I am working in the context of Visual Studio 2015 (with Resharper), and am referencing a TypeScript definitions file for NodeJS. I have 3 other VS projects that are using
VS 2019, click Extensions->search for Typescript 3.8 for VS, click to install, restart VS,
the the VS/ReSharper will recognize the feature of Typescript 3.8. in project file Latest using "Latest" is a smart way.
