VS Code does not expose the DOM as part of the API. Instead this extension relies on using TextEditorDecorations to set css properties for ranges in the editor. This has a few limitations: The cursor doesn't move with the text as it shakes. So, as usual, I'm late to the party! This time the party is VS Code and it's pretty fun okay. Instead of just playing around with JavaScript or HTML, I thought why not see if I can write Visual Basic code and send it to the compiler. VS Code also integrates with tooling and frameworks such as Maven, Tomcat, Jetty, and Spring Boot. Leveraging the power of Visual Studio Code, Java developers get an excellent tool for both quick code editing and also the full debugging and testing cycle.

In this tutorial for Visual Basic (VB), you'll use Visual Studio to create and run a few different console apps and explore some features of the Visual Studio integrated development environment (IDE) while you do so.

If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.

Create a project

First, we'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!

  1. Open Visual Studio 2017.

  2. From the top menu bar, choose File > New > Project.

  3. 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 WhatIsYourName.

Add a workload (optional)

If you don't see the Console App (.NET Core) project template, you can get it by adding the .NET Core cross-platform development workload. You can add this workload in one of the two following ways, depending on which Visual Studio 2017 updates are installed on your machine.

Option 1: Use the New Project dialog box

  1. Click the Open Visual Studio Installer link in the left pane of the New Project dialog box.

  2. The Visual Studio Installer launches. Choose the .NET Core cross-platform development workload, and then choose Modify.

Option 2: Use the Tools menu bar

  1. Cancel out of the New Project dialog box and from the top menu bar, choose Tools > Get Tools and Features.

  2. The Visual Studio Installer launches. Choose the .NET Core cross-platform development workload, and then choose Modify.

Note

Some of the screenshots in this tutorial use the dark theme. If you aren't using the dark theme but would like to, see the Personalize the Visual Studio IDE and Editor page to learn how.

  1. Open Visual Studio 2019.

  2. On the start window, choose Create a new project.

  3. In the Create a new project window, choose Visual Basic from the Language list. Next, choose Windows from the Platform list and Console from the project types list.

    After you apply the language, platform, and project type filters, choose the Console Application template, and then choose Next.

    Note

    If you do not see the Console Application template, you can install it from the Create a new project window. In the Not finding what you're looking for? message, choose the Install more tools and features link.

    Then, in the Visual Studio Installer, choose the .NET Core cross-platform development workload.

    After that, choose the Modify button in the Visual Studio Installer. You might be prompted to save your work; if so, do so. Next, choose Continue to install the workload. Then, return to step 2 in this 'Create a project' procedure.

  4. In the Configure your new project window, type or enter WhatIsYourName in the Project name box. Then, choose Next.

  5. In the Additional information window, .NET Core 3.1 should already be selected for your target framework. If not, select .NET Core 3.1. Then, choose Create.

    Visual Studio opens your new project.

Create a 'What Is Your Name' application

Let's create an app that prompts you for your name and then displays it along with the date and time. Here's how:

  1. If it is not already open, then open your WhatIsYourName project.

  2. Enter the following Visual Basic code immediately after the opening bracket that follows the Sub Main(args As String()) line and before the End Sub line:

    This code replaces the existing WriteLine, Write, and ReadKey statements.

  3. Use the green Start button, or press F5 to build and run your first app.

  4. When the console window opens, enter your name. Your console window should look similar to the following screenshot:

  5. Press any key to close the console window.

  1. In the WhatIsYourName project, enter the following Visual Basic code immediately after the opening bracket that follows the Sub Main(args As String()) line and before the End Sub line:

    This code replaces the existing WriteLine, Write, and ReadKey statements.

  2. Use the green Start button, or press F5 to build and run your first app.

  3. When the console window opens, enter your name. Your console window should look similar to the following screenshot:

  4. Press any key to close the console window.

Create a 'Calculate This' application

  1. Open Visual Studio 2017, and then from the top menu bar, choose File > New > Project.

  2. 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 file CalculateThis.

  3. Enter the following code between the Module Program line and End Module line:

    Your code window should look like the following screenshot:

  4. Click CalculateThis to run your program. Your console window should look similar to the following screenshot:

  1. On the start window, choose Create a new project.

  2. In the Create a new project window, choose Visual Basic from the Language list. Next, choose Windows from the Platform list and Console from the project types list.

