While preparing for the first tutorial in the new web services subject that I'm tutoring I came across the following exception: "Request format is unrecognized for URL unexpectedly ending in '/ConvertTemperature'". Unfortunately Google failed me so I decided I'd post the fix I found.

Simply changing the address from "http://localhost/..." to "http://127.0.0.1/..." fixed it right up. I haven't bothered searching for the exact cause of the problem, for a change I'm happy enough with just finding a solution. I do remember coming up against a very similar problem recently so perhaps one day I'll get around to explaining this fully. In the meantime this is an adequate solution.

So next time you get the error "Request format is unrecognized for URL unexpectedly ending in '/???'" while developing asmx web services in ASP.NET 2.0 try this as a solution.
