How to solve the problem of IntelliSense not working in VS Code

Visual Studio Code, most commonly known as VS Code, is one of the tools developers use for coding. Intellisense is a feature included in VS Code that makes coders’ lives easy. It provides suggestions or tool tips for writing code. This is the kind of extension that developers prefer. People who are used to IntelliSense will find it difficult to code when it doesn't work. Are you one of them? If so, go through this article to find different solutions to fix IntelliSense not working in VS Code.

Intellisense is shown below. It provides suggestions as you code.

It’s always good to check the basics first. What I basically mean is to check if IntelliSense was uninstalled by mistake and check by reloading VS Code. Also, keep in mind that if assuming you have IntelliSense for python installed, it will only work with python and not other languages. If you use multiple programming languages, you will need to install it for each language separately.

Method One: Reload VS Code

If IntelliSense is installed but still not working, restarting/reloading the program will solve the problem in most cases. So give it a try.

Step 1: To restart VS Code, open VS Code and press the Ctrl Shift P keys simultaneously to open the Command Palette and type Reload Window in the search.

Step 2: Click Developer: Reload Window. This will reload VS Code.

Method 2: Check if IntelliSense is installed

Step 1: Open Visual Studio Code, on the left, there are different options hover over these options to find out what they are.

Step 2: Use the Ctrl Shift X keys simultaneously to open the extension tab. Alternatively, you can hover over the option and click Extensions.

Step 3: Type the programming language you want IntelliSense to use in the search bar leaving a space and then type IntelliSense. For example, let’s say you need IntelliSense for Python, so type python IntelliSense

## Step 4: A list of extensions will appear, select the most suitable extension. Once you select an extension, you can see on the right the different features included in that particular extension.

Step 5: If the selected extension is already installed, you won't see the install button there.

Step 6: If it is not installed, there will be an option saying install it. Click on it to

install. You can see the difference between installed and non-installed extensions in the image below. An installed extension displays a settings symbol, and another extension that is not installed displays an install button.

Step 7: If you get reload option reload the IDE otherwise follow the steps mentioned in method 1 to reload.

Method 3: Restart and update VS Code

Step 1: Click the Start button in the lower left corner to restart the system.

Step 2: Click the power button and then click the Restart option.

Step 3: Check if IntelliSense is working, if not update VS Code.

Step 4: To

update VS Code, open VS Code and click Settings in the lower left corner of VS Code.

Check for Updates from the list that appears. This will check if there are any updates and if so, it will install them. RestartVS Code after installing the update.

Step 6: If updates are not available, a dialog box will appear stating that there are currently no updates available. Click

OK.

Method 4: Reinstall VS Code

If none of the above methods work, then the last option is to reinstall VS Code. I know this is frustrating, but since you've tried all of the above and haven't found it to work, reinstalling VS Code will resolve the IntelliSense issue.

Step 1: To uninstall VS Code, simultaneously click the Windows R key to open the run prompt and type

appwiz.cpl

Step 2: This will open Programs and Features. Scroll down to find Visual Studio Code.

Step 3: Right-click Microsoft Visual Studio Code and click Uninstall.

Step 4: To download VS Code, visit the manufacturer’s website and click on the operating system you are using. For example, here I am using Windows, so click the Windows button to download the Setup(.exe) file.

Step 5: Once the download is complete, click on the downloaded .exe file and follow the on-screen instructions to install.

Step 6: Open VS Code, now since it is a fresh install it will not have the IntelliSense extension. To install IntelliSense, follow method 2.

This will solve the problem and you can start coding easily.
