Web API - 405 - The requested resource does not support http method 'PUT'

Question

I have a Web API project and I am unable to enable \"PUT/Patch\" requests against it.

The response I get from fiddler is:

HTTP/1.1 405 Method Not Al         


        

Answer 1

This is also the error message returned if you forget to make the Put() method on your API controller public. Which is obvious in hindsight, but caused me a good ten minutes of head-scratching.
