What technology stack to use in my web application?

Question

Hi,

I have prior ASP.Net web application experience of 5 years, in this era i haven't impletemented any JavaScript frameworks in my any web application. Now my company have got a big "sales" web application project so I am planning to built it using JS framework i.e. **ANGULAR JS 6**

Now i will learn AngularJS as a front-end techno, but for the server side I know that it is very hard and nearly impossible to merge it with asp.net web forms tech. So for this reason I am thinking to learn either ASP.Net MVC or ASP.Net Core.

Can you please guide me which technology works best and should I learn with Angular JS? also which techno stack will suit me most in future with any steep learning curve?
