Beginner‘s Guide to Dynamic Website Development181

is an open-source web application framework developed by Microsoft that allows developers to build dynamic, interactive, and secure web applications using the .NET programming language. In this tutorial, we will provide a comprehensive overview of the fundamentals of dynamic website development for beginners.

Creating an Project

To create an project, you will need to have Visual Studio installed on your computer. Once you have Visual Studio open, follow these steps:
Click on "File" > "New" > "Project..."
Select " Core Web Application" from the list of templates.
Enter a name for your project and click "Create".

Understanding the Project Structure

An project is organized into several folders and files. The following are the most important folders and files:
App_Data: This folder is used to store application data, such as databases and configuration files.
App_Start: This folder contains files that are executed when the application starts.
Controllers: This folder contains classes that handle user requests and generate responses.
Models: This folder contains classes that represent data objects.
Views: This folder contains files that define the user interface of the application.

Building a Simple Application

Let's build a simple application that displays a "Hello World" message. Create a new project and add the following code to the file:```csharp
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
}
```

Next, create a new view file named and add the following code:```html
```

Run the application and you should see the "Hello World!" message displayed in the browser.

Passing Data to Views

In , you can pass data from controllers to views using the ViewData and ViewBag properties. To pass data using ViewData, use the following syntax:```csharp
ViewData["Message"] = "Hello World!";
```

To pass data using ViewBag, use the following syntax:```csharp
= "Hello World!";
```

In the view, you can access the data using the following syntax:```html

```

Handling User Input

provides several ways to handle user input, such as through forms, query strings, and route parameters. To create a form, use the following HTML:```html




```

In the controller, you can access the form data using the property. For example:```csharp
string name = ["name"];
```

Database Connectivity

supports connecting to various database systems, such as SQL Server, MySQL, and Oracle. To connect to a database, you need to add a connection string to the file. For example, for a SQL Server database:```xml



```

Once the connection string is added, you can use Entity Framework Core to interact with the database. For example, to get a list of all records from a table named "Customers":```csharp
using ;
public class HomeController : Controller
{
private readonly MyDbContext _context;
public HomeController(MyDbContext context)
{
_context = context;
}
public IActionResult Index()
{
var customers = ();
return View(customers);
}
}
```

Deploying an Application

Once you have developed and tested your application, you need to deploy it to a web server so that it can be accessed by users. There are several ways to deploy an application, such as using IIS, Docker, or Azure App Service.
