Vue + Vuex is where we went after Angular 1.x. We're also a C# shop and felt burned by the Angular 2+ changes. We worked with React and really liked it, but it was hard to bring on new devs quickly.

Vue is a lot like Angular with data binding, only about a million times easier to get going than React. Vue + Vuex (feels like a really well thought out Mobx) + Vue-Router and you'll be knocking out slick looking web apps in no time.

Also the vue-cli is like a gift from a more intelligent Javascript writing species.
