ASP.Net Core 2 - Using Url.Action to generate url to web api behaves differently?

I've used the helper Url.Action to pass relative URLs from MVC views to Typescript/Javascript classes before in full ASP.Net MVC with success. Here is an example, in a cshtml file:

let vm = new VM('@Url.Action("Names", "api/Data")');

The Typescript class constructor is passed the following string in full ASP.Net: "/api/Data/Names", but in ASP.Net Core 2, the passed URL is "/api%2FData/Names", which is an invalid URL. I can't figure out if this is intended or a bug.

Thoughts? Thanks.
