How can I use TSLint in VS Code?

The vscode-tslint extension currently crashes silently when it encounters an invalid config-option. In my case, it was the no-trailing-comma rule which has to be changed to trailing-comma.

In my case it was the .vscode/tasks.json file. I removed and recreated the file and its all working fine now.

On a new machine, I installed VS Code tslint extension before installing tslint itself (via npm), and nothing helped to make it work other than disabling and re-enabling the extension.

VS Code doesn't give any warning. What does this extension do

When in doubt. Restart VSCode.
