ASMX is for SOAP services. They are a legacy technology and you should really avoid using it. If you're using the MS stack, Web API works perfectly with Angular (and any other JS framework). You can get WCF to also work with it but it requires much more configuration to do the same thing a Web API project can provide with almost no configuration.