  3. After you apply the language, platform, and project type filters, choose the Console Application template, and then choose Next.

    Then, in the Configure your new project window, type or enter CalculateThis in the Project name box. Then, choose Next.

  4. In the Additional information window, .NET Core 3.1 should already be selected for your target framework. If not, select .NET Core 3.1. Then, choose Create.

  5. Enter the following code between the Module Program line and End Module line:

    Your code window should look like the following screenshot:

Quick answers FAQ

Here's a quick FAQ to highlight some key concepts.

Visual Studio Code Full Download

What is Visual Basic?

Visual Basic is a type-safe programming language that's designed to be easy to learn. It is derived from BASIC, which means 'Beginner's All-purpose Symbolic Instruction Code'.

What is Visual Studio?

Hard drive test for mac. Visual Studio is an integrated development suite of productivity tools for developers. Think of it as a program you can use to create programs and applications.

What is a console app?

A console app takes input and displays output in a command-line window, also known as a console.

What is .NET Core?

.NET Core is the evolutionary next step of the .NET Framework. Where the .NET Framework allowed you to share code across programming languages, .NET Core adds the ability to share code across platforms. Even better, it's open source. (Both the .NET Framework and .NET Core include libraries of prebuilt functionality as well as a common language runtime (CLR), which acts as a virtual machine in which to run your code.)

Support for Java in Visual Studio Code is provided through a wide range of extensions. Combined with the power of core VS Code, these extensions give you a lightweight and performant code editor that also supports many of the most common Java development techniques.

This article will give you an overview of different capabilities of Visual Studio Code for Java developers. For a quick walkthrough of editing, running, and debugging a Java program with Visual Studio Code, use the button below.

Overview

VS Code provides essential language features such as code completion, refactoring, linting, formatting, and code snippets along with convenient debugging and unit test support. VS Code also integrates with tooling and frameworks such as Maven, Tomcat, Jetty, and Spring Boot. Leveraging the power of Visual Studio Code, Java developers get an excellent tool for both quick code editing and also the full debugging and testing cycle. It's a great choice for your Java work if you're looking for a tool which:

  • Is fast, lightweight, free, and open source.
  • Supports many other languages, not just Java.
  • Helps start your Java journey without installing and learning a complex IDE.
  • Provides great microservices support including popular frameworks, container tooling, and cloud integration.
  • Offers team-based collaboration features such as Visual Studio Live Share.
  • Improves your productivity through IntelliSense and other code-aware editing features.

Install Visual Studio Code for Java

To help you set up quickly, we recommend you use the Coding Pack for Java, which is the bundle of VS Code, the Java Development Kit (JDK), and a collection of suggested extensions by Microsoft. The Coding Pack can also be used to fix an existing development environment.

Install the Coding Pack for Java - macOS

Note: The Coding Pack for Java is only available for Windows and macOS. For other operating systems, you will need to manually install a JDK, VS Code, and Java extensions.

If you have already installed VS Code and want to add Java support to it, we recommend to use Java Extension Pack, a collection of extensions suggested by Microsoft:

Alternatively, you can add Java language support to VS Code by installing the popular Java extensions by yourself.

Download VS Code - If you haven't downloaded VS Code yet, quickly install for your platform (Windows, macOS, Linux).

There are also other popular Java extensions you can pick for your own needs, including:

Thanks to the great Java community around VS Code, the list doesn't end there. You can search for more Java extensions easily within VS Code:

  1. Go to the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)).
  2. Filter the extensions list by typing 'java'.

This document describes some of the key features included in those Java extensions.

Getting started

Vscode Visual Basic 2020

NOTE: If you are using VS Code on Windows and want to take advantage of the Windows Subsystem for Linux, see Developing in WSL.

Before you start, you must have the Java SE Development Kit (JDK) on your local environment. To run the VS Code for Java extension, Java SE 11 or above version is required; for projects, VS Code for Java supports projects with version 1.5 or above. For how to configure, refer to Configure JDK.

For developers new to Java or new to VS Code, we provide a Getting Started experience. Once you've installed the Java Extension Pack, you can open the Getting Started experience from within VS Code with the Java: Getting Started command from the Command Palette. Open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and type 'Java: Getting Started'.

