program.cs:

builder.Services.AddDistributedMemoryCache();
builder.Services.AddSession(options =>
{
    options.IdleTimeout = TimeSpan.FromMinutes(30);
    options.Cookie.HttpOnly = true;
    options.Cookie.IsEssential = true;
});

var app = builder.Build();
app.UseSession();

Using session in a controller:

public IActionResult SetSession()
{
    HttpContext.Session.SetString("Username", "Sagar");
    return Content("Session set!");
}

public IActionResult GetSession()
{
    var username = HttpContext.Session.GetString("Username");
    return Content($"Username from session: {username}");
}

Session Management in ASP.NET Core enables tracking of user data across requests, improving interactivity and personalization in web apps.
