Regarding using the SPA Templates with VS2017 15.3.3
Posting this in hopes that it is helpful. I worked out the issue for my situation.
Symptoms:
A. Development Machine

Project generated with "dotnet new ".
Runs fine on local development machine (Win7Pro64).
Only .net Core 2.0 installed.
NOTE: no changes to Project, exactly as generated from template engine.
Switch to "Release" and set ASPNETCORE_ENVIRONMENT to "Production"
Publish with Web Deploy Package method.

B. Over to the Server

Win2008R2SP1(64)
New HyperV...never used to host web services.
Set up per instructions https://docs.microsoft.com/en-us/aspnet/core/publishing/iis
Install Web Deploy 3.6 via WPI.
Import published application using Deploy
ERROR 502.5 (both from "Browse" locally and remote machine) Latest Google Chrome in both cases.

Punchline: installed .net core 1.1.2 runtime on server, 502.5 error goes away and application works fine.