Working with Java source files

Vscode Visual Basic Tutorial

You can use VS Code to read, write, run, and debug Java source file(s) without creating a project. VS Code for Java supports two modes, lightweight and standard. Lightweight mode is ideal for scenarios that only deal with source file(s). If you want to work with a full scale project, standard mode will be required. You can easily switch from lightweight mode to standard mode, when needed. To learn more, see Lightweight Mode.

Working with Java project

There are three things you must understand to work with Java in VS Code:

  1. How does VS Code handle Workspaces?
  2. How does VS Code handle Java?
  3. How does VS Code handle Workspaces that contain Java?

VS Code Workspaces

In Visual Studio Code, a 'Workspace' means a collection of one or more filesystem folders (and their children) and all of the VS Code configurations that take effect when that 'Workspace' is open in VS Code. There are two kinds of 'Workspaces' in VS Code, 'folder workspaces' and 'multi-root workspaces'.

A 'folder workspace' is presented by VS Code when you open a filesystem folder (directory) in VS Code.

A 'multi-root workspace' can refer to multiple folders (directories) from disparate parts of the file system and VS Code displays the contents of the folder(s) of the workspace together in the File Explorer. To learn more, see Multi-root Workspaces.

Java project in VS Code

In contrast to IDEs such as IntelliJ IDEA, NetBeans, or Eclipse, the concept of a 'Java project' is provided entirely by extensions, and is not a core concept in the base VS Code. When working with 'Java projects' in VS Code, you must have the necessary extensions installed to work with those project files.

For example, Maven, Eclipse, and Gradle Java projects are supported through Language Support for Java(TM) by Red Hat, by utilizing M2Eclipse, which provides Maven support, and Buildship, which provides Gradle support through the Eclipse JDT Language Server.

With Maven for Java, you can generate projects from Maven Archetypes, browse through all the Maven projects within your workspace, and execute Maven goals easily from an embedded explorer. Projects can also be created and managed with the Project Manager for Java extension.

Visual Studio Code also supports working with standalone Java files outside of a Java project, described in the Java Tutorial with VS Code.

VS Code Workspaces that contain Java project

Assuming the necessary Java extensions are installed, opening a VS Code workspace that contains Java artifacts will cause those extensions to understand those artifacts and present options for working with them.

More details about Java project support can be found in Java Project Management in Visual Studio Code and Build Tools.

Editing

Code Navigation

Java in Visual Studio Code also supports source code navigation features such as search for symbol, Peek Definition, and Go to Definition. The Spring Boot Tools extension provides enhanced navigation and code completion support for Spring Boot projects.

One of the key advantages of VS Code is speed. When you open your Java source file or folder, within a few seconds, with the help of Lightweight Mode, you will be able to navigate your code base with Outline view as well as commands such as Go to Definition and Go to Reference. This is especially useful when you open a project for the first time.

Code Completion

IntelliSense is a general term for language features, including intelligent code completion (in-context method and variable suggestions) across all your files and for built-in and third-party modules. VS Code supports code completion and IntelliSense for Java through Language Support for Java(TM) by Red Hat. It also provides AI-assisted IntelliSense called IntelliCode by putting what you're most likely to use at the top of your completion list.

See also in Java Code Navigation and Editing. VS Code also supports a range of Refactoring and Linting features.

Debugging

Debugger for Java is a lightweight Java Debugger based on Java Debug Server. It works with Language Support for Java by Red Hat to allow users to debug Java code within Visual Studio Code.

Starting a debugging session is easy, click on the Run|Debug button available at the CodeLens of your main() function, or press F5. The debugger will automatically generate the proper configuration for you.

Although it's lightweight, the Java debugger supports advanced features such as expression evaluation, conditional breakpoints, and hot code replacement. For more debugging related information, visit Java Debugging.

Testing

With the support from the Java Test Runner extension, you can easily run, debug, and manage your JUnit and TestNG test cases.

For more about testing, read Testing Java.

Spring Boot, Tomcat, and Jetty

To further improve your Java productivity in VS Code, there are extensions for most popular frameworks and tools such as Spring Boot, Tomcat, and Jetty created by the community.

The Tomcat extension includes an explorer to easily navigate and manage your Tomcat servers. You can create, start, debug, stop, and rename your Tomcat server with the extension.
