What is better to choose for a simple web service?

Question

ASP.NET

It was necessary to implement a web service that will process a get request with a single parameter and return the result in xml.
The service uses a database and must be able to launch an executable from under a specific domain account on the host where the service lives.
Windows environment: iis, mssql.
On win, there is no development experience for the web, only console applications on c # .net.
Advise what to take so that there is less code and a simpler structure? Classic asp, mvc, razor?

Answer 1

Look towards ASP.NET Web API.

Answer 2

if all that the code has to do is to process exactly one type of request and issue data in xml - isn't it easier to use HttpListener? why is IIS here?

Answer 3

ASP.NET MVC I think there are no options.
