I am trying to use angular in my main asp.net project. Using this repo https://github.com/cadabloom/AspNetCoreAngular for angular tempating.
Getting this error whenever I build project.as I checked vendor.js, I found that webpack is not updating files in ClientApp.
An unhandled exception occurred while processing the request.
Exception: Call to Node module failed with error: Error: No ResourceLoader implementation has been provided.Can't read the url "app.component.html"
