json asmx and that pesky d:

Question

I have looked through lots of Posts and have not been successful in determining how to get rid of the pesky d in the response coming from my asmx web service, as in {"d":{"Response":"OK","Auth-Key":"JKPYZFZU"}}.

This is being created by my class 'public Dictionary UserDevice' by returning the Dictionary object.

I would be perfectly happy if the damn thing just wouldn't put it all into the d object!

Answer 1

You are probably using some kind of framework that automatically wraps your web service json responses with the d element.

I know that microsoft's JSON serializer adds the d on the server side, and the client-side AJAX code that deserializes the JSON string expects it to be there.
I think jQuery works this way too.

You can read a little more about this at Rick Strahl's blog

And there is a way for you to return pure json (without the 'd' element) using the WCF "Raw" programming model.

Answer 2

You can read about why it's there here:
