I'm about to create an API for a existing .NET application and want to go the RESTful service route. Our backend platform is .NET and MSSQL. I'm hoping for a good blend or scalability combined with clean architecture.
Are there any strong opinions on the best way to implement a RESTful .NET API (WCF, standard ASP.NET, MVC or even HTTP Listener)?
Also any opinions on why NOT to go with .NET or reasons to use something like RoR.
