Features of the code editor

The Visual Studio editor provides many features that make it easier for you to write and manage your code and text. You can expand and collapse different blocks of code by using outlining. You can learn more about the code by using IntelliSense, the Object Browser, and the Call Hierarchy. You can find code by using features such as Go To, Go To Definition, and Find All References. You can insert blocks of code with code snippets, and you can generate code by using features such as Generate From Usage. If you have never used the Visual Studio editor before, see Learn to use the code editor.

This topic applies to Visual Studio on Windows. For Visual Studio for Mac, see Source editor (Visual Studio for Mac).

You can view your code in a number of different ways. By default, Solution Explorer shows your code organized by files. You can click on the Class View tab at the bottom of the window to view your code organized by classes.

You can search and replace text in single or multiple files. For more information, see Find and replace text. You can use regular expressions to find and replace text. For more information, see Use regular expressions in Visual Studio.

The different Visual Studio languages offer different sets of features, and in some cases the features behave differently in different languages. Many of these differences are specified in the descriptions of the features, but for more information you can see the sections on specific Visual Studio languages.

Editor features

Feature Description
Syntax Coloring Some syntax elements of code and markup files are colored differently to distinguish them. For example, keywords (such as using in C# and Imports in Visual Basic) are one color, but types (such as Console and Uri ) are another color. Other syntax elements are also colorized, such as string literals and comments. C++ uses color to differentiate among types, enumerations, and macros, among other tokens.

You can see the default color for each type, and you can change the color for any specific syntax element in the Fonts and Colors, Environment, Options dialog box, which you can open from the Tools menu. Error and Warning Marks As you add code and build your solution, you may see (a) different-colored wavy underlines (known as squiggles) or (b) light bulbs appearing in your code. Red squiggles denote syntax errors, blue denotes compiler errors, green denotes warnings, and purple denotes other types of errors. Quick Actions suggest fixes for problems and make it easy to apply the fix.

You can see the default color for each error and warning squiggle in the Tools > Options > Environment > Fonts and Colors dialog box. Look for Syntax Error, Compiler Error, Warning, and Other Error. Brace Matching When the insertion point is placed on an open brace in a code file, both it and the closing brace are highlighted. This feature gives you immediate feedback on misplaced or missing braces. You can turn brace matching on or off with the Automatic Delimiter Highlighting setting (Tools > Options > Text Editor). You can change the highlight color in the Fonts and Colors setting (Tools > Options > Environment). Look for Brace Matching (Highlight) or Brace Matching (Rectangle). Structure Visualizer Dotted lines connect matching braces in code files, making it easier to see opening and closing brace pairs. This can help you find code in your codebase more quickly. You can turn these lines on or off with the Show structure guidelines in the Display section of the Tools > Options > Text Editor > General page. Line Numbers Line numbers can be displayed in the left margin of the code window. They are not displayed by default. You can turn this option on in the Text Editor All Languages settings (Tools > Options > Text Editor > All Languages). You can display line numbers for individual programming languages by changing the settings for those languages (Tools > Options > Text Editor > ). For line numbers to print, you must select Include line numbers in the Print dialog box. Change Tracking The color of the left margin allows you to keep track of the changes you have made in a file. Changes you have made since the file was opened but not saved are denoted by a yellow bar on the left margin (known as the selection margin). After you have saved the changes (but before closing the file), the bar turns green. If you undo a change after you have saved the file, the bar turns orange. To turn this feature off and on, change the Track changes option in the Text Editor settings (Tools > Options > Text Editor). Selecting Code and Text You can select text either in the standard continuous stream mode or in box mode, in which you select a rectangular portion of text instead of a set of lines. To make a selection in box mode, press Alt as you drag the mouse over the selection (or press Alt+Shift+ ). The selection includes all of the characters within the rectangle defined by the first character and the last character in the selection. Anything typed or pasted into the selected area is inserted at the same point on each line. Zoom You can zoom in or out in any code window by pressing and holding the Ctrl key and moving the scroll wheel on the mouse (or Ctrl+Shift+. to increase and Ctrl+Shift+, to decrease). You can also use the Zoom box in the lower left corner of the code window to set a specific zoom percentage. The zoom feature does not work in tool windows. Virtual Space By default, lines in Visual Studio editors end after the last character, so that the Right Arrow key at the end of a line moves the cursor to the beginning of the next line. In some other editors a line does not end after the last character, and you can place your cursor anywhere on the line. You can enable virtual space in the editor in the Tools > Options > Text Editor > All Languages settings. Note that you can enable either Virtual Space or Word Wrap, but not both. Printing You can use the options in the Print dialog box to include line numbers or hide collapsed regions of code when you print a file. In the Page Setup dialog box, you can also choose to print the full path and the name of the file by choosing Page header.

