Previously, when the typeRoots option was specified in a tsconfig.json but resolution to any typeRoots directories had failed, TypeScript would still continue walking up parent directories, trying to resolve packages within each parents node_modules/@types folder. Second, if a function has no return expressions and is being passed to something expecting a function that returns undefined, TypeScript infers undefined for that functions return type. The cause seems to be Visual Studio was using cached nuget packages when restoring. The ESLint extension integrates ESLint into VS Code so you can see linting errors right in the editor and even quickly fix many of them with Quick Fixes. Within these new projects, you can run JavaScript and TypeScript unit tests, easily add and connect ASP.NET Core API projects and download your npm modules using the npm manager. I dont normally run VS As Administrator do we have to for this? These front-end projects are created using the framework CLI tools you have installed on your local machine, so the version of the template is up to you. Today we are excited to announce a new experience for JavaScript and TypeScript Note: The minimum supported version of this package is 2.1.
