Creating ASP.NET Core 3.1 Web Application using Visual Studio
In this article, I am going to discuss How to Create the ASP.NET Core Web Application step by step from scratch using Visual Studio 2019 and ASP.NET Core 3.1. Please, read our previous article before proceeding to this article, where we discussed ASP.NET Core Environment Setup. In this article, I am going to use Visual Studio 2019 and ASP.NET Framework 3.1.
Creating the First ASP.NET Core Web Application using Visual Studio 2019 and ASP.NET Core 3.1
To create a new ASP.NET Core Project using ASP.NET Core 3.1, open Visual Studio 2019. And then click on the Create a new project box as shown in the below image.
Once you click on the Create a new project box, it will open the “Create a new project” window. This window includes different .NET Core 3.1 application templates. Here we will create a simple web application, so select the ASP.NET Core Web Application template and click on the Next button as shown in the below image.
Once you click on the Next button, it will open the following Configure Your New Project window. Here, you need to give an appropriate name for your project, set the location where you want to create this project, and the solution name for the ASP.NET Core Web application. In this example, we will give the name “FirstCoreWebApplication” and click on the Create button, as shown in the image below.
Once you click on the Create button, it will open the Create a new ASP.NET Core Web Application as shown below. Here, you need to select the appropriate ASP.NET Core Web application template such as Empty, API, Web Application, Web Application (MVC), Angular, etc. Here in this demo, we are going to use the Empty template so that you will understand how the different components fit together to develop an ASP.NET Core application. Also, make sure that you have selected the appropriate .NET Core and ASP.NET Core versions (latest 3.1). Make sure to uncheck all the checkboxes from the Advanced section and finally click on the Create button, as shown in the below image.
Once you click on the Create button, it will create a new ASP.NET Core Web Application in Visual Studio 2019 using ASP.NET Core 3.1 Framework. Wait for some time till Visual Studio restores the packages in the project. The restoring process means Visual Studio will automatically add, update or delete configured dependencies as NuGet packages in the project. The project will be created with the following file and folder structure in Visual Studio 2019.
Run the ASP.NET Core Application:
To run this web application, click on IIS Express or press F5 (with Debug) or Ctrl + F5 (without Debug). This will open the browser and display the following output.
Here, the output “Hello World!” comes from the Configure method of the Startup class, which is present inside the Startup.cs file Open Startup.cs file and then change the “Hello World!” string to something else and rerun the application, and it will change the output accordingly.
In the next article, I am going to discuss How to Create ASP.NET Core Web Application using Visual Studio 2022 and .NET 6. In this article, I explain How to Create the ASP.NET Core Web Application using Visual Studio step by step using the different types of templates from scratch. I would like to have your feedback. Please post your feedback, question, or comments about this article.
