Introduction

If you are seeing this message in Visual Studio, it is likely that the problem is with one or more of your Visual Studio extensions. Fortunately, there is an easy way to fix the problem.

1. Open the Extensions and Updates dialog from the Tools menu.
2. Select the Updates tab at the top of the dialog.
3. In the list of updates, find and select “Visual Studio 2015 Update 3”.
4. Click Install in the upper right corner of the dialog.
5. Restart Visual Studio when prompted.
   What is intellisense?

IntelliSense is a code completion tool that makes it easier to write code in a programming language. It provides suggestions for variables, functions, and other elements of the code as you type. IntelliSense can be found in many popular code editors, such as Visual Studio and Visual Studio Code.

Why is intellisense important?

Intellisense is a valuable tool for coding because it provides suggestions as you type based on the code you have written so far. This can be helpful in finding errors, understanding what options are available to you, and improving your code’s readability.

How to get intellisense back

If you are having trouble with intellisense in Visual Studio, there are a few things you can try to get it back.

First, make sure that you have the latest version of Visual Studio installed. If you are using an older version, intellisense may not be available for some features.

Next, try resetting your user data. This can be done by going to Tools > Import and Export Settings and selecting the Reset all settings option. This will reset all of your user settings, including IntelliSense.

If neither of these options work, you can try manually deleting your IntelliSense cache. This cache is located in the %APPDATA%\Microsoft\VisualStudio[version]\IntelliSense directory. Deleting this cache will force Visual Studio to regenerate it, which may fix your issue.

Conclusion

If you’re seeing this message, it means that either you don’t have the TypeScript Compiler installed, or it’s not in your path. This is usually caused by one of two things:

You’re working in an environment that doesn’t have the TypeScript Compiler installed (such as a plain text editor). In this case, you’ll need to install the TypeScript Compiler yourself.

The project you’re working on uses an older version of the TypeScript Compiler than the one you have installed globally. In this case, try installing the older version of the compiler locally within your project.
