Tutorial: ASP.NET Core First Console Application

Steps 1 ASP.NET Core — Environment Setup

To use ASP.NET Core in your application, the following must be installed in your system:

• Microsoft Visual Studio 2019 Community (Download VS2019)

• .NET Core 3.1 SDK (Download .Net Core3.1)

Step 2 New Project

Once you have installed the Visual Studio 2019, you can start building a new ASP.NET Core Console Application.

• Open VS2019

• On the start page, choose Create a new project.

• On the Create a New Project dialog box, you will see the following different templates for Web projects. Now select the Console App (.NET Core) template with C#:

• In the Configure your new project dialog, enter HelloWorldConsoleApp in the Project name box and select you location where it will save. Then choose Create.

• Now, you can see your new project is created and opened.

Step 3 Run Project

• Let us run this application, you can do that by pressing Ctrl+F5 or Click on Play button on top.

Reference Code:

static void Main(string[] args)

{

Console.WriteLine(“Hello World!”);

}

• A console window opens with the text “Hello World!” printed on the screen and some Visual Studio debug information.

• Press any key to close the console window.

Step 4 Enhance the application

Enhance the application to prompt the name which you entered and display it along with the date and time.

• Console.WriteLine is use for output and Console.ReadLine is use for input. So let’s use both combination and Enhance our app.
• In Program.cs replace the contents of the Main method, which is the line that calls Console.WriteLine, with the following code:

Reference Code:

static void Main(string[] args)

{

Console.WriteLine(“Hello!”);

Console.WriteLine(“\nWho are you there?”);

Console.WriteLine(“\nwaiting…for your good name.”);

var name = Console.ReadLine();

var date = DateTime.Now;

Console.WriteLine($”\nHello, {name}, on {date:d} at {date:t}!”);

Console.Write(“\nPress any key to exit…”);

Console.ReadKey(true);

}

• Now, Again Run Application by pressing Ctrl+F5 or Click on Play button on top.

• Respond to the prompt by entering a name and pressing the Enter key.
• Press any key to close the console window.
