.NET ASP.NET Core

Introduction to ASP.NET Core

ASP.NET Core is a free, open-source, and cross-platform framework for building modern, cloud-based, Internet-connected applications. It is a redesign of the ASP.NET framework that is optimized for high-performance and scalability. With ASP.NET Core, developers can build web applications, IoT applications, and microservices. This framework is known for its ability to host applications on Windows, macOS, and Linux, making it versatile for developers.

ASP.NET Core MVC Architecture

ASP.NET Core MVC is a rich framework for building web apps and APIs using the Model-View-Controller (MVC) design pattern. It provides a clean separation of concerns, enabling you to organize and manage your code efficiently. The MVC pattern helps in dividing the application into three core components:

• Model: Represents the application's data and business logic.
• View: Responsible for displaying the user interface.
• Controller: Handles user input and interactions, and updates the Model and View accordingly.

Creating a New ASP.NET Core MVC Project

To create a new ASP.NET Core MVC project, you can use the .NET CLI or Visual Studio. Below is an example of how to create a new project using the .NET CLI:

This command creates a new directory called MyMvcApp with a basic MVC structure. You can then navigate into this directory and run the application.

Understanding Razor in ASP.NET Core

Razor is a markup syntax that allows you to embed server-based code into web pages. It is a key component of ASP.NET Core MVC for generating dynamic content. Razor syntax is clean and concise, making it easy to write HTML with C# code.

Here is a simple example of using Razor in a view:

In this example, a C# variable is declared and used within an HTML element. Razor handles the server-side execution to render the final HTML output.

Deploying ASP.NET Core Applications

Once you have developed your ASP.NET Core application, it's time to deploy it. ASP.NET Core apps can be deployed to various environments, including on-premises servers, cloud platforms like Microsoft Azure, and container orchestration platforms such as Docker and Kubernetes.

Deployment involves publishing the app to a target environment where it can be accessed by users. This process typically includes configuring the hosting environment, setting up databases, and managing app settings specific to the production environment.

ASP.NET Core provides a wide range of tools and services to help with deployment, including integration with popular CI/CD pipelines.
