Map Physical Paths with an HttpContext.MapPath() Extension Method in ASP.NET

There's no easy way to simply retrieve raw data to a parameter in an API method, so a few extra steps are provided using either manual handling of the raw request stream, or by creating custom formatter that can handle common 'raw' content types in your APIs via standard Controller method parameters. In this post I look at various permutations and how you can access the raw data in your code.
