What is Asp.Net Core?

ASP.NET Core is a new version of ASP.NET, developed by Microsoft. It is an open-source framework for developing web application and it can be run on windows, Mac, or Linux. ASP.NET Core application can run on both .NET CORE and traditional .NET Framework (.NET framework 4.x). It is completely rewritten from scratch and it was initially launched as Asp.Net 5 but then was renamed to ASP.NET CORE 1.0. Latest version of Asp.Net Core is Asp.Net Core 7.0.

Asp.Net Core is a Cross platform, High-performance, Open-source framework for building modern, Cloud-based, internet-connected applications.

Why Use Asp.Net Core?

• Cross platform - It can run on windows, Linux and Mac.
• Better performance - Asp.net core does not depend on system.web.dll for communication between Browser-server. In Asp.net core everything is packages which we need for our application. Packages reduce the request pipeline and improve application performance.
• Dependency Injection - Dependency Injection is in-built in Asp.Net Core.
• Integration with Modern UI Frameworks - It supports modern UI like Angular, ReactJS and Bootstrap, etc.
• Hosting - Asp.Net Core application can be hosted on multiple Web server such as IIS, Apache, Docker, etc. It is not dependent on IIS.
• Open Source - It is fully open-source framework.
• Testability - Unit testing is very easy in Asp.Net core application.
• Side-by-side App Versioning - Asp.Net Core runs on .NET Core, which supports simultaneously running in multiple versions of applications.
• Unified Programming Model for MVC and Web API - In Asp.Net Core both MVC Controller and API Controller Inherit from the same controller base class.

Prerequisites

1. Install Visual Studio 2022 updated version 17.4.0
2. Install .NET SDK 7.0

Connect To Visual Studio 2022 Community Edition and Create Your First Project

Step 1

First, install Visual Studio 2022 in your system.

Step 2

Go to all programs in your systems, we can see Visual Studio 2022 and Visual Studio Installer.

Step 3

Double-click on Visual Studio 2022 and it will open. It looks like the below screenshot. Opening it the first time will take few minutes.

Creating Your First Project

Click on; create a new Project to create a new project.

You can see various project types there. Choose “Asp.Net Core Web Application” project type for now.

Select Asp.Net Core Web Application, and then click Next.

Give a valid name to your project and select a path for it. Then click Next button.

Now, Select framework .NET 7.0(Standard Term Support). You can select the Authentication Type as None, Individual Account, Microsoft Identity platform, or windows.

If you need Docker in your project then Select Enable Docker.

Uncheck Do not use top-level statements.

Then click the create button.

 Asp.Net Core 7.0 Web application created and project structure is shown below,

 Program.cs file looks like the below.

The Project.cspoj file looks like below. Where you can see the target Framework net7.0, by default Nullanle and ImplicitUsings are enabled.

Now, build and Press Ctrl+F5 to run without the debugger. I have made some minor changes to the view pages.

Visual Studio displays the following dialog: 

Select Yes if you trust the IIS Express SSL certificate.

Again, The following dialog is displayed:

Select Yes if you agree to trust the development certificate.

Conclusion

In this article, we explained the basics of ASP.NET core 7.0 and what’s new in Asp.NET Core 7.0. We also created a simple “AspDotNetCore7Demo” Asp.Net Core 7.0 web application and run.
