Question

With AngularJs + Web API, why we need ASP.NET MVC and IIS?

Can I just use AngularJS plus WEB API to develop a web application without IIS and ASP.NET MVC ?

Answer 1

It is definitely possible from the technology point view. I see 2 areas of concern:

1. Would clients with outdated browsers have problems accessing the site? This is less of a problem as new versions of browsers are getting released.

2. Are the non-IIS hosted hosted Web API services robust and scalable enough?
