The HTTP protocol is inherently functional. It's simple, stateless interface taking a request and returning a response should be quite familiar to functional programmers. In this series, we'll investigate the benefits of taking a functional approach to building HTTP applications using Microsoft's Visual F# and ASP.NET Web API tools.

1. Introduce the tools: F# and ASP.NET Web API
2. Functional Nature of HTTP: Request -> Response
3. Evolution: Request -> Task<Response> or Request -> Async<Response>
4. Functional Core of Web API: System.Net.Http
5. Introduce the ApiController type and the MVC style of developing with Web API
6. Composing Web APIs
7. A Functional DSL for building Web APIs: Frank