You can set color printing options in the Tools > Options > Environment > Fonts and Colors dialog box. Choose Printer in the Show settings for list to customize color printing. You can specify different colors for printing a file than for editing a file. Global Undo and Redo The Undo Last Global Action and Redo Last Global Action commands on the Edit menu undo or redo global actions that affect multiple files. Global actions include renaming a class or namespace, performing a find-and-replace operation across a solution, refactoring a database, or any other action that changes multiple files. You can apply the global undo and redo commands to actions in the current Visual Studio session, even after you close the solution in which an action was applied.

Advanced editing features

You can find a number of advanced features on the Edit > Advanced menu on the toolbar. Not all of these features are available for all types of code files.

Feature Description
Format Document Sets the proper indentation of lines of code and moves curly braces to separate lines in the document.
Format Selection Sets the proper indentation of lines of code and moves curly braces to separate lines in the selection.
Tabify Selected Lines Changes leading spaces to tabs where appropriate.
Untabify Selected Lines Changes leading tabs to spaces. If you want to convert all the spaces in your file to tabs (or all the tabs to spaces), you can use the Edit.ConvertSpacesToTabs and Edit.ConvertTabsToSpaces commands. These commands do not appear in Visual Studio menus, but you can call them from the Quick Access window or the command window.
Make Uppercase Changes all characters in the selection to uppercase, or if there is no selection, changes the character at the insertion point to uppercase. Shortcut: Ctrl+Shift+U.
Make Lowercase Changes all characters in the selection to lowercase, or if there is no selection, changes the character at the insertion point to lowercase. Shortcut: Ctrl+U.
Move selected Lines Up Moves the selected line up one line. Shortcut: Alt+Up Arrow.
Move Selected Lines Down Moves the selected line down one line. Shortcut: Alt+Down Arrow.
Delete Horizontal White Space Deletes tabs or spaces at the end of the current line. Shortcut: Ctrl+K, Ctrl+\
View White Space Displays spaces as raised dots, and tabs as arrows. The end of a file is displayed as a rectangular glyph. If Tools > Options > Text Editor > All Languages > Word Wrap > Show visible glyphs for word wrap is selected, that glyph is also displayed.
Word Wrap Causes all the lines in a document to be visible in the code window. You can turn word wrap off and on in the Text Editor All Languages settings (Tools > Options > Text Editor > All Languages).
Comment Selection Adds comment characters to the selection or the current line. Shortcut: Ctrl+K, Ctrl+C
Uncomment Selection Removes comment characters from the selection or the current line. Shortcut: Ctrl+K, Ctrl+U
Increase Line Indent Adds a tab (or the equivalent spaces) to the selected lines or the current line.
Decrease Line Indent Removes a tab (or the equivalent spaces) from the selected lines or the current line.
Select Tag In a document that contains tags (for example, XML or HTML), selects the tag.
Select Tag Content In a document that contains tags (for example, XML or HTML), selects the content.

You can move around in the code editor in several different ways, including navigating backwards and forwards to previous insertion points, viewing the definition of a type or member, and jumping to a specific method using the navigation bar. For more information see Navigate code.

Find references in your code base

To find where particular code elements are referenced throughout your codebase, you can use the Find All References command or press Shift+F12. Also, when you click on a type or member, the reference highlighting feature automatically highlights all references to that type or member. For more information, see Find references in your code.

Customize the editor

You can share your Visual Studio settings with another developer, have your settings conform to a standard, or return to Visual Studio default settings by using the Import and Export Settings Wizard command on the Tools menu. In the Import and Export Settings Wizard, you can change selected general settings or language and project-specific settings.

