I was wondering what currently is the lightest VS project to make calls to a web API and that can be hosted on IIS? From what I see available, I can either do an ASP.NET WebApp or WCF Service Application. However I'm not sure which one would be considered overkill for something that will only interact with Active Directory and make a few calls a day.
edit: After reading this SO Question and the provided link to an official comparison I realize it's pertinent to note that half of the calls to to be made will be triggered through a browser.
