People usually duplicates validation rules in AngularJs and on the server side. Server side validation works properly, but validation messages are not be dispatched automatically to the user interface. You need to show server side errors in a message box
or some other custom display area.
If you use knockout.js for the SPA there are tricky ways to use both client side and server side Asp.net stack validation based on validation attributes (you need to write some not trivial Js code, however), but with angulaJs this is quite impossible.
