Go in Visual Studio Code. Using the Go extension for Visual Studio Code, you get features like IntelliSense, code navigation, symbol search, testing, debugging, and many more that will help you in Go development. You can install the Go extension from the VS Code Marketplace. Watch 'Getting started with VS Code Go' for an explanation of how to build your first Go application using VS Code Go. 1) If your project is created by other previous vs version, please close VS Instance, delete.vs hidden folder, bin, obj folder, then restart your project. Besides, try to create a new empty project and test whether this still happens. 2) delete any vs component caches under C:UsersxxxxAppDataLocalMicrosoftVisualStudio16.0xxxx. The Python extension provides many features for editing Python source code in Visual Studio Code: Autocomplete and IntelliSense; Quick Fixes; Run Selection/Line in Terminal (REPL) Formatting; Refactoring; Also see Linting and Jupyter Support. Autocomplete and IntelliSense. Autocomplete and IntelliSense are provided for all files within the. Visual Studio Code is a lightweight but powerful source code editor which runs on your desktop and is available for Windows, macOS and Linux. It comes with built-in support for JavaScript, TypeScript and Node.js and has a rich ecosystem of extensions for other languages (such as C, C#, Java, Python, PHP, Go) and runtimes (such as.NET and Unity). Visual Studio Code includes built-in JavaScript IntelliSense, debugging, formatting, code navigation, refactorings, and many other advanced language features. Most of these features just work out of the box, while some may require basic configuration to get the best experience. This page summarizes the JavaScript features that VS Code ships with.
IntelliSense is a code-completion aid that includes a number of features: List Members, Parameter Info, Quick Info, and Complete Word. These features help you to learn more about the code you're using, keep track of the parameters you're typing, and add calls to properties and methods with only a few keystrokes.
Many aspects of IntelliSense are language-specific. For more information about IntelliSense for different languages, see the topics listed in the See also section.
List Members
A list of valid members from a type (or namespace) appears after you type a trigger character (for example, a period (.) in managed code or :: in C++). If you continue typing characters, the list is filtered to include only the members that begin with those characters or where the beginning of any word within the name starts with those characters. IntelliSense also performs 'camel case' matching, so you can just type the first letter of each camel-cased word in the member name to see the matches.
After selecting an item, you can insert it into your code by pressing Tab or by typing a space. If you select an item and type a period, the item appears followed by the period, which brings up another member list. When you select an item but before you insert it, you get Quick Info for the item.
In the member list, the icon to the left represents the type of the member, such as namespace, class, function, or variable. For a list of icons, see Class View and Object Browser icons. The list may be quite long, so you can press PgUp and PgDn to move up or down in the list.

You can invoke the List Members feature manually by typing Ctrl+J, choosing Edit > IntelliSense > List Members, or by choosing the List Members button on the editor toolbar. When it is invoked on a blank line or outside a recognizable scope, the list displays symbols in the global namespace.
To turn List Members off by default (so that it does not appear unless specifically invoked), go to Tools > Options > All Languages and deselect Auto list members. If you want to turn off List Members only for a specific language, go to the General settings for that language.
You can also change to suggestion mode, in which only the text you type is inserted into the code. For example, if you enter an identifier that is not in the list and press Tab, in completion mode the entry would replace the typed identifier. To toggle between completion mode and suggestion mode, press Ctrl+Alt+Space, or choose Edit > IntelliSense > Toggle Completion Mode.
Parameter Info
Parameter Info gives you information about the number, names, and types of parameters required by a method, attribute generic type parameter (in C#), or template (in C++).
The parameter in bold indicates the next parameter that is required as you type the function. For overloaded functions, you can use the Up and Down arrow keys to view alternative parameter information for the function overloads.
When you annotate functions and parameters with XML Documentation comments, the comments will display as Parameter Info. For more information, see Supply XML code comments.
You can manually invoke Parameter Info by choosing Edit > IntelliSense > Parameter Info, by pressing Ctrl+Shift+Space, or by choosing the Parameter Info button on the editor toolbar.
Quick Info
Quick Info displays the complete declaration for any identifier in your code.
When you select a member from the List Members box, Quick Info also appears.
You can manually invoke Quick Info by choosing Edit > IntelliSense > Quick Info, by pressing Ctrl+K, Ctrl+I, or by choosing the Quick Info button on the editor toolbar.
If a function is overloaded, IntelliSense may not display information for all forms of the overload.
You can turn Quick Info off for C++ code by navigating to Tools > Options > Text Editor > C/C++ > Advanced, and setting Auto Quick Info to false.
Complete Word
Complete Word completes the rest of a variable, command, or function name after you have entered enough characters to disambiguate the term. You can invoke Complete Word by choosing Edit > IntelliSense > Complete Word, by pressing Ctrl+Space, or by choosing the Complete Word button on the editor toolbar.
IntelliSense options
IntelliSense options are on by default. To turn them off, choose Tools > Options > Text Editor and deselect Parameter information or Auto list members if you do not want the List Members feature.
IntelliSense icons
The icons in IntelliSense can convey additional meaning with icon modifiers. These are stars, hearts, and locks layered on top of the object's icon that convey protected, internal, or private, respectively.
| Icon | Accessibility | Description |
|---|---|---|
| Public class | Access is not restricted. | |
| Protected class | Access is limited to the containing class or types derived from the containing class. | |
| Protected internal class | Access is limited to the current assembly or types derived from the containing class. | |
| Internal class | Access is limited to the current assembly. | |
| Private class | Access is limited to the containing class or types derived from the containing class within the current assembly. (Available since C# 7.2.) |

Troubleshoot IntelliSense
The IntelliSense options may not work as you expect in certain cases.
Visual Studio Code Intellisense C++
The cursor is below a code error. You might not be able to use IntelliSense if an incomplete function or other error exists in the code above the cursor because IntelliSense might not be able to parse the code elements. You can resolve this problem by commenting out the applicable code.
The cursor is in a code comment. You can't use IntelliSense if the cursor is in a comment in your source file.
The cursor is in a string literal. You can't use IntelliSense if the cursor is in the quotation marks around a string literal, as in the following example:

The automatic options are turned off. By default, IntelliSense works automatically, but you can disable it. Even if automatic statement completion is disabled, you can invoke an IntelliSense feature.
