Quickstart: Create your first console app in Visual Studio with Visual Basic
In this 5-10 minute introduction to the Visual Studio integrated development environment (IDE), you'll create a simple Visual Basic application that runs on the console.
If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.
Create a project
First, you'll create a Visual Basic application project. The project type comes with all the template files you'll need, before you've even added anything!
Open Visual Studio 2017.
From the top menu bar, choose File > New > Project.
In the New Project dialog box in the left pane, expand Visual Basic, and then choose .NET Core. In the middle pane, choose Console App (.NET Core). Then name the project HelloWorld.
If you don't see the Console App (.NET Core) project template, click the Open Visual Studio Installer link in the left pane of the New Project dialog box.
The Visual Studio Installer launches. Choose the .NET Core cross-platform development workload, and then choose Modify.
Create the application
After you select your Visual Basic project template and name your project, Visual Studio creates a simple "Hello World" application for you. It calls the WriteLine method to display the literal string "Hello World!" in the console window.
If you click the HelloWorld button in the IDE, you can run the program in Debug mode.
When you do this, the console window is visible for only a moment before it closes. This happens because the
Main method terminates after its single statement executes, and so the application ends.
Add some code
Let's add some code to pause the application and then ask for user input.
Add the following code immediately after the call to the WriteLine method:
Console.Write("Press any key to continue...") Console.ReadKey(true)
This pauses the program until you press a key.
On the menu bar, select Build > Build Solution.
This compiles your program into an intermediate language (IL) that's converted into binary code by a just-in-time (JIT) compiler.
Run the application
Click the HelloWorld button on the toolbar.
Press any key to close the console window.
