ASP.NET WEB API without Visual Studio?

After reading http://msdn.microsoft.com/en-us/library/vstudio/ms751457(v=vs.100).aspx I discovered I could create a single source code file with the ".svc" extension and copy it to a public IIS andviola!  Instsant web service!  This is great for proof-of-concept demos, tutorials and prototypes (and even responding to interview questions).

Can anyone tell me how to make a ASP.NET WEB API using only notepad with a minimal number of source code files (no visual studio) that I can easily deploy by just copying source code files to a public IIS?

Thanks
