I have a problem with the Intellisense on Typescript files in Visual Studio 2022 (on 2019 I didn't have this issue). From time to time the Intellisense stops working and the only solution I have is to exit from Visual Studio and reload the project. Is there any solution to force the the Visual Studio to reindex the files and hopefully the Intellisense will start working or are any other hidden settings that can help me to fix this annoying issue?

If you find IntelliSense has stopped working, the language service may not be running. Try restarting VS Code and this should solve the issue. If you are still missing IntelliSense features after installing a language extension, open an issue in the repository of the language extension.
IntelliSense shows you intelligent code completion, hover information, and signature help so that you can write code more quickly and correctly. VS Code provides IntelliSense for individual TypeScript files as well as TypeScript tsconfig.
To access this options page, choose Tools > Options, and then choose Text Editor > C# > IntelliSense.
For Visual Studio 2017 (and I think Visual Studio 2019 also), close Visual Studio, go into the . vs folder in your projects folder and delete all the contents apart from the . suo file, then reopen Visual Studio. This way you can rebuild the Intellisense cache without losing your preferences.
This is not a problem with typescript. In visual code 1.9 onwards they have security issues.It try to read some data from your windows drive and if you do not have rights then it do not show intellisense. If you do not have full admin rights on your system then uninstall 1.9.x version and install VSCodeSetup-1.8.1
The TypeScript language specification has full details about the language. Visual Studio Code includes TypeScript language support but does not include the TypeScript compiler, tsc. You will need to install the TypeScript compiler either globally or in your workspace to transpile TypeScript source code to JavaScript ( tsc HelloWorld.ts ).
Visual Studio Code IntelliSense is provided for JavaScript, TypeScript, JSON, HTML, CSS, SCSS, and Less out of the box. VS Code supports word based completions for any programming language but can also be configured to have richer IntelliSense by installing a language extension. Below are the most popular language extensions in the Marketplace.
To allow JavaScript/TypeScript projects to also be easily debugged using Visual Studio Code, we’ve included a launch.json file to the project template. This file will be used to set your launch configurations in Visual Studio, as well as in VS Code.
please try the latest typescript version with the command:
npm install -g typescript@latest
I had the same problem with a large project that I copied over from an old machine on my new one. After searching around I found the answer. I found that the typescript types were not up to date so I firstly installed typesync by using the following command:
npm install -g typesync
Then in the clientapp folder I ran it (as it looks for the package.json file):
typesync
After restarting the project all was good!
