I've tried adding the DefinitelyTyped NuGet packages, but they don't seem to add any content to my project so I don't know how to reference them.
It looks like I should use TSD, but does that apply to every project? How does TSD know what typings I want for each project? I found this that mentions TSD: How do I add a TypeScript definitely typed definition in ASP.NET 5?
Is there a new way that it's supposed to be done? I found the "Search for typings" in the context menu when you right click on a .js file, but that just does a NuGet search.