To define new hotkeys or redefine existing hotkeys, go to Tools > Options > Environment > Keyboard. For more information about hotkeys, see Default keyboard shortcuts.

For JavaScript-specific editor options, see JavaScript editor options.

Visual Studio Code on Windows

Installation

  1. Download the Visual Studio Code installer for Windows.
  2. Once it is downloaded, run the installer (VSCodeUserSetup-.exe). This will only take a minute.
  3. By default, VS Code is installed under C:\users\\AppData\Local\Programs\Microsoft VS Code .

Alternatively, you can also download a Zip archive, extract it and run Code from there.

Note: .NET Framework 4.5.2 or higher is required for VS Code. If you are using Windows 7, make sure you have at least .NET Framework 4.5.2 installed. You can check your version of .NET Framework using this command, reg query «HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\full» /v version from a command prompt.

Tip: Setup will add Visual Studio Code to your %PATH% , so from the console you can type ‘code .’ to open VS Code on that folder. You will need to restart your console after the installation for the change to the %PATH% environmental variable to take effect.

User versus system setup

VS Code provides both Windows user and system level setups. Installing the user setup does not require Administrator privileges as the location will be under your user Local AppData (LOCALAPPDATA) folder. User setup also provides a smoother background update experience.

The system setup requires elevation to Administrator privileges and will place the installation under Program Files.

See the Download Visual Studio Code page for a complete list of available installation options.

32-bit versions

If you need to run a 32-bit version of VS Code, both a 32-bit Installer and Zip archive are available.

Updates

VS Code ships monthly releases and supports auto-update when a new release is available. If you’re prompted by VS Code, accept the newest update and it will be installed (you won’t need to do anything else to get the latest bits).

Note: You can disable auto-update if you prefer to update VS Code on your own schedule.

Windows as a developer machine

Windows is a popular operating system and it can be a great cross-platform development environment. This section describes cross-platform features such as the Windows Subsystem for Linux (WSL) and the new Windows Terminal.

Recent Windows build

Make sure you are on a recent Windows 10 build. Check Settings > Windows Update to see if you are up-to-date.

Windows Subsystem for Linux

With WSL, you can install and run Linux distributions on Windows. This enables you to develop and test your source code on Linux while still working locally on your Windows machine.

When coupled with the Remote — WSL extension, you get full VS Code editing and debugging support while running in the context of WSL.

See the Developing in WSL documentation to learn more or try the Working in WSL introductory tutorial.

New Windows Terminal

Available from the Microsoft Store, the Windows Terminal (Preview) lets you easily open PowerShell, Command Prompt, and WSL terminals in a multiple tab shell.

Common questions

What command-line arguments are supported by the Windows Setup?

VS Code uses Inno Setup to create its setup package for Windows. Thus, all the Inno Setup command-line switches are available for use.

Additionally, you can prevent the Setup from launching VS Code after completion with /mergetasks=!runcode .

Scrolling is laggy and not smooth

On certain devices, editor scrolling is not smooth but laggy for an unpleasant experience. If you notice this issue, make sure you install the Windows 10 October 2018 update where this issue is fixed.

I’m having trouble with the installer

Try using the zip file instead of the installer. To use this, unzip VS Code in your AppData\Local\Programs folder.

Note: When VS Code is installed via a Zip file, you will need to manually update it for each release.

Icons are missing

I installed Visual Studio Code on my Windows 7 or 8 machine. Why are some icons not appearing in the workbench and editor?

VS Code uses SVG icons and we have found instances where the .SVG file extension is associated with something other than image/svg+xml . We’re considering options to fix it, but for now here’s a workaround:

Using the Command Prompt:

  1. Open an Administrator Command Prompt.
  2. Type REG ADD HKCR\.svg /f /v «Content Type» /t REG_SZ /d image/svg+xml .

Using the Registry Editor (regedit):

  1. Start regedit .
  2. Open the HKEY_CLASSES_ROOT key.
  3. Find the .svg key.
  4. Set its Content Type Data value to image/svg+xml .
  5. Exit regedit .
