In ASP.NET Core, sessions provide a way to store and retrieve user-specific information across multiple requests. Sessions can be used to persist data, such as user preferences or authentication details, throughout a user's interaction with your application. Here's a basic guide on how to use sessions in ASP.NET Core:
Configure Session in Startup.cs:
In the Startup.cs
file, you need to configure the session services. This involves adding the session middleware and specifying the session storage mechanism. For example, you can use in-memory storage during development:
// Inside the ConfigureServices method public void ConfigureServices(IServiceCollection services) { services.AddDistributedMemoryCache(); // In-memory storage for development services.AddSession(options => { options.IdleTimeout = TimeSpan.FromMinutes(30); // Set the session timeout options.Cookie.HttpOnly = true; options.Cookie.IsEssential = true; }); // Other service configurations... }
Use Sessions in Controllers or Views:
Once the session is configured, you can access it in your controllers or views. Sessions can be accessed through the HttpContext.Session
property.
// In a controller action method public IActionResult SetSession() { HttpContext.Session.SetString("UserName", "JohnDoe"); return RedirectToAction("Index"); } public IActionResult GetSession() { string userName = HttpContext.Session.GetString("UserName"); // Do something with the user name... return View(); }
Accessing Sessions in Razor Views:
You can also access sessions directly in your Razor views:
<!-- In a Razor view --> @{ string userName = Context.Session.GetString("UserName"); } <p>Welcome, @userName!</p>
Enabling Session State in the Startup.cs Configure method:
Finally, you need to add the session middleware to the request processing pipeline in the Configure
method of Startup.cs
:
// Inside the Configure method public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { // Other middleware configurations... app.UseSession(); // More middleware configurations... }
With these steps, you should be able to use sessions in your ASP.NET Core application. Keep in mind that in a production environment, you might want to use a more robust session storage provider, such as a distributed cache, to handle scenarios where your application is deployed across multiple servers.

Creating and using custom authentication in ASP.NET Core involves implementing your own authentication scheme. Here's a basic guide on how to create a custom authentication scheme in ASP.NET Core:
Create a Custom Authentication Handler:
Start by creating a custom authentication handler by inheriting from the AuthenticationHandler<TOptions>
class. This class provides the basic infrastructure for handling authentication.
public class CustomAuthenticationHandler : AuthenticationHandler<CustomAuthenticationOptions> { public CustomAuthenticationHandler(IOptionsMonitor<CustomAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock) : base(options, logger, encoder, clock) { } protected override async Task<AuthenticateResult> HandleAuthenticateAsync() { // Implement your authentication logic here // Retrieve credentials from the request, validate them, and create a ClaimsPrincipal // Example: var claims = new List<Claim> { new Claim(ClaimTypes.Name, "JohnDoe"), // Add other claims as needed }; var identity = new ClaimsIdentity(claims, Scheme.Name); var principal = new ClaimsPrincipal(identity); var ticket = new AuthenticationTicket(principal, Scheme.Name); return AuthenticateResult.Success(ticket); } }
Create Custom Authentication Options:
Define a class for custom authentication options by inheriting from AuthenticationSchemeOptions
. This class can contain any configuration properties needed for your authentication scheme.
public class CustomAuthenticationOptions : AuthenticationSchemeOptions { // Add any custom properties/configuration needed for your authentication scheme }
Register Custom Authentication in Startup.cs:
In the Startup.cs
file, add the custom authentication scheme during the ConfigureServices
method:
public void ConfigureServices(IServiceCollection services) { // Other service configurations... services.AddAuthentication(CustomAuthenticationOptions.DefaultScheme) .AddScheme<CustomAuthenticationOptions, CustomAuthenticationHandler>("CustomScheme", options => { /* configure options if needed */ }); // More service configurations... }
Use Custom Authentication in Controllers:
In your controllers or action methods, use the Authorize
attribute with your custom authentication scheme name.
[Authorize(AuthenticationSchemes = "CustomScheme")] public IActionResult SecureAction() { // This action is protected by your custom authentication scheme return View(); }
You can also enforce authentication programmatically in your code:
var result = await HttpContext.AuthenticateAsync("CustomScheme"); if (!result.Succeeded) { // Handle authentication failure return Challenge("CustomScheme"); } // Continue processing for authenticated user
Configure Authentication Middleware:
In the Configure
method of Startup.cs
, add the authentication middleware to the request processing pipeline:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { // Other middleware configurations... app.UseAuthentication(); app.UseAuthorization(); // More middleware configurations... }
Now, you have a basic custom authentication scheme in place. Customize the CustomAuthenticationHandler
to fit your specific authentication logic, such as validating user credentials, creating a ClaimsPrincipal
, and issuing authentication tickets. Additionally, you can add more advanced features, such as handling authentication challenges and events.

