We are working on migrating our application to a new Angular version. The old one (Angular.JS) was it\'s own application/repo being served by an .NET Framework 4.5.2 ASP.NET
Have you made any modification to your Web.config file? You need to set it up for the base angular app (using the UrlRewrite module) I'd assume it might need a modification for your use case...
My assumption is you will need to add another 'rule' here. Hope this helps!!! (note: the rewrite is supposed to match your ng build base href value)
