Visual Studio Code Tips and Tricks 'Tips and Tricks' lets you jump right in and learn how to be productive with Visual Studio Code. You'll become familiar with its powerful editing, code intelligence, and source code control features and learn useful keyboard shortcuts. For Visual Studio for Mac, see Source editor (Visual Studio for Mac). Regions in the outlining margin are also highlighted when you hover over the margin with the mouse. The default highlighting color may seem rather faint in some color configurations. Developer Community for Visual Studio Product family. Visual Studio. Visual Studio. Visual Studio. Visual Studio for Mac.NET. Azure DevOps. Outlining/Collapse to Definitions in C# does not properly collapse expression-bodied code. Windows 10.0 visual studio 2017 rc. Visual Studio Code is the first code editor, and first cross-platform development tool - supporting OSX, Linux, and Windows - in the Visual Studio family. At its heart, Visual Studio Code features a powerful, fast code editor great for day-to-day use.

We all are very much familiar with #region in Visual Studio that let us specify a block of code to categorized and allow to expand and collapse. With having a region name given, it is often easier to segregate the code module and keep on the code block which is required. While you can have defined regions for different code block, often for a larger files you many need to focus on specific set of code and you don’t want to have separate region name for them. In that case, you can just simply collapse them on the fly and use them as long as you need them.

Re: What are shortcuts for expand / collapse all regions in Visual Studio? When I write a code inside the region and collapse it.after to it If would be searching the some text which is inside the region its showing zero (0) results,it seems visual studio doesn't search text inside collapsed region.is there any trick to enable that search. To find other keyboard-related commands related to collapsing sections of code, in the Visual Studio menu bar click: Tools -> Options -> Environment -> Keyboard This will display the keyboard section in the Options dialog box. Visual Studio Code lets you perform most tasks directly from the keyboard. This page lists out the default bindings (keyboard shortcuts) and describes how you can update them. Note: If you visit this page on a Mac, you will see the key bindings for the Mac.

Here is the steps to follow:

• Select the section of code
• Press Ctrl+M+H – Turn on the collapsible/expandable option
• Press Ctrl+M+U – Turn off the the collapsible/expandable option.

Related Tip: Surround generated code with #region while implement Interface

• Here is how it looks like..

To remove the option you really don’t need to select the section back again. You can just place the cursor anywhere in the defined block and press the Ctrl+M+U option to remove the options.

This works well as similar to other collapsible panel in Visual Studio code editor. You can just move hover on it to get a preview of the content.

This is really interesting feature and can make your code navigation very easy and faster.

Hope this helps !

'Tips and Tricks' lets you jump right in and learn how to be productive with Visual Studio Code.

File associations

Create language associations for files that aren't detected correctly. For example, many configuration files with custom file extensions are actually JSON.

Preventing dirty writes

VS Code will show you an error message when you try to save a file that cannot be saved because it has changed on disk. VS Code blocks saving the file to prevent overwriting changes that have been made outside of the editor.

In order to resolve the save conflict, click the Compare action in the error message to open a diff editor that will show you the contents of the file on disk (to the left) compared to the contents in VS Code (on the right):

Use the actions in the editor toolbar to resolve the save conflict. You can either Accept your changes and thereby overwriting any changes on disk, or Revert to the version on disk. Reverting means that your changes will be lost.

Note: The file will remain dirty and cannot be saved until you pick one of the two actions to resolve the conflict.

Editing hacks

Here is a selection of common features for editing code. If the keyboard shortcuts aren't comfortable for you, consider installing a keymap extension for your old editor.

Tip: You can see recommended keymap extensions in the Extensions view with ⌘K ⌘M (Windows, Linux Ctrl+K Ctrl+M) which filters the search to @recommended:keymaps.

Multi cursor selection

To add cursors at arbitrary positions, select a position with your mouse and use Alt+Click (Option+click on macOS).

To set cursors above or below the current position use:

Keyboard Shortcut: ⌥⌘↑ (Windows Ctrl+Alt+Up, Linux Shift+Alt+Up) or ⌥⌘↓ (Windows Ctrl+Alt+Down, Linux Shift+Alt+Down)

You can add additional cursors to all occurrences of the current selection with ⇧⌘L (Windows, Linux Ctrl+Shift+L).

Note: You can also change the modifier to Ctrl/Cmd for applying multiple cursors with the editor.multiCursorModifiersetting . See Multi-cursor Modifier for details.

If you do not want to add all occurrences of the current selection, you can use ⌘D (Windows, Linux Ctrl+D) instead. This only selects the next occurrence after the one you selected so you can add selections one by one.

Column (box) selection

You can select blocks of text by holding Shift+Alt (Shift+Option on macOS) while you drag your mouse. A separate cursor will be added to the end of each selected line.

You can also use keyboard shortcuts to trigger column selection.

Fast scrolling

Pressing the Alt key enables fast scrolling in the editor and Explorers. By default, fast scrolling uses a 5X speed multiplier but you can control the multiplier with the Editor: Fast Scroll Sensitivity (editor.fastScrollSensitivity) setting.

Copy line up / down

Keyboard Shortcut: ⇧⌥↑ (Windows Shift+Alt+Up, Linux Ctrl+Shift+Alt+Up) or ⇧⌥↓ (Windows Shift+Alt+Down, Linux Ctrl+Shift+Alt+Down)

The commands Copy Line Up/Down are unbound on Linux because the VS Code default keybindings would conflict with Ubuntu keybindings, see Issue #509. You can still set the commands editor.action.copyLinesUpAction and editor.action.copyLinesDownAction to your own preferred keyboard shortcuts.

Move line up and down

Keyboard Shortcut: ⌥↑ (Windows, Linux Alt+Up) or ⌥↓ (Windows, Linux Alt+Down)

Debugging

Configure debugger

Open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and select Debug: Open launch.json, which will prompt you to select the environment that matches your project (Node.js, Python, C++, etc). This will generate a launch.json file. Node.js support is built-in and other environments require installing the appropriate language extensions. See the debugging documentation for more details.

Breakpoints and stepping through

Place breakpoints next to the line number. Navigate forward with the Debug widget.

Data inspection

Inspect variables in the Debug panels and in the console.

Inline values

You can set 'debug.inlineValues': true to see variable values inline in the debugger. This feature can be expensive and may slow down stepping, so it is disabled by default.

Task runner

Auto detect tasks

Select Terminal from the top-level menu, run the command Configure Tasks, then select the type of task you'd like to run. This will generate a tasks.json file with content like the following. See the Tasks documentation for more details.

Visual Studio Code For Mac

There are occasionally issues with auto generation. Check out the documentation for getting things to work properly.

Run tasks from the Terminal menu

Select Terminal from the top-level menu, run the command Run Task, and select the task you want to run. Terminate the running task by running the command Terminate Task

Define keyboard shortcuts for tasks

You can define a keyboard shortcut for any task. From the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)), select Preferences: Open Keyboard Shortcuts File, bind the desired shortcut to the workbench.action.tasks.runTask command, and define the Task as args.

For example, to bind Ctrl+H to the Run tests task, add the following:

Run npm scripts as tasks from the explorer

With the setting npm.enableScriptExplorer, you can enable an explorer that shows the scripts defined in your workspace.

From the explorer you can open a script in the editor, run it as a task, and launch it with the node debugger (when the script defines a debug option like --inspect-brk). The default action on click is to open the script. To run a script on a single click, set npm.scriptExplorerAction to 'run'. Use the setting npm.exclude to exclude scripts in package.json files contained in particular folders.

Portable mode

VS Code has a Portable mode which lets you keep settings and data in the same location as your installation, for example, on a USB drive.