Entity Framework Code-First is an approach in Entity Framework, a data access technology in the Microsoft .NET ecosystem, where you define your data model using plain old C# classes (POCO) and conventions, and the database schema is generated automatically based on these classes. This is in contrast to the Database-First or Model-First approaches, where the database schema is designed first, and then the data model classes are generated from it.
Here are the key steps and concepts involved in the Entity Framework Code-First approach:
Define Entity Classes:
public class Blog { public int BlogId { get; set; } public string Title { get; set; } public string Content { get; set; } public ICollection<Post> Posts { get; set; } } public class Post { public int PostId { get; set; } public string Title { get; set; } public string Content { get; set; } public int BlogId { get; set; } public Blog Blog { get; set; } }
Create a Database Context:
DbContext
. This class represents the database context and includes properties for each entity set.public class BlogDbContext : DbContext { public DbSet<Blog> Blogs { get; set; } public DbSet<Post> Posts { get; set; } }
Configure the Database Connection:
services.AddDbContext<BlogDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
Enable Migrations:
dotnet ef migrations add InitialCreate
Apply Migrations:
dotnet ef database update
Use the Database Context in Code:
using (var context = new BlogDbContext()) { var blog = new Blog { Title = "Code-First Approach", Content = "Entity Framework Code-First" }; context.Blogs.Add(blog); context.SaveChanges(); }
Entity Framework Code-First provides a flexible and intuitive way to define your data model using C# classes, and it automatically generates the corresponding database schema. It is particularly well-suited for scenarios where the application's domain model is the primary focus and can evolve independently of the database schema.

Visual Studio is primarily designed for development in .NET languages, and C# is one of the main languages used within the .NET ecosystem. While C# itself is tightly integrated with the .NET libraries and runtime, you can certainly write code in C# without relying on specific .NET libraries or classes, but it's important to understand some aspects of the language and tooling.
Here are a few considerations:
1. **Console Applications:**
- You can create console applications in C# without relying on extensive .NET libraries. A simple console application may only use basic language features without delving into the broader .NET framework.
2. **Limiting Dependencies:**
- While you can write C# code without relying on many .NET libraries, some minimal dependencies are typically required for basic functionality. For example, input and output operations often rely on the `System` namespace, and you may use the `System.Console` class for console interactions.
3. **Language Features:**
- C# itself is a rich and expressive language, providing features such as classes, structs, interfaces, generics, and more. You can leverage these language features without necessarily using advanced .NET libraries.
4. **Targeting .NET Core or .NET 5+ for Lightweight Applications:**
- If you want to avoid the full set of .NET libraries and target a more lightweight framework, you can use .NET Core or .NET 5+ with a minimal set of dependencies. This allows you to create console applications with reduced reliance on the broader .NET framework.
5. **Use of C# as a Scripting Language:**
- With the introduction of C# scripting (using .csx files), you can write C# code in a script-like manner, without having to create a full-fledged project. This can be useful for experimenting with C# code without relying on extensive libraries.
Here's a simple example of a console application in C#:
```csharp
using System;
class Program
{
static void Main()
{
Console.WriteLine("Hello, C# without extensive libraries!");
// Your code here without relying on additional libraries
}
}
```
Keep in mind that while you can minimize your reliance on .NET libraries, it's often beneficial to leverage the extensive libraries and frameworks provided by the .NET ecosystem for practical application development. If your goal is to write code without any dependencies, you might explore other languages that are designed to be more lightweight and independent.
